thanks both, @AK47, that's what we have been using but problem is with direct posting for the assembly item, as soon as the assembly item has direct posting ticked, based the BOM revision associated with the BOM, if we have an order than has both an inventory item and assembly item, with the other charge or service for purchase, we would run into the cannot have direct and non direct revenue posting and it would error hence because you cannot ticked the revenue recognition for other charge or service for purchase, tried to change to other charge for resale item as that solves the direct/indirect but subsequently these don't appear on the PO for outsourcing manufacturing?
