Corrections
To correct mistakes or make last-minute cost adjustments, you can redo the last period cost calculations. Since you can update unit cost per item per site, the system considers these transactions an inventory adjustment.
1 Reopen the previous period.
The system checks whether the open period is the previous period.
2 Choose one of the following:
Reverse an adjustment that you made, using one of the adjustment programs from the Periodic Costing Menu to adjust element or other costs.
Reverse a complete GL transaction.
3 Run Periodic Cost Calculation (30.5.7.1) on the reopened period, undoing the costs calculated for the reopened period.
