Request accounting accrual accounting

Hi,

Please assist, we use 3 way matching, there is a PO raised eg May19, the invoices was captured in Aug-19, and there was no receipt then. The invoice stays as Needs Revalidation status with the Qty holds, and Accounted in Aug19. The accrual raised was on Debit.

Then in Sep-19 the receipt was raised, the accrual was credited. The invoice status changed to Validated status.

My question is since the invoice accounting happens in GL period Aug-19, does it needs to change to period Sep-19 after the receipt is raised or when then the receipt is raised after the invoice, no accounting happens on invoice side, it only happens in Receipt?
