S4: Customizing not active after import - table buffer issue

[Roland_J]

There is a problem in transport management on a SAP S/4HANA 2020 landscape hosted on Hyperscaler (private system).

Problem:

• SAP Transport is released in the dev system, contains customizing of a maintenance view.
• Transport Is imported in Q or Prod, but the customizing is not active after import.
• Although the entries are changed in the underlying table (check in SE16H), they still appear unchanged in the view. The system contiues to behave in a way, that new customizing is not active.

The remedy is to manually reset all table buffers (/$SYNC), a system reboot will do the same.

I do not have this issue with other customer so much, so this must be a system setting? Basis Team cannot find the root cause. But we do not have this problem at all/other customers... so there must be some setting in the system?

Sounds like the buffer synchronization is not working properly... that is a must because configuration tables almost exclusively rely on the buffering mechanism.
