for HR ie Time and Payroll, Cluster Tables remain on HANA as well
its better to decluster them if you have reporting needs by using standard report and also activate switch
so Payroll is updated both in cluster and declustered tables, but both will remain and it doesn't go away if you move to HANA for HR
Somewhere SAP stated that cluster will remain even after HANA migration due to the need of huge reprogramming in case of getting rid of it. Declustering can be used on top, but must be activated.
Is there anyone else with some experience regarding cluster tables and HANA?
Hi Yvonne:
I am not sure if I understand your question correctly because the term "HANA" is used in a variety of senses and applies almost to every new product SAP is releasing... but maybe I can clarify your doubt if your question applies to SAP HANA database.
I am currently on SAP HANA DB...
Actually currently moving from an DB2 system to SAP HANA system.
For the moment I have a copy of my DB2 system in the SAP Hana instance... (or should have)
I see payroll result are still in the PCL2 table and declustered tables are empty. I have made a simulation of payroll, previous result are read correctly it seems..
My understanding is the declustered payroll result is necessary if you want to use new services such as the payroll control center but not really necessary if you stick to our old legacy transaction of calculating payroll, posting result to FI or any other old one that actually fetch the payroll result from the clustered tables PCL2. There is an option to activate the declustering and once activated the payroll result are pushed to both clustered and declustered table.
I have not yet started proper testing and adjustment so obviously I cannot be 100% sure but so far this is how it looks and feels...
Best,
Antoine
Just for your information:
We have migrated our sandbox system to HANA and everything is fine with our cluster tables - without doing any preparations.
It seems that what we call "cluster tables" in HCM are not really cluster tables in SAP because in SE11 these tables are transparent tables (before and after HANA migration).
