• What is the cause and solution for SAP error message /SAPAPO/RBA406 - Do not use INC MD prod. subst. proc. with INC MD loc. prod substitns ?

  The SAP error message /SAPAPO/RBA406 indicates a conflict in the configuration of substitution processes in the Advanced Planning and Optimization (APO) module, specifically related to the use of "Incremental" (INC) methods for both product substitution and location product substitution.
  Cause:
  The error occurs when there is an attempt to use incremental methods for both product substitution and location product substitution simultaneously. In SAP APO, these two types of substitution processes are not designed to work together in an incremental manner. The system is essentially indicating that the configuration is inconsistent or not allowed.
  Solution:
  To resolve this error, you need to adjust the configuration settings for the substitution processes. Here are the steps you can take:
  
  
  Review Configuration: Check the settings for product substitution and location product substitution in the APO system. Ensure that you are not using both as incremental methods at the same time.
  
  
  Change Substitution Method:
  
  If you need to use incremental methods, decide which substitution process (product or location) should be set to incremental and change the other to a non-incremental method.
  Alternatively, if both need to be used, consider switching both to a non-incremental method.
  
  
  
  Test Changes: After making the necessary adjustments, test the configuration to ensure that the error no longer occurs and that the substitution processes work as intended.
  
  
  Consult Documentation: Refer to SAP documentation or help guides for detailed information on configuring product and location product substitutions. This can provide insights into best practices and potential limitations.
  
  
  Seek Support: If you are unable to resolve the issue, consider reaching out to SAP support or consulting with an SAP expert who specializes in APO for further assistance.
  
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that might address this specific error or provide additional guidance on configuration.
  APO Documentation: Review the official SAP APO documentation for detailed explanations of product substitution and location product substitution processes.
  Community Forums: Engage with SAP community forums or user groups where similar issues may have been discussed, and solutions shared.
  
  By following these steps, you should be able to resolve the error and ensure that your substitution processes are configured correctly in SAP APO.
