Purchase orders and partially received shipments

[Charley Tiggs <..hidden..>]

I've finally had some time to pay attention to some odd behavior that 
showed up in 1.2.6 that wasn't present in 1.2.5.  Today, I got enough 
additional information to finally know where to look.

In 1.2.5, I could do the following:

1) Create a purchase order with several widgets on it, 10 each.

2) Receive five each of those widgets against that PO via 
Shipping->Ship->Receive

3) Find the purchase order via Order Entry->Reports->Purchase Orders and 
click on the "Vendor Invoice" button.

4) Post the invoice (without paying).

5) Search for the same PO and the original PO is still open as there are 
still items that need to be received in.


In 1.2.6 and beyond, the behavior changed after step 2:

3) Find the purchase order via Order Entry->Reports->Purchase Orders and 
click on the "Vendor Invoice" button.

4) Post the invoice (without paying).

5) Search for the same PO and the original PO is closed and a new one 
has been created for the remaining amount due.


This is a little confusing for the warehouse doing the receiving.  When 
they go to look up the numbers they have received, they see two purchase 
orders, one of which is only partially received and the other has 
nothing received against it.  They can't tell in any way whether the 
second purchase order is an order that was tacked on to the original or 
if they should ignore the original.  At any rate, it makes it difficult 
for the person doing the receiving to figure out what has already been 
received against that purchase order.  This client has instances where a 
PO may be received against 5 or more times since they order large 
quantities of items and expect to receive them in installments.  A 
search for such a purchase order would be tedious to manage in terms of 
finding out when certain items where delivered.

So, is this a bug?  If it's not a bug, can someone explain the logic 
behind having purchase orders behave this way?

Thanks,
