Question #7: A, C
Once the info cubes are compressed it is not possible to delete data based on the requests. There won't be request IDs anymore.

It is possible to delete requests from an ODS, even if the request has been activated. The "before and after image" of the data will be stored in the change log table using which the request will be deleted.
Deleting a request which has not been activated in ODS will not delete the requests which are loaded after this request. But if the request has been activated then the loaded and activated requests later will get deleted. Also the change log entries will be deleted for that request.

Question #1: A, C, D
Master data and hierarchy data changes are activated and all the aggregates which have navigational attributes which will be affected by the changes are realigned. Change run deletes all active records for which modified records exists in master data 'P' table and makes all modified records to active.

Question #2: A
If an aggregate contains key figures which are built as MIN or MAX, that will force a change run to recreate these aggregates during the alignment process.

Question #3: B, D
Unless specified using transaction RSKC, special characters cannot be loaded into BW fields where it needs to generte SIDs. So it is possible for these characters to be loaded into text fields.

Question #4: B
A change run doesn't update the 'E' table of the aggregates for the alignment of aggregates due to master data changes. The alignment is done by inserting rows with the necessary negative and positive key figure values in the 'F' table.

Question #5: B
In the table ROIDOCPRMS, MAXSIZE is the size in kilobytes which is used to calculate the number of records in each datapacket to be transferred to BW. If the calculated number of records exceeds MAXLINES, the packet size in terms of number of records will be made the same as the value of MAXLINES value.

Question #6: B, C
A Multiprovider can be built on basic InfoCubes, ODSs, info objects or Infosets. An Infoset can have only ODSs or info objects. Multiproviders use 'union' operation but Infosets use 'join'. Both the objects are logical definitions which don't store any data.

Question #7: A, C, D
Transaction RSRCACHE is for the Cache Monitor. The OLAP Cache will be active unless the 'cache inactive' flag is set. Persistent mode is to specify the action to be taken when the cache memory is exhausted.

Question #8: A, B
If the BEx Reporting flag is switched off than the SID won't have to be taken when activating the ODS. This improves performance. If the 'unique data records' flag is set, it is not possible to load records to the ODS for which the key combination already exists. Data targets can be updated only after the ODS activation takes place successfully.

Question #9: B
It is possible to activate an ODS which contains Delta and full loads from the same InfoSource if the full load is done with the repair flag set in the InfoPackage.

Question #10: A, C
All data can be set to be deleted from a basic cube during full loads and Delta loads. Data can be deleted depending on various conditions. Data can only be deleted from basic cubes, not the ODS.

Question #11: A, C
Multiprovider queries create processes to run on the individual info providers involved. These processes run parallel by default. The parent process provides a synchronization point to collect overall results from sub processes. Many times the parallel processing may be slower than sequential processing, if the data volume is high.

Question #12: A, D, E
The ALPHA conversion routine is assigned to the characteristic info objects when created. This needs to be deleted manually if not required. The conversion is applied to 'external to internal' formats and vice versa. For 'external to internal' formats, the values are right aligned and the spaces on left side is padded with zeros.

Question #13: A, B, D
Queries using navigational attributes will be slower since additional tables have to be joined with the Fact tables to get the desired results. If there are changes to the values of navigational attributes, the aggregates using these will have to be readjusted, which is done by a change run. Navigational attributes can be made to display only without removing the data from the cube.

Question #15: E
The 'F' Fact table is partitioned on request and is created during data loads. The 'E' Fact table of the InfoCube is created with the number of partitions specified in the partitioning range. Once the data is loaded to the cube, partitioning based in the Time characteristic is not possible without removing the data. PSA table partitions can contain more than one request.
