is there any security guide or any guide on how to configure LOPD witihn SAP BW? Tried to find sometihng but no success. Or should i just take a look at the BADI RSEC_LEGAL_AUDIT_SAP and try to figure it out on my own?
I just found a general documentation reg Data Protection and Privacy as part of Security Guide SAP BW∕4HANA:
Perhaps FAQ Note will be relevant for you:
