Hello,
Thanks for the feedback.
The idea behind the manipulation that I recommended, is that the EHP4 for SAP ERP 6.0 instance SAP SEM on Netweaver 7.3 contains both SEM-BW 634 and FINBASIS 634. On the other hand, there is no product instance that has only FINBASIS 634.
FINBASIS 634 has only SAP SEM NW7.3 as possible product instance assignment
In conclusion: there is no software component lacking assignment or that will be ommited during the subsequent updates if you just don't assign product instance Finbasis.
As for Business Functions, the SAP Note 1165438 contains all the mappings between technical usages and business functions. Technical usage Finbasis is the technical usage that results in product instance Finbasis being installed. But, technical usage Finbasis has no business function mappings.
The only impact of removing product instance Finbasis from LMDB could be the removal of a system identity table entry for Finbasis. But that is metadata, not really any coding.
Best regards,
Miguel Ariño
