I'm looking at Sender ID which maps to bkedi.dun.duns according to the edimap.txt file.  This same value ends up in the SO record as the customer code.  I don't see that documented anywhere. How do you handle customers with multiple ship to locations?  I see that there is a mapping for bill code and ship code but they go into the extra field.  Many of our contract prices are based on ship to and fall back to bill to.  Do we just have to manually edit the edi info every time?  
 
Even where there are contract prices for a bill to code which is correctly imported from sender id we still have to tab through each line item on the order to get the contract price to show up.   The price field is initially populated with the base price.
 
We will probably end up not importing price from  edi messages (or just translate it to 0) and just tab through each line item if that's what it takes.
