Business Objects (BO) Interview Questions [Part # 1]


1) What is alias table means? When we should use it & how to create it?

Alias Table: Is a copy (alias) from a database object. 
When to use it: we normally create an alias if we have one dimension shared among more than one fact table. to avoid loops we create as many aliases from the shared dimension table and use aliases to connect to fact tables.
How to create it? Right click on the required table and select alias from the menu. You need to give a unique name to alias table.

2) What is Derived table? When shall we use it? How to create it?

Derived table: is like database view. you can create it inside universe designer if you don’t have database privilege to create database view.  You need SQL select query to define the view and name to be assigned to derived table.
When to use it: We use derived table in the following cases
  • You have complex query with advanced SQL coding.
  • if you have one master lookup table and you want to create small customized version for each lookup included in this lookup table.
How to create derived table: right click in an empty place in foundation layer [physical layer] in sap BO universe designer and select derived table from the menu. Enter a name for the derived table & SQL query to define the table.
for more detail information check this link [Derived table in SAP BO]

3) What is Scope of Analysis?

Scope of Analysis is one of the most powerful features in business objects. Now you can easily build your custom hierarchies and use them in your report to navigate through data. To make it easy I will consider a small example then go step by step starting from building the universe and end with how to use the drill feature to navigate through data.For more detailed information check this link [What is Scope of Analysis?]

 

4) What is Micro Cube in SAP Business Objects

When you create data query in SAP business Objects the data retrieved and stored in a Micro cube, known also as Webi micro cube. This Micro Cube is stored along with the report and the report size will vary based on the saved micro cube size. BO reporting engine will use this microcube to display data on the report based on the selected objects and based on the aggregation function associated with each measure. to reduce the micro cube size you need to assign database aggregation function on each measure. This will submit a grouped by query to the data base and it will reduce the micro cube size and it will enhance the overall report performance. For more information check the following link [Micro Cube in SAP BO]

 

5) What is aggregate aware function? when to use it?

This function used to increase the performance by directing the report query to select objects form the aggregated table instead of the detailed table.
It may be also used to make some objects incompatible with some others. The best example for such case is the stand alone table that you add in your universe for a specific report. For sure you don’t want the user select other incompatible objects from other incompatible tables. for more detailed information check this link [@Aggregate_Aware()]


You can find a complete step by step guide on how to create a Universe from scratch using SAP BO information Design Tool in "Creating Universes with SAP BusinessObjects" book:

Prompt in SAP Business Objects WEBI Report

Introduction:

There is 2 types of filters that you can use in create query in your Webi report.

Static Filters: Doesn't need any interaction from the end user. the criteria or filter values are impeded inside the filter and will submitted directly to the database. Static filter is either created in the universe and you can just drag and use them. They will appears like a yellow cone. You can also create your own static filters by dragging an object and set you filter values to constant or select from list of values. Again, when you refresh data fro your report it will not ask the end user to enter any values as the filter values already defined.

10-22-2013 1-21-50 PM

Dynamic Filters: [Also known as prompt] It will prompt or ask the end user to enter or select filter values before submitting the query to the database. You can create your prompt in the universe designer and make it available and ready for use or you can do it on the report development time. For more information about how to create prompt in universe click here.

To create a prompt in info view or rich client data query just drag the object that you want to use it as a prompt let say Region or Product for example. Then select the required operator, let’s say Equal to or greater than. After that you need to select Prompt in the filter value.

The following window will displayed to set the prompt the following prompt options:

 Prompt Text: Enter the text that will be displayed for the end user to ask him to enter or select value.

Prompt Properties:

Prompt with list of values: Will display a list of values for the selected object to the end user. the end user will be able to select one or multiple value instead of entering them manually.

Keep Last Value selected: Will keep the last value entered by the end user selected.

Select only from list: end user will not be able to enter any data manually and he will just forced to select from the list of values. of course this option will be enabled only of we selected the prompt with list of values option.

Optional prompt: If this option is selected the end use will be able to skip this prompt. the value will be considered only if the end user selected a value for this prompt.

Set Default Values: You can enter Default values here.

10-22-2013 1-24-06 PM

Best Practice:

“As you can create static and dynamic filter in the universe you need to differentiate between them. we used to write [Filter] beside the static filter name like: Last Year [Filter]. and we use the “?” at the end of filter name if it is a dynamic one [Prompt] like: Enter Year ?”

“Choose a clear prompt message”

“If you will use the prompt with list of values option then you have to optimize it from the universe to insure the performance”

CORBA Initialization failed. (WIS 10901) error in WebI Rich Client

 

Today we faced a power frailer in our building. I was using Rich client and logged in by user name & password. After My PC was restarted I able to do the following:

  • Login to rich client.
  • Navigate to a Webi report and open it in rich client.

When I tried to refresh any report from Rich client I got the following error Message:

Query Name – Universe Name

A database error occurred. The database error text is: (CS) “COBRA Initialization failed”. (WIS 10901)

Error Message:

Code: WIS 10901

Error Message: A database error occurred. The database error text is: (CS) “COBRA Initialization failed”.

