We need to be able to posts costs to a part specific (or partgroup/class) G/L account but the system seems to fixed to only use the default set against the company in the inventory costs WIP G/L Set.
Has anyone got any ideas on how to do this?
You have not provided much information, so it is difficult to say. You should be able to direct the adjustments to whatever account you want with the GL Control Codes.
For the Part Class.
