Automate Fill/Kill for PO Lines

We've been JIT since 1998 but have always left Cancel Remaining up to the Buyer working their open orders. But you could build an IPA:
When PO Line Received Qty > 0 and < PO Line Quantity, then Change Cancel Qty to PO Line Quantity - PO Line Received Qty and CHANGE.
Run that nightly?

We currently use the YNQ segment on the 856 to Cancel BOs for specific LUM/JIT accounts.  This required coordination with the vendor (Medline) to send only on the accounts we requested (not our Bulk Accounts)

See Infor KB 1471128 “EDI Using YNQ Segment to set Cancel Backorder in MA531CSV”   

The benefit of this method as compared to using the PO10.1 or PO10.2 Cancel Back Order is that the YNQ is line specific.

Kat V, Why have you always left Cancel Remaining up to the buyer? What are the drawbacks of automating?

We're a JIT organization and the departments will be given the choice to wait for the product or cancel and look for a sub. I don't think we've really looked at it since go live in 1998. I'm going to ask our new Admin Director if it's something to look at. We only accept the 856 from Cardinal, so I'm not sure if it's going to make that big an impact on our PO223.
