• What is the cause and solution for SAP error message MPE_INSTALLATION_MSG026 - Reference point in BOM and routing differs ?

  The SAP error message MPE_INSTALLATION_MSG026 indicates that there is a discrepancy between the reference point defined in the Bill of Materials (BOM) and the routing for a particular material. This error typically arises during the production planning or execution processes when the system detects that the reference points do not match, which can lead to issues in production scheduling and material requirements.
  Cause:
  
  Mismatch in Reference Points: The reference point in the BOM (which indicates where the components are to be used in the production process) does not align with the reference point in the routing (which defines the sequence of operations and the work centers involved).
  Changes in BOM or Routing: If there have been recent changes to either the BOM or the routing, and these changes were not synchronized, it can lead to this error.
  Incorrect Configuration: The configuration settings for the BOM or routing may not be set up correctly, leading to inconsistencies.
  
  Solution:
  
  
  Check BOM and Routing: 
  
  Review the BOM and routing for the material in question. Ensure that the reference points are consistent across both documents.
  You can use transaction codes like CS03 (Display BOM) and CA03 (Display Routing) to check the details.
  
  
  
  Synchronize Changes: 
  
  If changes were made to either the BOM or routing, ensure that they are updated and synchronized. This may involve updating the reference points to match or adjusting the BOM/routing as necessary.
  
  
  
  Adjust Reference Points: 
  
  If the reference points are indeed different and should be, you may need to adjust one of them to ensure they align. This could involve changing the BOM or routing to reflect the correct reference point.
  
  
  
  Consult Documentation: 
  
  Review any relevant documentation or guidelines for your specific SAP implementation to ensure that you are following the correct procedures for managing BOMs and routings.
  
  
  
  Testing: 
  
  After making adjustments, perform a test run to ensure that the error does not reoccur and that production can proceed without issues.
  
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as CS01 (Create BOM), CS02 (Change BOM), CA01 (Create Routing), and CA02 (Change Routing) for managing BOMs and routings.
  SAP Notes: Check SAP Notes for any known issues or patches related to this error message. SAP frequently updates its knowledge base with solutions for common problems.
  User Roles: Ensure that users have the appropriate roles and permissions to make changes to BOMs and routings, as insufficient permissions can also lead to errors.
  
  By following these steps, you should be able to resolve the MPE_INSTALLATION_MSG026 error and ensure that your BOM and routing are correctly aligned for production processes.
