The field IWM.WMCOMP (Company Number) is only used in G/L functions. Concretely it is retrieved by the macro WMCOMP during the process INV920 and it is currently used as a segment. Therefore, until I know, that is the only standard BPCS implication. You must revise the CEA models setup in order to see if your change can or not affect your General Ledger. Francesc Junyent Barcelona Original message ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ All... What are the ramifications of changing the company number WMCOMP in the IWM file. We've recently done a product line / company consolidation and now one of the warehouses has primarily a different company's items in it. We base a custom report off that information, but I was wondering if there are BPCS implications if I changed the warehouse code. Thanks in advance for your advice!
