Why is the Allow AP Bill Befor Receipt check box not enabled on Purchase Order Other tab?

​@dgodsill97 , the system applies the Allow AP Bill Before Receipt setting when the vendor is selected on the purchase order. The intent is to keep the behavior consistent for an order and to avoid situations where the flag is adjusted on individual documents, which can lead to errors or unexpected results.
If vendor invoices are received before the goods, the check box must be selected at the vendor level so that bills can always be entered before the receipt. 

Consistent behavior is nice but restrictive.  The process needs work. If you subsequently enter the PO receipt, it does not update the AP Bill with the receipt number. Neither does the Link action on the AP Bill Details - it finds the receipt, but it does not update the bill line.  A proper process would to allow the entry based on PO, but hold the bill by default (a status of Waiting for Receipt would be nice), and update the bill with the released PO receipt. 

A little background: the client does a very high volume of drop ship PO’s and wishes to import the bills from files provided by their vendors.  It seems the Add PO in an import scenario does not allow the quantity or cost override which is a problem and if we enter the transaction manually it does not flag cost discrepancies between the PO and bill.  

They will not pay the vendor until the vendor indicates the order has shipped and provides the carrier tracking number.  We have in place a business event to create the PO Receipt automatically when their external system indicates the shipping notice was received.  

Obviously, visibility is necessary as to the status of the PO receipt.

​@dgodsill97 it sounds like your scenario requires the ability to import or enter a bill first, link it to the PO, keep the bill on hold until the receipt exists, and then automatically link the released receipt to the bill so that quantities and cost differences are validated. This workflow is independent of the Allow AP Bill Before Receipt setting and would need to be addressed separately.

I would recommend creating a separate idea so that we can track it as a standalone improvement if there is no one yet.
