SAP IDT &-8211; Overview & User Interface

Information Design Tool (IDT) is a Business Objects design tool that extracts the data from different data sources using an OLAP and Relational connection to create Universes. There are different Universe parameters that can be passed at time of Universe creation.

A Universe is called as logical collection of dimensions and objects that allow business users to analyze the business data. Objects and dimension represent different hierarchies, measures, custom calculations, and attributes.

Universe can be created on the top of relational databases like SQL Server, Oracle or also on top of an InfoCube in SAP Business Warehouse (BW) system. Different types of connections can be created to these data sources like personal connection, shared connection and a public connection. A SQL or MDX statement is generated according to data source respectively &-8211; Relational and an OLAP.

A Universe created using an IDT can be used with different reporting tools in Business Objects. When a Universe is published to a central repository, it can be used in the following reporting and dashboard tools −

  • SAP Business Objects Web Intelligence (WebI)
  • SAP Business Objects Dashboard Designer (Earlier known as Xcelsius)
  • SAP Business Objects Crystal Reports
  • SAP Business Objects Explorer

User Interface

Different Components in IDT while Designing a Universe

An OLAP or a Relational connection to data source

  • Extracting the tables and joins from Relational database or an OLAP cube.

  • Building a data foundation from extracted tables and joins.

  • Creating metadata objects from data foundation layer and these objects are managed in Business layer.

  • Using Universe parameters and to share the resources in Universe.

  • Publishing a Universe which includes Business layer, Data Foundation and a Universe connection to database

Universe can be published to the central repository to be used by other SAP Business Objects reporting applications.

Security profiles are used to provide access on Universe data and metadata objects.

IDT is primary used by application managers and report developers who wants to create analytical reports on the top of data stored in the different data sources. To create reports on top of Universes, a person needs technical understanding of IDT tool and functional knowledge of Data Warehouse.

SAP IDT &-8211; Resources

There are various resources in Information Design Tool that can be used to extract the data from data sources and to create a Universe −

Project

A Project is a local workspace where you store the resources used to build one or more Universes. This is used to manage the local objects, which are used for Universe creation. A single project can contain objects for one or multiple Universe. A local project can contain multiple number of objects like data foundation layer, business foundation, and data source connection, etc.

Project

Data Foundation

Data Foundation layer allows you to import tables and joins from different relational databases. All the joins are imported and you can also define derived tables, custom calculations, additional joins, contexts and prompts.

Data Foundation

Relational and OLAP Connection

A connection is used to define how data is extracted from a relational or an OLAP data source. A Universe always uses at least one connection to extract the data. You can also build a multisource that extracts data from one or more data sources using multiple connections.

A connection can be saved locally with .cnx file and all Universes created on the top of local connections can’t be published to BO repository. To publish a Universe to repository, you should use a secured central connection with .cns file.

.cns- secured Repository connection

.cnx-local unsecured connection. If you use this connection, it will not allow you to publish anything to repository.l

OLAP Connection

Business Layer

In Business layer, you define measures and dimensions. You can also apply Aggregations like Sum, Count, Avg, Min, Max.

To complete the Universe creation, you need to save the project and then publish the business layer to the repository.

Universe Creation

UDT vs IDT

In UDT, a Universe is created with file extension as .unv. In IDT, a Universe file extension is changed to .unx file.

To open unv file in IDT, it can’t be directly opened but you can convert unv file to unx file to open in Information Design tool. You can’t open an IDT .unx file in Universe Design tool nor you can convert it to unv file.

Universe Design Tool is a single-source enabled tool. However, IDT is a multi-source enabled tool meaning you can extract the data from different data sources while creating a Universe.

