The SAP error message IW856 indicates that the order type specified (represented by &1) is restricted to refurbishment processes. This means that the order type you are trying to use is not applicable for the operation you are attempting to perform, such as creating or processing a maintenance order, production order, or any other type of order that is not related to refurbishment.
Cause: Incorrect Order Type: The order type you are using is specifically configured for refurbishment activities, and you are trying to use it for a different purpose. Configuration Settings: The order type may have been set up in the system to only allow refurbishment-related activities, which restricts its use for other types of orders. User Error: The user may have selected the wrong order type inadvertently.
Solution: Check Order Type: Verify that you are using the correct order type for the intended operation. If you are not performing refurbishment, select an appropriate order
