Do I have to mark my list as a ‘Sales’ price list? What does that do?

Yes, this is a critical step. The “Sales” checkbox tells the system that this list contains temporary, promotional prices, not the channel’s standard price. If the “Sales” marker is missing, the system may not recognize the price list as a valid sales price list, which leads to complications during export.

Solution:

•Go to “Articles > Price catalogue”

•Select your price list.

•Select the “Sales” checkbox.

•Save your settings.
