HI Miguel, Can you check RSPLSE and reply what you find there.
I was looking at the below info and I don't see anything changed in 7.4
Displaying Active Locks - Planning Business Data with BW Integrated Planning - SAP Library
If you want to delete active locks, use SAP lock management (transaction SM12). Depending on where the lock table is stored, you might have to select a different lock structure.
- Lock table on SAP lock server: Table name RSPLS_S_LOCK.
- Lock table in shared objects memory: Table name RSPLS_S_LOCK_SYNC.
- Lock table in SAP liveCache: Table name LCA_GUID_STR.
In SAP lock management (transaction SM12), you cannot see which data records are locked however. To do this, use the maintenance transaction for lock settings in planning (transaction RSPLSE).
Perhaps after the upgrade some security tasks might be pending, just wondering if you can try using ddic and let us know.
Thanks
