What all data sources are available?

BO allows us to review data from various sources. We can use data from RDBMS such as MS SQL server, Oracle, etc.

What is Visual Difference?

Visual Difference enables you to view the differences between two versions of a supported file type(LCM BIAR) or a supported object type(LCM Job) or both. You can use this feature to determine the difference between files or objects to develop and maintain different report types. This feature gives a comparison status between the source and the destination versions. For example, if a previous version of the user

report is accurate and the current version is inaccurate, you can compare and analyze the file to evaluate the exact issue.

Following are the three types of visual difference from which you can detect the file or an object:

  • Removed – In a report, if an element is missing in one of the file versions, the type of difference is shown as Removed. For example, the element could be a row, section instance, or even a block.
  • Modified – In a report, if there is a different value between the source version and the destination version, the type of difference is shown as Modified. For example, the value could be the cell content or the result of a local variable.
  • Inserted – In a report, if there is an element in the destination version but is not present in the source version, the type of difference is shown as Inserted.

Define personal connection?

It can be made only by one user and can’t be used by the others. The details for same are kept in a PDAC.LSI file.

Define Shared connection?

It is opposite of personal connection as it can be used by others also through a server which is common one. In this details of connections are kept in SDAC>LSI file which is there in installation folder.

Define secured connection?

It is a kind of connection which overcomes the disadvantages related with the former connection. We can use universe in central repository by secured connection.

What is custom hierarchies?

It defines the universe for providing the drill down which is customized and occur between objects from same or different classes taking care of the user requirements.

How we can create Custom Hierarchies?

We can create custom hierarchies by clicking on tools then choosing hierarchies from BO designer.

What do you understand by context in the universe?

Context can be explained as the specific path of join between a specific group of joins or the tables for the purpose of a specific query.

How we can create Custom Hierarchies?

  • The second one is involving two joints in different contexts.

Define Derived tables?

They are created in the universe. It is used for complex calculations which can’t be sorted out in the report level. The other useful feature of derived table is that by using dblink we can use the table from other schema.

What is User Objects.

It is a universe of classes and objects which is developed by the universe designer. Once the objects which is there in the universe does not matches our requirement, then the user can create his own objects which is known as User objects.

@derived_table(derived table name)

What is Slice in Business Objects.

It is used to reset, rename and omit the blocks. It works with the master or detailed reports.

Differentiate between Dice and Slice.

  • Dice: It shows the data and removes the data.
  • Slice: It reset, rename and delete the blocks.

Define master/detail report?

Big block of data can be break into small sections by using master or detail report. Replication in values can be avoided by using this.

What is class?

Collection of objects in a universe is known as class. Subclasses are derived from the class.

What is aggregate_awarness?

We use aggregate_awarness function to define one object for measures in fact tables when we have a same fact tables in different grains, the syntax is as,
@aggregate_aware(highest_level.lower level)

What is fan trap?

A one to many join links to a table which answer with another one to many join links is known as fan trap.

What is Data provider?

The question or the data source is known as the data provider.

At what time we use a context?

Context is developed when the dimension objects are their in one or both fact tables.

What is Auditing in BO 4 ?

Auditing allows you to keep a record of significant events on servers and applications, which helps give you a picture of what information is being accessed, how it’s being accessed and changed, and who is performing these operations. This information is recorded in a database called the Auditing Data Store (ADS). Once the data is in the ADS, you can design custom reports to suit your needs. You can look for sample universes and reports on the SAP Developer Network.

For the purposes of this chapter, an auditor is a system responsible for recording or storing information on an event, and an auditee is any system responsible for performing an auditable event. There are some circumstances where a single system can perform both functions.

What is Monitoring in BO 4 ?

Monitoring allows you to capture the runtime and historical metrics of SAP BusinessObjects Business Intelligence platform servers, for reporting and notification. The monitoring application helps system administrators to identify if an application is functioning normally and if the response times are as expected.

Monitoring allows you to:

  1. Check the performance of each server
  2. Check system availability and response time
  3. View the entire BI platform deployment based on Sever Groups, Service Categories and Enterprise nodes in graphical and tabular format.
  4. Check health of server

What are tables available In CMS database in BO ?

There are 6 tables on the database level to store the metadata.

  • CMS_VersionInfo
    The table contains the current version of BOE.
  • CMS_InfoObjects6
    This is the main table in the repository. Each row in this table stores a single InfoObject. The table contains the following columns: ObjectID, ParentID, TypeID, OwnerID, Version, LastModifyTime, ScheduleStatus, NextRunTime, CRC, Properties, SI_GUID, SI_CUID, SIRUID, SI_INSTANCE_OBJECT, SI_PLUGIN_OBJECT, SI_TABLE, SI_HIDDEN_OBJECT, SI_NAMEDUSER, SI_RECURRING, SI_RUNNABLE_OBJECT, SI_PSS_SERVICE_ID, ObjName_TR, SI_KEYWORD, SI_KEYWORD_TR, LOV_KEY.
  • CMS_Aliases6
    This table maps the user alias(es) to the corresponding user ID. A user has an alias for each security domain in which they are members. For example, a user may have both a Win NT alias and an LDAP alias. Regardless of the number of aliases a user may have, in the BI Platform each user has only one user ID. The map is stored in a separate table to enable fast logins.
  • CMS_IdNumbers6
    The CMS uses this table to generate unique Object IDs and Type IDs. It has only two rows: an Object ID row and a Type ID row. The CMSs in a cluster use this table when generating unique ID numbers.
    GUIDs, RUIDs and CUID are generated with an algorithm that does not use the database.
  • CMS_Relationships6
    Relationship tables are used to store the relations between InfoObjects. Each row in the table stores one edge in the relation. For example, the relation between a Web Intelligence document and a Universe would be stored in a row in the WebI – Universe Relation table. Each relationship table has these columns:
    Parent Object ID,Child Object ID,Relationship InfoObject ID ( this Default InfoObject “DFO” describes the properties of the link between the two objects.), member, version, ordinal, data. Relationship tables are defined by default objects.
  • CMS_LOCKS6
    This is a auxiliary table of CMS_RELATIONS6
