We seem to have found that work order transactions can be
posted to the prior month even after the close date (30Sep04) has been set. We noticed a work order transaction posted on 30Sep04 done on 12Oct04.  The fiscal month end should prevent any operational transactions from occurring. Why did this happen?

On the brighter side, even though the work order transactions carry a prior month date in the Work Order Module, the prior month date can be manually edited to the current month using GL-P, and searching by date BEFORE posting these work order transactions to the General ledger.
 
This helps keep the integrity of the General Ledger to the current month, and not change prior month statements by others effecting transactions carrying prior dates.