Universe Design Tool (UDT) Information Design Tool (IDT)
Universe file extension- .unv Universe file extension &-8211; .unx
You can’t open .unx file and also it can’t be converted to unv to open in UDT You can open unv file by converting unv file to unx file extension
It is single-source enabled It is multi-source enabled
It can’t be directly connected to Dashboard designer and Crystal Reports latest version It can be directly connected to Dashboard designer and Crystal Reports latest version

User Interface in IDT

When you retrieve an existing Universe in IDT by connecting to the repository, following are the available interfaces. These are the same when you design a new Universe in Information Design Tool.

User Interface IDT

Once you click on finish, it will create a secure Repository connection.

Secure Repository Connection

.cns − secured Repository connection

.cnx − local unsecured if you use this connection it will not allow you to publish anything to repository.

Local Project

The next step is to create a Data Foundation Layer on this secure connection.

Right-click on .cns Repository connection → New Data Foundation.

New Data Foundation

Enter Resource Name and click on Finish. It will show you a list of all available schemas in the database. You can add Tables and Joins from Schema to Data Foundation layer. This can be done by dragging the table or by a double-click. Apply the joins on Dimension and Fact tables to create a logical schema.

New Logical Schema

To define a Join, double-click on Join between tables. It will show you both the tables. You can select from different Joins as per data requirement and click on detect Cardinality to define cardinality &-8211; 1:1, 1:n, n:n.

Join Definition Details

Next is to create a Business Layer on the Data Foundation. Click the Save All icon at the top of the screen. Then, right-click on Data foundation .dfx → New Business Layer.

New Business Layer

Enter Resource Name → (Generating Business Layer for Data Foundation) Finish. It will add Business Layer .blx under the Local Project.

It will show a list of all dimensions and measures under Data Foundation. You can define dimensions, measures, aggregation, etc.

Dimensions Under Data Foundation

To define an Aggregation, you can select from Projection Function. You can also hide few objects in the report if you want by using the dropdown next to measures and dimension. You can select Hidden for a particular object.

Project Function

Once you define Business Layer, click Save All icon at the top of the screen as shown in the following screenshot.

Define Business Layer

To publish a Universe to the Repository, right-click on .blx → Publish → To a Repository.

Select Resources → Next → In Publish Universe window, select Next → Select the Repository folder where you want to publish Universe and click Finish.

Repository Folder

You will get a confirmation that Universe published successfully.

To check the Universe under Repository, go to Repository resources and check for the Universe that has been created.

Check Universe

Creating a Universe on SAP ERP

You can build a universe on SAP ERP by using Data Foundation in IDT. You have to create a relational connection to ERP data source, info sets, SAP queries, and ABAP functions that are treated as tables in the connection.

You can create a single source Data Foundation to support local connections but it doesn’t support Joins and calculated columns between the tables inserted from an ERP connection.

To use a calculated column, joins, you need to create a Data foundation that is multi-source-enabled on a secured connection.

Creating a Universe on SAP ERP

When a table is added in Data Foundation layer, the table type of info set, SAP query, or ABAP function is saved as a table property in the data foundation. To add an ABAP Function table, there is one data foundation table created to map the main function.

The table contains input columns for the input parameters of the function. These parameters can be mandatory or optional. To assign a value to mandatory parameters, you need to edit the input columns.

Limitations of Using SAP ERP

When you use measures that contain aggregate functions it can’t be used as filters in the Query Panel as the output SQL expression consists of HAVING clause, and it is not supported by the SAP ERP connection. Hence, if a measure is added that contains Aggregation function as filter, it throws an error while refreshing the query.

Creating a Universe on SAP BW

If you want to use SAP BW to design a Universe, you should use a data foundation based on multi-source enabled structure. All the tables and joins in SAP BW are automatically imported to Data Foundation. When a Business Layer is created on Data Foundation, all objects are automatically moved to the Business Layer.

Creating a Universe on SAP BW

If you don’t want to insert tables and joins automatically, you can unselect the Detect tables by going to advance properties while adding connection to Data Foundation.

You can also turn off insertion of Business Layer objects by unchecking the option to automatically create classes and objects when selecting data foundation in New Business Layer.

