• What is the cause and solution for SAP error message VMP_MSG079 - Simulation parameters do not match the parameters defined in the PSA date ?

  The SAP error message VMP_MSG079 indicates that there is a mismatch between the simulation parameters you are trying to use and the parameters that are defined in the PSA (Persistent Staging Area) data. This error typically occurs in the context of SAP BW (Business Warehouse) or SAP BW/4HANA when working with data extraction and transformation processes.
  Cause:
  The error can be caused by several factors, including:
  
  
  Parameter Mismatch: The parameters you are using for the simulation (e.g., selection criteria, filters, or other settings) do not match the parameters that were originally defined when the data was loaded into the PSA.
  
  
  Changes in Data Model: If there have been changes to the data model, such as changes in the InfoObject definitions, data types, or attributes, this can lead to discrepancies.
  
  
  Data Source Configuration: If the data source configuration has been altered after the data was loaded into the PSA, it may lead to inconsistencies.
  
  
  Versioning Issues: If you are working with different versions of the data or if the data has been updated, this can also lead to parameter mismatches.
  
  
  Solution:
  To resolve the error, you can take the following steps:
  
  
  Check Simulation Parameters: Review the parameters you are using for the simulation and ensure they match the parameters defined in the PSA. This includes checking filters, selection criteria, and any other relevant settings.
  
  
  Review PSA Data: Look at the data in the PSA to understand what parameters were used during the data load. You can do this by accessing the PSA table and examining the relevant fields.
  
  
  Update Data Source: If there have been changes to the data source or data model, ensure that the data source is updated and that the PSA is refreshed accordingly.
  
  
  Reprocess Data: If necessary, you may need to reprocess the data in the PSA to align it with the current parameters. This may involve reloading the data from the source system.
  
  
  Consult Documentation: Check SAP documentation or notes related to the specific version of SAP BW you are using for any known issues or additional troubleshooting steps.
  
  
  Contact Support: If the issue persists after trying the above steps, consider reaching out to SAP support for further assistance.
  
  
  Related Information:
  
  SAP BW Documentation: Review the official SAP BW documentation for detailed information on PSA and data extraction processes.
  SAP Notes: Search for relevant SAP Notes that may address this specific error message or provide additional troubleshooting steps.
  Community Forums: Engage with SAP community forums or user groups where similar issues may have been discussed.
  
  By following these steps, you should be able to identify and resolve the cause of the VMP_MSG079 error in your SAP environment.
