Once you have a new Contract Price Group ready it is very easy to roll that our to the select Debtors codes.
This is all done inside the Debtors module:-
Pricing
Contract Prices
Select 'Global Pro'
Enter your criteria are required.
This example is updating Debtors from MaaSomething to MaaZZZZZZZZ, that are in the GEM buying group. The new Price list is in Contract Price Profile ‘ZGEM / G9’.
You may not need to restrict to a particular range of Debtor accounts of course, and do the entire Buying Group at the one time.
Clicking on ‘CHG Grp’ will update the selected Debtors to use the new Price List
