I have created a Fixed Assets item. I created a PO there is a Type column I clicked Fixed Assets and No. I clicked FA00210, but there is a message said "Gen Prod Posting Group must have a value in G/L Acct. No. =13106. It cannot be zero or empty.
in standart Navision these two have nothing to do with posting group info (although I havre seen modifications, where a link to default PGs was added to Classes/Subclasses for ease of FA entry, OR, maybe some localisations have that included)
PGs are set in lower (“grid”) part of FA card, where you add line(s) Depreciation Book(s) for the FA.
However, Bhing is correct saying that FA PG itself must be set up in
you must fill in there all appropriate G/L accounts, as with any PG setup.
