• What is the cause and solution for SAP error message CP287 - Hdr unit & of ref.op.set and referenced op.set do not match. ?

  The SAP error message CP287 indicates a mismatch between the header unit of the reference operation set and the referenced operation set in a production order or a similar context. This error typically arises in the context of production planning and control, particularly when dealing with routing and operation sets.
  Cause:
  
  Mismatch in Units: The header unit of measure (UoM) for the operation set does not match the unit of measure for the referenced operation set. This can happen if the operation sets are defined with different units or if there is an inconsistency in the configuration.
  Configuration Issues: There may be issues in the configuration of the routing or the production order that lead to this mismatch.
  Data Entry Errors: Incorrect data entry when creating or modifying the production order or operation set can lead to this error.
  Changes in Master Data: If there have been changes in the master data (like material master, routing, etc.) that affect the units of measure, it can lead to this error.
  
  Solution:
  
  Check Operation Sets: Review the operation sets involved in the production order. Ensure that the header unit of measure matches the unit of measure of the referenced operation set.
  Review Routing: Check the routing associated with the production order. Ensure that all operations and their units of measure are consistent.
  Correct Data Entry: If the error is due to incorrect data entry, correct the entries in the production order or operation set.
  Update Master Data: If there have been changes in the master data, ensure that all related data is updated consistently across the system.
  Consult Documentation: Refer to SAP documentation or help resources for specific guidance on the configuration of operation sets and routing.
  Testing: After making changes, test the production order or operation set to ensure that the error is resolved.
  
  Related Information:
  
  Transaction Codes: You may need to use transaction codes like CO02 (Change Production Order), CA01 (Create Routing), or CA02 (Change Routing) to review and modify the relevant data.
  Unit of Measure Configuration: Check the configuration of units of measure in the system to 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 implemented in your SAP system, check for any user exits or BAdIs that might affect the operation sets.
  
  By following these steps, you should be able to identify and resolve the cause of the CP287 error in SAP.
