Ans: 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:

2. 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.

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.

Q69. What are tables available In CMS database in BO ?

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

1. CMS_VersionInfo
   The table contains the current version of BOE.
2. 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.
3. 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.
4. 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.
5. 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.
6. CMS_LOCKS6
   This is a auxiliary table of CMS_RELATIONS6
