Before the last update - in the INV_HIST_LINE grid, the Customer column worked (Field name defined as ISFUNC.CUSTNME() showed customer name when the shipment button is clicked ) - it no longer works.

Worked - thanks.  

Step 1 get the latest wbklookup.rwn from Lynn.
 
 
Step 2 edit the PO_HST_LINE grid in SU-A and change the ISFUNC.VENDNME() to ISFUNC.VENDNME2()
 

OK - I sort of understand that, but if it only shows open PO's, it sort of defeats the purpose of hitting the receipts button (for us anyway) - which is to get a quick (single click) history of who we bought stuff from for a specific item number.
 
Do I still want to use Allen's suggested actions of an updated wbklookup or not?

That is correct, the VENDNME2 function that is correctly looking at the receipts file is defined in the updated lookup file but no the older one.

Never mind - didn't see the later e-mail.
