Over the years we have seen issues where standard cost rollups are done, implemented and the revaluation journal created. The user does not immediately post or transactions occur while there are records in the journal. This will error our the revaluation posting and I have seen users end up not even posting the journal due to this issue which can create a costing / inventory valuation mismatch.
I would propose that if an item has a record in a revaluation journal, block posting for the item system wide until the inventory valuation journal is posted or records deleted.
I realize this can stop a lot of posting but the damage done by not getting the revaluation posted would be considered worse.
