Good morning.
I have made a query on Purchase Lines table in Query Designer in NAV 2018
I want to set a filter, only those lines where Item No is not empty, and I am following the instructions here
https://learn.microsoft.com/en-us/dynamics-nav/how-to--set-up-filter-rows-in-query-designer
I added the filter row, however I hit a snag when I tried to set up the filter, the name is not unique.
What can I do to overcome this?



Many thanks
Louise
