We use the periodic average costing method for a while. Now we find a problem, the accrual value is difference between po receipt and ap.
For example, we did a po receive transaction in Feb. 01, price 1, quantity 10, currency rate is 10 in that day. Then we get the invoice in Feb. 20, the rate is 11, price is 1 and quantity is 10 also. The matching method is match to receipt.
After we ran the 3 pac programs, the accrual value in PAC is 110(1 price * 10 quantity * 11 AP rate). But the accrual value is 100 in AP(1 price * 10 quantity * 10 po receipt rate). The accrual is not balance.
