• What is the cause and solution for SAP error message MH230 - Sales unit not changeable since material used as production resource/tool ?

  The SAP error message MH230 indicates that the sales unit of a material cannot be changed because the material is being used as a production resource/tool (PRT). This typically occurs in the context of production planning and control, where certain materials are designated as PRTs and are linked to production orders or other processes.
  Cause:
  
  Material Status: The material is currently assigned as a production resource/tool in one or more production orders or routings.
  Dependencies: Changing the sales unit may affect the production processes that rely on the material, leading to inconsistencies in inventory management and production planning.
  Configuration: The material may have specific configurations or settings that prevent changes to its sales unit when it is being used in production.
  
  Solution:
  
  Check Usage: Review the production orders, routings, or any other processes where the material is being used as a PRT. You can do this by navigating to the relevant production order or routing in SAP.
  Remove from Production: If possible, remove the material from any active production orders or routings. This may involve:
  
  Deleting or changing the production order.
  Unassigning the material from the routing.
  
  
  Change Sales Unit: Once the material is no longer being used as a PRT, you should be able to change the sales unit without encountering the error.
  Reassign if Necessary: If you need to continue using the material as a PRT after changing the sales unit, you may need to reassign it in the production orders or routings after the change.
  
  Related Information:
  
  Transaction Codes: You may use transaction codes like CO02 (Change Production Order), CS02 (Change Material BOM), or CR02 (Change Routing) to manage production orders and routings.
  Material Master: Check the material master data using transaction code MM02 to see the settings related to the sales unit and PRT status.
  Documentation: Refer to SAP documentation or help files for more detailed information on managing production resources and tools, as well as handling material master data.
  
  Best Practices:
  
  Always ensure that changes to material master data are carefully planned and executed, especially when materials are actively used in production.
  Maintain clear documentation of any changes made to production orders or material settings to avoid confusion in the future.
  Regularly review and clean up unused production resources/tools to prevent similar issues from arising.
  
  If the issue persists after following these steps, it may be beneficial to consult with your SAP support team or a functional consultant who specializes in production planning and control.
