We are planning for a pending price increase from a supplier. The updated prices have been recorded for each item in the IC Vendor Details. However when one of these items is received against an older PO at the earlier cost the Vendor Details value is automatically changed back to the pre-increase price.

I have checked all the service pack readme files and don't find any mention of this as a known issue. How do we process receipts against old cost PO's while issuing new PO's at our post increase values without having to manually review each and every transaction?

Vendor Details are updated when you run IC day end processing, that's the way the program is designed. Instead look at Vendor Contract Costs under PO Setup.

 Thanks Etienne. I will check it out Contract Pricing.
