Following… I have a related problem trying to keep the QuoteDtl.Discount% and QuoteDtl.Discount £amount to remain when the QuoteDtl.SellingExpectedQty is changed, as they currently revert to 0.00 by design, which is driving our sales team nuts.
I have been able to get the % discount to stick thanks to help on the thread, but not the discount amount.
Haven’t tried Rest Api/ C# coding yet.
A uBaq was suggested.