Creating a Universe on Microsoft Analysis Services

You have to create Business Layer on Microsoft Analysis Services (MAS) and business layer objects are created by default. Following is the mapping of objects in Business Layer −

  • Dimension − Analysis dimensions are created in the business layer for each dimension in the cube.

  • Display Folder − Folders are created in the analysis dimension to contain the hierarchies in the display folder.

  • Hierarchy − For value-based (parent-child) hierarchies, a value-based hierarchy is created in the analysis dimension. The attributes are created in the Attributes folder in the hierarchy.

  • Attribute Hierarchy − Attribute hierarchies in the cube are created as level-based hierarchies in the analysis dimension.

  • Named Set − Named sets are created in the related analysis dimension, in the folder Named sets.

  • Measures and Calculated Measures − Measures and calculated measures are created as measures in the appropriate measure group folder. A measure attribute is created for the formatted value.

Creating a Universe on SAS

You can build a Universe on SAS by using multi-source enabled data foundation and using a secure connection.

Connection to SAS data source are managed by data federation service.

Multilingual Universes

You can also create multilingual Universe in Information Design tool. This allows you to use multilingual solution by using single Universe metadata model.

Following are the steps to use multilingual Universe for report creation −

Step 1 − Use Universe designer to design Universe in source language in IDT.

Step 2 − Use translation management tool to translate the metadata in the data foundation and business layer.

Step 3 − Use report designers to build the reports on the same Universe, which can be displayed in different languages as per user preferences.

Step 4 − Go to Information Design Tool → Preferences → Preferred Viewing Locale determines the language of the metadata and data in the Query Panel.

Preferences Tab

This can be used if you have support for the following −

  • Translations are available in the language (metadata).

  • The connection supports the language parameter (data).

SAP IDT &-8211; .unv Universe Introduction

A .unv Universe is created in Universe Designer in SAP Business Objects XI 3 or Universe created using Universe Design tool. It can be converted to unx file in Information Design tool.

Following SAP Business Objects version can create unv files −

  • Universe Design Tool (UDT)

  • Universe Design Tool Desktop Edition

  • Universe created using UDT is stored with a file name .unv in the local folder or in the central repository

If you select this option, the deletion is permanent and cannot be undone. Click on “Yes” to confirm the deletion.

If you did not delete the project contents permanently, you can open the project to make it available.

Project Synchronization

Project synchronization deals with comparing resources in local project views with an associated shared project in the repository. Using project synchronization, you can detect add/delete resources, difference between resources. Based on differences, the local project view and shared resources can be updated.

Under Project synchronization, there are two different panes −

Shared Project Pane

It lists the resources in shared project on the server. If there is a lock icon in the form of resource, it means the resource is locked. Synchronization status lists the status of each resource by comparing resources in shared and local project views.

Different Synchronization Status

Added Locally − A resource is added in the local project but not in the shared project.

Changed Locally − A resource was changed in the local project but not in the shared project.

Deleted Locally − A resource was deleted in the local project but still exists in the shared project.

Added on server − A resource is not in the local project but exists in the shared project.

Changed on server − A resource was changed in the shared project but not in the local project.

Deleted on server − resource exists in the local project but was deleted in the shared project.

Synchronize − Both resources are identical.

List of Resources in Synchronization Status Pane

Shows all resources. This clears the filters and lists all resources regardless of their status.

For larger resources (data foundations and business layers), you can select which metadata elements to include in the report in the Metadata Elements box.

Click Generate to create the report.

SAP IDT &-8211; Managing Connections

A connection in IDT is used to connect to a relational or an OLAP data source using SAP BusinessObjects reporting tool. It can be a local connection or a connection published in a central repository.

Different Types of Connections Supported in IDT

Following are the types of connections that are supported in IDT −

Relational Connection

This is used to design Data Foundation layer in Information Design tool. You can import tables and joins from data source.

OLAP Connection

Using an OLAP connection, you can design a business layer while creating a Universe. It allows you to connect to multidimensional schema directly and to import them for Universe design. Later, they can be used with SAP Business Objects reporting tool.

