Great post! But be aware (don't read as Awara:) of using RUB currency card. If user will pickup it in any document (f.ex.) sales order, NAV will "think" that this is currency document, and will try to create currency adjustments on apply. Also in many places in posting CU there is check : IF "Currency code " <>''... So there should be another solution, or this RUB should be blocked from using in documents
