1730345 - SAP HANA DB: Cube migration may lead to corrupted data

Symptom
You convert a BW InfoCube to an SAP HANA-optimized InfoCube and afterwards you have NULL values in the fact table of your InfoCube.


Other Terms
SAP, HANA, in-memory, converting, InfoCube, cube, corrupt, wrong


Reason and Prerequisites
Prerequisite: SAP HANA DB Revision 31 or previous
Reason: Due to a programming error it can happen that you get NULL values in your fact table when you convert your InfoCube to an SAP HANA-optimized InfoCube if all of the following actions have been executed:
  • you have deleted requests in your fact table
  • "Reclaim Version Space" (an db internal action to prepare cleanup of deleted requests)has been executed
  • a delta merge of the fact table happened (is executed automatically by database on a regular basis)


Solution
Apply SAP HANA DB Revision 32 or later and rebuild the affected InfoCubes

Note: SAP note 1731569 provides a check to verify if one of your SAP HANA-optimized InfoCubes are affected by this issue