BICS Client

To connect to SAP NetWeaver BW, you can use SAP BICS client middleware to provide access to BEx query. Connections in IDT can be locally saved or they can be secured and published in a central repository.

Local connections are saved as .cnx files and they can be accessed by any user who is running IDT. Once you publish the connection to the repository, they are changed to a secured connection.

A secured connection is published into the repository and saved in Connection folder. You can also create secured connections by using Insert Relational and Insert OLAP connection commands from the repository resource view.

Following are the key properties of a secured connection −

  • Users must be authenticated.

  • User rights can be defined at the user level to grant or deny access to connections or connection properties.

  • Secured connections can be used or shared by authenticated users.

Creating a New Connection in IDT – Relational

Go to Information Design tool under BI client. To create a new Relational connection, first start with a new project under Local Project view.

Click New → Project → Enter the Project Name → Finish.

Right-click on Project name → New → Relational Connection.

New Connection in IDT

Enter the connection/resource name → click Next.

Resource Name

Select the middleware as per data source. You can select SAP or non-SAP as data source and set up a relational connection to the database.

We have selected SAP from the list → SAP HANA → JDBC → click Next.

Middleware Database

Enter the Authentication mode, user name and password. Enter the host name and the Instance number and click Next.

SAP HANA Database

In the next window, you can define connection parameters like &-8211; Time out, Array fetch size, Array Bind size, etc. Click Finish.

Define Connection Parameters

A Relational connection to source database is created with .cnx file extension. You can click Test Connection.

Test Connection

Lower part of Window tells you about connection parameters &-8211; Login parameters, configuration parameters, etc.

→ Test Connection → Successful

Similarly, you can create a Relational connection for other data sources.

We have to publish this connection to the Repository to make it available for use.

Right Click on connection name → Publish connection to Repository → Enter BO repository password → Connect → Finish → Yes.

Enter BO Repository

.cns- secured Repository connection

.cnx-local unsecured &-8211; If you use this connection it will not allow you to publish anything to the repository.

This shows how a relational connection can be created in the Information Design Tool. To summarize the steps that are involved in creating a connection −

  • Enter the name of the connection
  • Select the middleware for the target database
  • Enter the login parameters to connect to the relational data source
  • Configure and customize parameters to optimize the connection and Finish
  • To change it to secure, publish the connection to the Repository

Renaming or Deleting a Connection

To rename or delete a connection, right-click on connection name under Local Projects area.

Renaming Connection

You can also delete or edit a Relational connection like this.

Creating a New Connection in IDT – OLAP

An OLAP connection is used to connect to multidimensional view or a data model to design Business Layer in Information Design tool.

To create a new OLAP connection, right-click on Project name → New → OLAP Connection.

OLAP

Enter the connection name, description and click Next.

Connection Name

Next, select an OLAP middleware driver. It shows a list of all available OLAP data sources. You can select any of OLAP data source as per requirement.

Note that you don’t need to create a Data Foundation, as an OLAP directly hits the Business Layer. You can define dimensions and measures and other properties at Business Layer.

Select the suitable middleware driver to connect to OLAP data source and click Next.

OLAP Middleware

Enter the connection parameters, authentication details, system name, instance number, etc. and click Next.

Parameters of OLAP Middleware

You can also select a specific cube to connect or all the cubes in the design time repository. If you select a particular cube, then using this OLAP connection you can design Business Layer only on the objects available in that cube.

OLAP Connection

Click Finish.

Now, you need to publish the connection to the Repository. Right-click on connection → Publish the Connection to the Repository.

Repository Connection

Login Parameters for Connection

When you create a relational or an OLAP connection in IDT to connect to any data source, you have to provide login parameters of source database such as Host Name and Instance Number.

