• What is the cause and solution for SAP error message V1816 - Assembly process only possible for engineer or cust. make-to-order prod. ?

  The SAP error message V1816 indicates that the assembly process is only possible for engineer-to-order (ETO) or customer make-to-order (MTO) products. This error typically arises when you attempt to perform an assembly process on a product that is not configured to be produced in this manner.
  
  Cause:
  
  Product Configuration: The product you are trying to assemble is not set up as an engineer-to-order or make-to-order item in the system. This means that the item is likely configured as a stock item or a make-to-stock item, which does not support the assembly process in the same way.
  Order Type: The order type you are using may not be compatible with the assembly process. For example, standard production orders may not allow for assembly processes that are specific to ETO or MTO.
  Master Data Settings: The material master data or the bill of materials (BOM) may not be correctly configured to allow for assembly processing.
