Uses of Inventory Control period end dates
Inventory Control uses period end dates to control transactions sent to General Ledger. You can process transactions within 35 days (plus or minus) of the current period end date. The period end dates also are used to capture data for reporting and to calculate average inventory.
Inventory Control period end dates are used only in Inventory Control. These dates are not matched against the General Ledger calendar. If you use system control in General Ledger, then your dates are in sync because you are forced to close an Inventory Control period before you can close a General Ledger period. See the General Ledger User Guide.
