As Simon said on a previous thread! Quote: This is probably a discussion for another thread but we seemed to find that a lot of things worked fine with some tweaking until Warehouse Management was turned on. We can use this thread to let other know about NAD problems encountered and how we tweaked them! We had a few problems with Variants as the project we are working on has mandatory variants, but if you put a Variant code in the BOM, when you explode the BOM no Variant is assigned. Not specificly NAD but a starting point! David Cox MindSource (UK) Limited Navision Solutions Partner Email: david@mindsource.co.uk Web: www.mindsource.co.uk
