Question 1 :

We choose option Accruals at end period.

We use only non-inventory item.

We would like to have only one (item) distribution in case of invoice price variance with the PO.

Is it possible to do that ?

Currently, in case of price variance, we get two distribution on AP invoices :

Item : for the amount of the receipt matched

Invoice Price Variance : for the gap between invoice amount and PO amount
