Urgent! Help on MMPI Error "Some material master records are locked."

[former_member1119016]

Please read the details below and kindly support to resolve the issue.

We proceed MMPI to reopen the previous period but it shows the error "Some material master records are locked. As a result, initialization is not possible"

This is not in the testing system but active system under 100.

We limited all user ID accesses to the system deleting all histories showed in SM12 when we do the MMPI except BACKJOB and IF user. Since this is under 100, not in the sandbox, we were concerning to delete all of them.

We also refer the notes no.487381 and 1082841 and followed all conditions of it.

No September material ledger occurred yet until tomorrow in the morning 6:30am, so we need to resolve this issue before then to meet the requirement of 'No Material Ledger Active' to reverse the period. Please carefully read the step that we did and advise the solution ASAP.
