RE: Changing the Posting Group for a group of inventory items? Can several be done at once?
Hi Rebekah,
that's a little dangerous. Moving the items to a new posting group won't affect existing purchase/sales/service order/WMS (incoming, outgoing, transfer)/item journal lines. By this I mean the tables, affecting all types of unposted documents. All these will be posted with the old group code unless your change routine also is changing these, too.
Also, the command you're referring to is C/AL. You can use it in a batch (report or codeunit), and it will do what you require. To use it, though, you need access to the development environment, an apropriate NAV license, and the know-how for writing such a batch. Your NAV partner should be able to do it easily.
The correction of the costing would probably work as you intended.
with best regards
Jens
