• What is the cause and solution for SAP error message /SAPAPO/OM031 - Mode linkage 'identity' has been violated ?

  The SAP error message /SAPAPO/OM031 indicates that there is a violation of the mode linkage 'identity' in the Advanced Planning and Optimization (APO) module. This error typically arises in the context of planning scenarios where certain constraints or relationships between different modes of operation are not being met.
  Cause:
  The error is usually caused by one of the following issues:
  
  
  Inconsistent Mode Linkage: The mode linkage defined in the system does not match the expected configuration. For example, if a certain mode is expected to be linked to another mode in a specific way (identity), but the actual configuration does not reflect this, the error will occur.
  
  
  Incorrect Master Data: There may be inconsistencies in the master data related to the product, resource, or planning object. This can include incorrect settings for production modes, resources, or planning strategies.
  
  
  Planning Object Configuration: The configuration of the planning object (like a product or resource) may not be set up correctly to support the required mode linkage.
  
  
  Solution:
  To resolve the error, you can take the following steps:
  
  
  Check Mode Linkage Configuration:
  
  Go to the configuration settings for mode linkages in the APO system.
  Verify that the mode linkage for the relevant planning object is set up correctly and matches the expected identity linkage.
  
  
  
  Review Master Data:
  
  Check the master data for the product or resource involved in the planning process.
  Ensure that all relevant settings (like production modes, resources, and planning strategies) are correctly defined and consistent.
  
  
  
  Adjust Planning Object Settings:
  
  If necessary, adjust the settings for the planning object to ensure that they align with the required mode linkage.
  This may involve changing the mode definitions or reassigning modes to the appropriate resources.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or notes related to mode linkages and the specific error message for additional guidance and best practices.
  
  
  
  Testing:
  
  After making changes, run a test planning run to ensure that the error no longer occurs and that the planning results are as expected.
  
  
  
  Related Information:
  
  Transaction Codes: You may need to use transaction codes like /SAPAPO/OM01 (for mode linkage maintenance) or /SAPAPO/MC90 (for checking planning object settings) to access the relevant configuration areas.
  SAP Notes: Check for any SAP Notes that may address this specific error or provide additional troubleshooting steps.
  Support: If the issue persists after following the above steps, consider reaching out to SAP support for further assistance, providing them with detailed information about the error and the steps you have already taken.
  
  By following these steps, you should be able to identify and resolve the cause of the /SAPAPO/OM031 error in your SAP APO system.
