This entries created in the same period, and the PO cannot be closed because the output quantity still zero after returned journal. The average cost period is a "day" and average cost calc. type is an "item".
The step below maybe can help you to illustrate the problem :D
1. Ledger entry created after posted the output journal have an entry no. 264574 and the posted returned output journal entry no. is 265466
As you can see, the cost amount (expected) for both of line have differents amount.
2. If I click applied entries for entry no. 265466 it show like this
So it means that entry no. 265456 already applied to entry no. 264574
3. I have check item application entries too and it showed like this
We can see, for item ledger entry no. 265466 get the inbound item from entry no 264574. So it means that the applied entries is correct.
The big question still on the figure no. 1, why the cost amount (expected) have different amount although I have already applied it?
Thank you,
