• What is the cause and solution for SAP error message RM874 - Routing header changed (UoM). Not possible to set up rep. points again ?

  The SAP error message RM874 ("Routing header changed (UoM). Not possible to set up rep. points again") typically occurs in the context of production planning and routing in SAP. This error indicates that there has been a change in the routing header, specifically related to the unit of measure (UoM), which affects the ability to set up representative points for the routing.
  Cause:
  
  Change in Unit of Measure: The most common cause of this error is that the unit of measure for the routing has been changed after the routing was initially created. This can happen if the UoM is modified in the material master or routing master data.
  Inconsistent Data: If there are inconsistencies in the data related to the routing, such as changes in the components or operations that are not aligned with the new UoM, this can trigger the error.
  Routing Changes: Any changes made to the routing header, such as modifications to the operations, components, or sequences, can also lead to this error if they are not compatible with the existing setup.
  
  Solution:
  
  Check Routing Header: Review the routing header to identify any changes made to the unit of measure. Ensure that the UoM is consistent with the material master and other related data.
  Recreate Representative Points: If the UoM has changed, you may need to recreate the representative points for the routing. This can be done by deleting the existing representative points and setting them up again based on the new UoM.
  Consistency Check: Perform a consistency check on the routing and related master data to ensure that all components, operations, and sequences are aligned with the current UoM.
  Consult Documentation: Refer to SAP documentation or help resources for specific steps on how to handle routing changes and representative points.
  Transport Changes: If the changes were made in a development environment, ensure that they are properly transported to the production environment without inconsistencies.
  
  Related Information:
  
  Transaction Codes: You may use transaction codes like CA01 (Create Routing), CA02 (Change Routing), and CA03 (Display Routing) to manage routing data.
  Unit of Measure Configuration: Check the configuration settings for units of measure in the material master and ensure they are set up correctly.
  SAP Notes: Look for relevant SAP Notes that may address this specific error or provide additional troubleshooting steps.
  User Exits and BAdIs: If custom logic is involved in routing or UoM handling, check for any user exits or BAdIs that might be affecting the behavior.
  
  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 routing.
