When billing purchase order, it didn't hit into purchase account that i set in item record. Please help

Billing a received purchase order will go to one of a couple places. Can you please add more detail on what you expected?

It is standard po and it has inventory in it. When item is received against the po. The ledger accrued purchase got credited. Is there away to make any other account ledger credit instead of accrued purchase

Oh. That's standard functionality. No you can't change that. You need to receive the PO to get your inventory impact first, and post to accrued purchases. Then your bill will move it from accrued purchases to accounts payable
