Hi Mac, Thanks for your response. I have setup in system parameter for " Allow Issue of Non Allocated Components to Shop Orders = *NO ' ( does 405 CD have this system parameter too ? ) But when user did inventory transaction type I ( single issue ) for WH which isn't same with FMA/MWHS, program gives error message " Item number, warehouse, or sequence number incorrect for this shop order. " This error message urges user to do Shop Order allocation. User asked me " Why he must allocate for items have no allocation required at facility planning data." Do you ever facing experience for this issue ..? Thanks.