Login Parameters for Connection

Connection Parameters

While creating a connection, you can configure various connection parameters −

SAP IDT &-8211; Data Foundation Layer

A Data Foundation contains one or more tables and joins from one or more relational databases that forms the design of Business Layer. A relational connection is used to design Data Foundation layer. You can add various other objects at Data Foundation that enhances the capabilities like &-8211; Derived tables, custom calculations, context, LOVs, etc.

It is also possible to design multiple Business Layers on a single Data Foundation thus allowing you to build multiple Universes on single Data Foundation Layer.

Types of Data Foundation

In Information Design Tool, you can build Data Foundation that is – Single-source enabled or multi-source enabled.

Single-source Data Foundation supports a single Relational connection. Single Source Data Foundation supports a local or a secured connection so the Universe designed on this can be maintained locally or can be published to the Repository.

Multi-source enabled Data Foundation supports one or more relational connections. Connections can be added when you design the Data Foundation or can be added later. Multi-source enabled Data Foundation is designed on secured connections published in a Repository.

Contexts

Contexts are also used to break the loops in Data Foundation when you are not able to break the loop using an Alias table.

When you have multiple fact tables that are connected to a single dimension table, you create a Context for each fact table in this case.

In a context, there are three states defined for a Join −

Included Joins − In a part of the schema that is ambiguous, the context solves the loop by defining a path with the included joins.

Excluded Joins − In a part of the schema that is ambiguous, the excluded joins define the path that context will never take.

Neutral Joins − They are in a part of the schema that is not ambiguous, and are always included in the query path of the context. Any join that is not explicitly included or excluded is neutral.

A Context can be defined manually or by clicking detect Context option.

To detect Context → Open the data foundation editor by double-clicking the data foundation name in the Local Projects View.

From the Aliases and Contexts pane, select the Detect Contexts icon.

Detect Context Icon

A join that is excluded is shown by the excluded icon Excluded Icon. Click OK to insert the selected contexts into the data foundation.

SAP IDT &-8211; Business Layer

Business Layer in IDT consists of metadata objects like dimensions, measures, attributes, and filter conditions. Business layer can be designed on the top of Data Foundation layer or can be created directly on an Info cube or on a Modeling view in HANA.

When you design a Business Layer, it can be published to the repository or to a local folder. Business layer is used to manage metadata objects before it is published to BI repository.

An Object in Business Layer can have the following three states −

  • Active − This is default state of an object and objects are available in the query panel.

  • Hidden − These objects are valid but are hidden in the query panel.

  • Deprecated − These objects are not valid and hidden.

You can create different type of objects in Business Layer −

  • Dimension − Dimension represents contextual information in Business layer.

  • Measure − Measure represents the factual data on which we perform the analysis. These are numerical values where you perform aggregations and calculations.

  • Attribute − Attribute is defined as an object which is associated with another object to provide more information about the object.

  • Filter − Filters are used to limit the data that are returned in the query. You can define business filters on dimensions and measures by creating and combining conditions.

While using an OLAP data source, you can find the following objects −

  • Hierarchy
  • Level
  • Named Set
  • Calculated member

Aggregate Awareness

Using aggregate awareness, you can use pre-aggregated data in tables in the database. It is used to improve query performance by processing less number of rows.

When you add an aggregate aware object in query, the query generator retrieves the data from the table with the highest aggregation level.

For example − Consider a Sales Fact table where sales is aggregated by per month. If your query asks for sales per month, the query generator will retrieve the data from aggregated table.

Setting Up Aggregate Awareness

To use aggregate awareness, first the aggregated table has to be loaded to database and then add the table to Data Foundation.

Define aggregate aware objects. These are the objects in the business layer for which you want queries to use the aggregate tables when possible, instead of performing aggregation using non-aggregate tables.

In the SQL expression for the object, define the SELECT statement to use the @Aggregate_Aware function −

@Aggregate_Aware(sum(aggr_table_1), …, sum(aggr_table_n))

Aggregate Aware

Select the object in Business Layer → go to SQL Assistant → under Functions → Aggregate Awareness.
