Hello,
I am trying to update a line in the Purchase Order (view PURCHASE_ORDER_LINE_PART). I want to update a price for several lines at the same time. Every time when I am trying to do that I have the following error message:

Entering a new line works perfectly, but the update of existing line doesn’t work. Has anybody encountered the following problem? Is it possible to update the Purchase Line with the Excel Add-In?
Thank you in advance,
