Allow Line Discount

A customer gets a good rate of invoice discount and so we want to block any line discount. However, unticking the “Allow Line Discount” box on the customer card doesn’t seem to work - possibly because it’s been overridden by “Allow Line Discount” against the item (or, maybe, against the Customer Price Group?)?

Has anyone else had this problem, and does anyone know of a solution?

Thanks.

The field “Allow Line Disc.” Isn’t used to block manually inserted line discounts. That field it’s used when calculating best price to display in sales invoice. If you want to always block discount you could remove field from form. Other solutions you probably have to follow custom coding way.

Thanks!
