In trade agreement I am setting Sales Price for the Item group and Customer Group.
I can select customer group as whole-seller but when I select “Group” in Item code field and then select a product group in item relation field then system shows an error “Illegal combination of relation and item code”.
I’m having the same problem. I have a whole set of items that have the same price, so pricing them on group level rather than on individual item level would save time. I think however that the option to set the price on a group of items is not supported in AX. Unless you have found the answer in the mean time?
