IC Settings - First Period on Perpetual Integration / First Period on Periodic Integration

Navigator > Setup > Inventory Control > Settings > Integration tab > change Integration Basis > Save (F9)

When you change Integration Basis, select the first period to start the change from.

Any Transfers to GL for the selected period or later will be reset. Any IC sourced GL batches on or after the Period previously transferred should be unposted and deleted.

Note: That this only applies to Inventory Control so any processing already done in Accounts Payable for Stock Purchases on or after the period will require manual adjustment to use the correct GL Account.
