How to handle Inventory Cube compression and conversion to Hana Optimized Cube on BW/HANA 7.5 for a Scale-Out System
- Inventory Info-Cubes still contain uncompressed, delta movement, requests.
- Compression doesn’t work anymore after migration to BW on Hana 7.4 for multi-node (scale-out) systems.
- Conversion process (RSMIGRHANADB) fails for these Inventory Info-Cubes due to uncompressed requests.
XXXXXX – Inventory InfoCube.
The current state is that the system is already migrated to BW 7.4 on HANA SP10 and the Inventory Info-Cube still contains few uncompressed requests.
These are delta movement requests. No historic movement’s requests.
Although the system is migrated, the Info-Cube is still not converted to HANA-optimized.
We also make sure that this is an Inventory Info-Cube with non-cumulative measures (Key figures):
First attempt to convert to HANA-Optimized Info-Cube:
System issues an error message stating that the Inventory Info-Cube must be fully compressed before the conversion.
Therefore, we attempted to compress the requests in the Info-Cube:
Unfortunately, compression is no longer possible and system issues an information message that
No compression possible for Standard Info-Cubes in scale-out (multi-node) HANA systems:
Searching, we found the SAP Note -1773398 confirming this limitation in a BW on HANA scale-out landscape.
Therefore, even though the job completed successfully, it didn’t compress the request.
First, we checked if the entry already exists in the RSADMIN table or not.
To insert the parameter, execute program: SAP_RSADMIN_MAINTAIN
Set the below parameters:
Now, we attempted to compress all the requests, one by one, and it completed successfully!
All requests successfully compressed:
Lastly, we attempted to convert the Info-cube to HANA-optimized and it completed successfully !
We checked and found that the InfoCube is now HANA-Optimized:
The Cube have been converted to Hana optimized cube with all the requests compressed.