Application: Rich Client

Environment: BO XI3.1

 

Notes:

  • You will be able to refresh the data in the same report If you tried to login to info view and refresh it from there.

 

Resolution:

Resolution Method # 1: Don’t log to the JR2 system. Log into the original one. The error message will be displayed if you tried to login to the system beside the (?)

Create data query in business objects WEBI

 

In order to ask for data retrieval from Database or any support data source by business objects you need to create a query in your report. In this query you have to identify what you want to include in your report and you will define query filters as well to narrow the returned data results. If you are familiar with SQL then you will not find any troubles to understand this section. If no then you will learn SQL select statement as well as how to create query in SAP business objects WEBI.

SQL select statement:


the simple SQL statement should contains at least the following SQL clause Select-From-Where. After select clause you should enter the data that you want to display and retrieve from database. In the from clause you have to specify from which tables. And in the where clause you need to set you filters. Lets take an example

Select Statement Syntax:

Select {List of columns that you want to display}

From {List of tables}

Where {Criteria to narrow the number of returning records}

Example:

Select employee_Name, employee id
From employee
Where employee grade =A

Create Data Query in BO WEBI Report:

Now check the data query window below. you can easily find that it almost the same concept & logic. Your available data listed in the left panel. As you can see it is grouped in folder as per their business meaning and relation. you can also differentiate between dimensions, Measures & detail objects. On the right hand side you can see the select area as well as the where or filter panel. To create a query simply drag and drop data from the left side panel to the select area. if you want to create a filter, then you need to drop your object in the where are instead,

Finally to run the query just click on the refresh data button.

Create query tutorial

Find below a step by step user guide and tutorial with examples on how to create a data query in SAP business objects Webi report. Please note that this apply to rich client as well as info view.

To create a new query in your report go to data or click edit query button. The following window will open

Create Query # 1

We can classify work area here into 4 main panels

Upper tool bar:

Show hide filter ban: This icon will hide or show the filter ban. Filter ban is the area that represent the Where clause in SQL select statement and it will contains your criteria that will be used to narrow the number of returned records or to only retrieve the data corresponding to your analysis.
Show hide scope of analysis: This will show/ Hide your scope of analysis area. for more information about scope of analysis please click on the following link.
Show / Hide data manager: This icon will show or hide data ban which contains all available data based on the selected universe. We will talk about this topic in details in a moment.
Add Query: This button will create another query. You can create as many queries as you can in your report. you can use the bar at the bottom to navigate through the created queries. Please note that you can include data queries based on different universes in the same report.
Combined query: This icon should be used to create a combined query. Combined query is an advanced query that use the union-intersect or minus. Please note that combined query can be tow or more queries. The only restriction here is that combined queries should be from the same universe.
SQL: If you click on the button you will be able to see the SQL code generated by the report engine to be sent to the database engine to retrieve the required data.

Create Query # 2

Left panel


Data Business model: this panel will display a categorized list of all objects available based on the selected universe. You can drag and drop dim measures and filters as well or simply double click on them. You can use search feature to look for a specific object by name. You can change the display for the data by selecting one of the following options from the bottom:

  • Display by object.
  • Display by hierarchy.


DataHier

Properties: from the properties panel you can access the following options:

  • Query Name: You can type a meaningful name for your query here. the default query name is “Query#” where # is the current number of created queries in the current report.
  • Universe: You can even change the universe from here.
  • Limits: You can limit the number of records returned by your query by set one of the following options or both: Max rows retrieved or Max retrieval time. Usually we use this option during development time if the number of the returned records is huge. this will help us to test the functionality of the report and to focus on the layout. later one we can disable them when we are on UAT and production stage.
  • Prompt order: You can change the prompt order from here.

 10-22-2013 1-25-32 PM

Right panel

Select Area: Here you can drop your objects that you want them to be part of your analysis.

10-22-2013 1-18-20 PM

Where Area: Here you should drop your query filter or create them. Pre-defined filters know as conditions are previously created in the universe and you can just drag and use them. on the other hand you can create new customized filter as per your need.

Normal filter will contains the following:

  • Object: The object that you want to filter one
  • Operator: Equal to, greater than, less than,….etc
  • Operand:
    • Constant
    • Value from list
    • Prompt
    • Result from another query(Any)
    • Object from this query


10-22-2013 1-19-06 PM10-22-2013 1-21-50 PM

Scope of analysis Area:

In Scope of analysis area you can customize your hierarchy levels to be used in the drill down analysis. for more information about what is scope of analysis please check this link

10-22-2013 1-24-36 PM

Bottom Bar:

You can manage your queries from the bottom bar. if you right click on this bar you will able to see this menu: You can use this menu to rename query or to run a query, duplicate a query or add a new one.

10-22-2013 1-16-33 PM

You can use the bottom right arrows to navigate or order queries.
