So you mentioned it will hit the accrued accounts. Does the 20001 somehow correlate with the 23001 accrued account? Or if I set the

Default Expense Account

on the vendor record, would that set the credit on the IR? (I will try it now)

Im not sure what u r looking to do with an expense account. But when u recieve through an IR what u r doing is recognising any inventory thats in you warehouse, pending billing hence Accrued purchases, this account acts as a clearing stop for inventory to see if all the inventory is billed accordingly. Once we bill the PO. This clearing will close and A/P will appear on your balance sheet.
