If special characters are not defined in transaction RSKC in BW then:

  1. These characters cannot be loaded into BW at all.

  2. These characters can only be loaded into text fields.

  3. These characters can be loaded into attributes and texts.

  4. BW won't be able to generate the SIDs for these characters because all the fields where SIDs are generated cannot be loaded.

  5. None of the above.

Correct Option: B,D
  1. The field MAXSIZE is the maximum number of records which can be transferred to BW in a single packet.

  2. The field MAXSIZE is the size in KB which is used to calculate the number of records per data packet.

  3. MAXLINES is the maximum number of records which can be transferred to BW per data load.

  4. If the number of data records per packet exceeds MAXLINES value the extraction process fails.

Correct Option: B
  1. Both Multiproviders and Infosets can contain all the info providers in BW.

  2. Queries built on Multiproviders use 'union' and queries on Infosets use 'join' to retrieve data from different info providers.

  3. Both Multiproviders and Infosets do not have data, but data is accessed from the basic info providers used in these objects.

  4. None of the above.

Correct Option: B,C
  1. The transaction for the OLAP Cache Monitor is RSRCACHE.

  2. If the persistent mode is inactive then the cache is inactive and query results will not be cached in memory.

  3. A 'read flag' is set in the Cache Monitor when data is read from the cache.

  4. When new data is loaded into the info provider which the query is built on, the cache for that query is invalidated.

  5. All of the above.

Correct Option: A,C,D
  1. Performance of the ODS activation improves when the BEx reporting flag is switched to off.

  2. Overwriting a data record is not allowed if the 'unique' data record flag is set.

  3. Data targets are updated from the ODS regardless of the ODS activation status.

  4. All of the above.

Correct Option: A,B

  2. Only uncompressed data can be set to be deleted from the cube in an InfoPackage during the loads.

  3. Deletion settings can be done only for basic InfoCubes.

  4. Data deletion settings in an InfoPackage are possible only for full loads.

  5. All of the above.

Correct Option: A,C
  1. Multiprovider queries create one process per info provider involved and are processed parallel by default.

  2. It is not possible to make Multiprovider queries run sequential.

  3. Multiprovider queries create a parent process which provides a synchronization point to collect the overall result from other sub processes.

  4. Parallel processing is always faster than sequential processing in Multiproviders.

  5. All of the above.
