A bit of help with solution design. Has anyone attempted to insert approvals into the inventory adjustment process? Am I correct in thinking that the only way to accomplish this is with approvals on a custom transaction?

@reptar As far as I remember this can be accomplish by a native NetSuite module: Inventory Count(SCM (Supply Chain Management) -> Inventory Management -> Basic Inventory Management -> Inventory Count). That module or within that module there is a concept of cycle counts or inventory count, the person who counts can't immediately adjust, upon approval of that count record then an inventory adjustment would or could be generated.
