A/P Accruals are generated for each Voucher Charge associated with an A/P Voucher when the voucher has either not yet been matched to a freight bill detail, or has been matched to a freight bill detail where the corresponding freight bill has not yet been transferred to your external accounting application.
However, if the Approval Chain for Voucher Adjustments has been enabled globally, Voucher Charges are not eligible for the A/P Accrual process until the corresponding Approval Document has been approved. This is applicable regardless of whether the Accrual process is triggered during Period Close or by an A/P Accrual Run Request.
