SAP Universe Designer - Quick Guide


SAP Universe Designer - Introduction

SAP Universe Design tool allows users to create, edit or delete existing models published in BO repository. With Universe Designer, you can build data foundation and business layer to meet your BI report requirements and perform different functions available in UDT tool before you develop BI reports and dashboards on top of these Universes. Universe Designer helps you to create semantic layer between your Relational database and BI tool.

With Universe Designer, you can build the semantic layer for non-SAP and SAP data sources to build data models for DB objects. Once Semantic later is built, you can publish it to BO server repository and it can be used by different users to create BI reports in Web intelligence/Desktop intelligence tool and also can be used with other SAP BusinessObjects tools.

The benefits of using Universe for BI reporting is that end users can connect to Universe and run queries against database without understanding the complexity of underlying data structures. BI users can use objects used in Universe to create reports. The advantage of using Universe is to provide easy to use interface to business users which are non-technical, and they can simply drag objects to BI reports and perform ad-hoc reporting without any technical knowledge.

Key Components of a Universe

The following are the key components of Universe −

  • Connection to a database and connection parameters to fetch data.

  • SQL structure called objects which is mapped to actual objects in database- columns, tables, etc., and they are grouped in to classes and these objects are visible to Web intelligence users.

  • Universe contains a Schema which is made up of tables and joins created on top of database objects and is not visible to BI users. Only Universe Designer users can view and edit this schema.

Universe created using Universe Designer Tool has “.UNV” extension. Universe contains classes and objects which are defined as follows −

Classes

In Universe, the grouping of objects is known as class. The name of class normally shows objects category it contains. You can also divide classes in to subclasses based on hierarchical structure.

Objects

In Universe, an object is named component derived from a data object in database. The name of the object is usually based on its relevance to business to users. For example, Objects used by customer should be represented as Customer in Universe layer however it can be referred to XYZ column in database.

In the below image, you can see common example of classes and objects in a Universe. They can be renamed as per requirement from business users.

Object

Universe as Semantic Layer

Universe provides a semantic layer between data warehouse and reporting tool to translate source database objects to objects relevant for business users. It can contain all aggregations for measure values, custom calculations, user prompts and filters, and other business rules relevant for reporting and dashboard requirements.

All tables and joins are applied at Universe level, and business users can simply drag objects in query panel to create BI reports.

Below diagram shows the use of Universe as Semantic layer in BI and DW environment −

Universe Semantic Layer

SAP Universe Designer - Object Types

In a Universe, an object is derived from data in DW system. There are three types of objects used in a Universe as given below −

Dimension

Dimensions are parameters used for analysis and are also linked to hierarchies like time and geography. For example, Product, Customer, Time, Region, etc.

Detail

Detail provides more information about dimensions like Phone number, address, etc.

Measures

Measures are numerical values used in analysis and quantifies a dimension object. Examples include: Profit, Margin, Net Sales, Revenue, etc.

Measures

In the above schema, you can see different dimensions and measure values. Measure values are part of Sales fact table.

Schema in Universe designer are created based on tables and joins to return the data in BI report and dashboards. Business users do not see the schema objects, and these are only visible to Universe designers in UDT tool. Schemas are created in structure pane of Universe window in UD tool.

Schema With Tables

Here you see a schema with tables, joins and columns are used to build it.

SAP Universe Designer - User Interface

When you install BI client tools, Universe Designer is part of client tools and can be opened under SAP BusinessObjects BI Platform Client Tools → Universe Design Tool as shown in the below image −

Universe Design Tool

In above image, you can see Information Design Tool and Universe Design tool both available under SAP BusinessOBjects BI platform client tool. In older version of Business Objects, only UDT was available to design the universe. In BO4.0 or later, Information Design Tool was introduced to add universe created on multiple sources.

Information Design Tool

In the above image, you can see different options available under Universe Design tool user interface. It has both the "Universe" pane” containing objects and classes usually visible in Web Intelligence/Dashboard designer tool and the "Structure pane" which is only visible in Universe designer.

  • Universe Pane
  • Structure Pane

In Universe pane, you can further expand each of class to see objects created in it. These objects are named as per business requirement and easy to understand for business users.

In Structure pane, Universe designer drags table and join them to create a schema. This schema view is only visible to Universe Designers and not to business users.

To connect to a data source, connection wizard is used in UDT and you can create multiple connections in UDT however each universe is created using single connection.

Universe design tool provides a graphical interface that allows you to select and view tables in a database. The database tables are represented as table symbols in a schema diagram. You can use this interface to manipulate tables, create joins that link the tables, create alias tables, contexts, and solve loops in your schema.

