The system posts GL transactions for an adjustment to standard cost in the official daybook for standard inventory transactions. When you select the option to create an adjustment to standard cost, the system posts periodic cost-calculated transactions initially to the transient daybook and layer and subsequently transfers the costs to the management daybook and layer during the month-end close process as a basis for the adjustment to standard costs.

Before moving transient daybook entries to the official or management daybook for the current period when posting periodic costs or adjustment to standard cost to GL for the current open period, the system ensures that IC and WO transactions are closed in the current GL calendar period. Also, the current open calendar period should be closed to additional periodic cost recalculations and GL transaction creations once the system posts final periodic cost GL transactions. This should be done for all entities (in the domain) in the range of the calculation.

The system generates a receiving GL transaction for purchase order receipt and return inventory transactions.

During month-end closing when the system moves final posts from the transient to the official layer, the system does not generate RCT-PO GL transactions again because they are already posted to GL. This means that it is not necessary to reverse PPV and AP variances because they are posted as inventory accounts.

The month end close does not cause the system to resend these figures by period cost because they are already in accounting. When creating an adjustment to standard GL based on the periodic cost calculation for the current period, the supplier invoice and actual PO cost are already created in GL so the receipt transaction is just the one for period costing.
