Highlighted points:
Access possibilities on the raw data in BWA.

TREXADMIN in BW system in order to see raw data.
This an SAP information note.

This SAP note comes with an ABAP correction.
SAP Note: 1952887 - Virtual Infoprovider Indexing does not finish when data is read in packages

SAP Note: http://service.sap.com/sap/support/notes/18725011957532 – Database problems when loading a flat fact index into the BWA
Highlighted points:
The loading of a big InfoProvider is very slow. In the filling log (SM37) the delay happens already during the first read from the database. The transfer to BWA and the BWA itself is ok.
This SAP note comes with an ABAP correction.
SAP Note: 1958848 - BWA 7.20 rev30: Creation/Filling of temp indexes not python traced
Highlighted points:
There was a gap in the python tracing functionality: Operations on temp-indexes were not traced. (These temp indexes are automatically created if a BW-query uses a hierarchy selection (and if this selection was not used earlier already).)
This will be fixed with BWA 7.20 Revision 31.
SAP Note: 1965591 - BWA 7.20 rev29: IndexServer crashes or returns error 2999 when running a query with hierar...
Highlighted points:
The “Allstate issue” fix: With this correction the execution of SAP_DROP_TMPTABLES will really completely delete the temporary indexes (and not leave some hidden data structures undeleted which led to the problem).
Available from BWA 7.20 Revision 30 or later.
SAP Note: 1966774 - Incorrect query results when reporting against an InfoCube with a flattened BWA index
Highlighted points:
In BW 7.0x (only there) an error in BW can lead to an inconsistent Package dimension index and then wrong data from BWA.
Reloading the cube should fix the issue (temporarily).
This SAP note comes with an ABAP correction.

SAP Note: 1978566 - RSDDBIAMON2: index checks reveal meaningless variances for BIA-only InfoCubes
Highlighted points:
Comparison of F-table size (DataBase) and F-index size (BWA) makes no sense for a BWA-only Provider. So it gets
switched off with this note.