The following schema types are supported:

  • Star Schema
  • Snowflakes schema
  • Multiple Star schema

Universe are stored in CMS repository and user connects to universe using a web browser. When user connects to Universe, he can access all the data in a database.

Creating, Editing and Saving

A Universe Designer usually performs the following tasks −

  • Conducting user needs analysis

  • Designing and creating the Universe

  • Distributing the Universe

  • Maintaining the Universe

Let us see how you can create a Universe on a BEx query and publish in repository to be used for BI reporting. In the coming section, screenshots are included for easy understanding.

To create a new connection, click on File → New button.

New Button

You have to enter the Universe name and click on Next button. You can also use an existing connection from repository using drop-down list.

  • Description − This is used by Web Intelligence users.

  • Unique numeric ID − This number is assigned in CMS to identify Universe when it is first exported to CMS.

The following connection types are available −

Personal

Personal connections are not used to build and distribute universe in BO environment. They are unsecured connections and available to the creator and on computer which it is created.

Shared

Shared connections are unsecured connections and also used for data access to all users.

Secured

Secured connections are used to control data access and they are created using Universe design tool. You should use secured connection if you want to distribute Universe using CMS. You can also set a password on any Universe built on a personal or shared connection.

To set the password, navigate to Tools → Options → Save tab.

Secured

Enter the password in the Protection Password or the Write Reservation Password text boxes. You can enter up to 40 alphanumeric characters → OK.

SAP Universe Designer - Creating Schemas

A graphical representation of tables and joins organized to create a database structure is known as schema. Table used in schema contains columns which are mapped to object names in Universe which are used by business users to create reports and analysis dashboards. Schemas are created in structure pane using tables from target database. Tables are added to schema using table browser.

A schema in structure pane usually looks as below −

Structure Pane

Following stages are there in a schema design −

  • Inserting tables and organizing
  • Setting up table joins and cardinalities
  • Fixing join issues: loops, chasm traps, and fan traps
  • Performing integrating test of schema

When you drag a table from table browser to Structure pane, you can see all columns and their data types. When you drag tables, you need to set up table joins and cardinalities.

Table Browser

Syntax for calculated measure is shown below −

<EXPRESSION></EXPRESSION>

In UDT, you can use following functions to be used in calculated measure expression −

  • @Prompt
  • @Select
  • @Variable
  • @Where

To create an OLAP Universe, use the following steps −

In UDT, open an OLAP Universe and insert a new measure object in the Universe.

OLAP Universe

Next is to pass the object definition as an XML/MDX expression in Where condition.

Click Parse to review the object definition and fix any errors → OK to save the object definition.

To perform an integrity check, navigate to Tools → Check Integrity. The integrity check validates the XML syntax and any Universe design tool @FUNCTIONS.

Functions

SAP Universe Designer - Aggregate Awareness

In UDT, you have an option to run query against the aggregated tables in database. A condition can be set, and that query will run against aggregated tables for query optimization. This method of using aggregated tables is known as aggregate awareness.

To use aggregate awareness in Universe, you can use a function called @Aggregate_Aware in “Select” statement for an object that directs a query to be run against aggregate tables rather than a table containing non aggregated data.

To use aggregate awareness in a Universe, you need to arrange objects by aggregation level and objects are built using @aggregate_awareness function. To build aggregated aware objects, you need to first identify the objects: measure or dimension objects. You need to find out all possible combinations of aggregate objects in all tables and then arrange them in aggregate level order.

For example −

  • AAYEAR.Profit is the highest level of aggregation.
  • AAQTR.Profit is the next level.
  • AAMONTH.Profit is the lowest level of aggregation.

Using @aggregate_aware function directs an object to query all aggregate tables as its parameters. You can see an object using @aggregate_aware function in “Select” statement −

Aggregate Aware Function

The syntax to be used for aggregate_aware function is as follows −

@Aggregate_Aware(sum(agg_table_1), ... sum(agg_table_n))

Pass the names of all aggregated tables as arguments. Agg_table_1 is aggregate with highest level of aggregation and agg_table_n is aggregate with lowest level of aggregation.

Defining an Object using @aggregate_aware Function

Open edit properties dialog box for the object → Click “>>” button next to the dialog box.

Defining Object

In the "Edit Select Statement" dialog box, you need to click at the beginning of the SELECT statement.

Alternately, click anywhere in the select box if the object does not have a SELECT statement.

Sales Revenue

You can see @aggregate_aware function under list of functions on right side. As per description of this function: “@Aggregate_Aware(sum(aggregate table1),...,sum(aggregate tableN)) Defines a measure object using precalculated aggregate tables”.

SAP Universe Designer - Deploying Universe

When a universe is deployed, you make it available to Web intelligence users for reporting. Universe are deployed when they are exported to CMS repository. When a Universe is exported to CMS repository, a unique system identifier is assigned by the CMS.

To make Universe available to all designers, you have to check if the Universe is not built on a secured connection. Secured connections are used to export Universe to CMS repository.

To save Universe for all users, go to File → Save As or use F12.

Save As User

Select the Save For All Users check box → Click OK.

Saving Universe

To export a Universe, go to File → Export. You need to select the target Universe domain and a group. If someone else is using Universe, it will be showed as greyed locked. You can double click to lock/unlock a Universe.

Managing Access of Universe

You can manage Universe security either in CSM repository or in Universe level. For Universe in CMS, you can define users who can edit and delete based on access rights assigned to their user group. At the Universe level, you can define users who are allowed to use a particular Universe.

The following security level is applied −

CMS From the Central Management Console you can set restrictions that apply to universes stored in a CMS. You can set what universes users can access, and depending on the rights defined for a user group, you can restrict viewing, editing, deleting, and other actions in a universe. This guide does not cover setting restrictions at the CMS level, see the BusinessObjects Enterprise Administrator's Guide for information on using the Central Management System.
Universe You can define restrictions for users allowed to use a universe. A restriction can include object access, row access, query and SQL generation controls, and connection controls. This guide de-scribes the types of restrictions you can define on a universe.

Access to Universe are managed using restrictions and you can apply multiple restrictions to single dashboard. You can also edit and delete restrictions as per access requirement. The following restrictions can be used −

  • Connection − You can provide an option to use an alternate connection to data source.

  • Query Controls − This restriction can be used to limit the size of result and execution time of the query.

  • Access to Rows − With the use of Where clause, you can limit the result set returned and access the rows.

  • SQL Generation Options − This is used to control generated SQL from query.

  • Referencing Different Table − You can set a restriction to replace a table with another table in database.

  • Object Access − This restriction is used to allow users to select objects which are not used in the Universe.

To manage access restrictions, navigation to Tools → Manage Security → Manage Access Restrictions. The dialog box appears.

Manage Security

The current restrictions which are applied to Universe are available under available restrictions column. You can find users and user groups that are defined for each restriction under Available Groups and Users pane.

Note − Restrictions can only be applied to Universe which are exported to CMS repository.

Manage Acces Restriction

To add a user or group, click on add user or group button. In next window, you can see list of all available groups/users that can be added to restrictions.

Group Button

You can also define groups with highest priority of restrictions. Click on Priority button and restriction on group name with highest priority will take precedence.

UDT vs. IDT Comparison

Both Universe Design tool and Information Design tool are a part of SAP BusinessObjects client tool. In older version of SAP BusinessObjects BOXI R3, BOXI R2, UDT was only tool to create semantic layer between database and reporting tool.

In BO 4.0, IDT was first introduced that allows the use of multisource enabled Universe for reporting. Prior to IDT, the only option to create multisource enabled Universe was the use of linked Universe. Linked Universes are used to share common components such as parameters, classes, objects, or joins from different data sources. From BO 4.x, both IDT and UDT are part of SAP BusinessObjecs client tools.

Business Objects

Key differences between UDT and IDT

In UDT, Universe are created with file extension as .unv. In IDT, Universe file extension is changed to .unx file. To open unv file in IDT, it cannot be directly opened, however, you can convert unv file to unx file to open in Information Design tool. You cannot open an IDT .unx file in Universe Design tool and cannot convert it to unv file.

Universe Design tool is single source enabled. IDT is multi source enabled which means the data can be extracted from different data sources while creating a Universe.

Universe Design Tool (UDT) Information Design Tool (IDT)
Universe file extension - .unv Universe file extension - .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 multisource 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

SAP Universe Designer - unv File to unx File

To convert a unv file to unx file, you can use Upgrade Management tool UMT or it can be directly performed in IDT. First login to Information Design tool, and go to File → Convert .unv Universe.

Convert Unv File

You can select unv file saved in repository or on local folder. Once you connect to BO repository, you can find all Universe published to repository in the left pane.

Left Pane

In the next window, you have an option to select conversion parameters. Select the available checkboxes which are suitable as per requirement → Convert button.

Convert Button

Once conversion is done, under status column, you find “conversion done” message. You can also change the destination folder to save .unx file under Destination field. To select another Universe from repository for conversion, you can click on Universe icon located at the right side as shown below −
