• What is the cause and solution for SAP error message RSLPO_DFG138 - 'Use Aggregates' is inconsistent (actual='&1', target='&2') ?

  The SAP error message RSLPO_DFG138, which states "'Use Aggregates' is inconsistent (actual='&1', target='&2')", typically occurs in the context of SAP BW (Business Warehouse) or SAP HANA when there is a mismatch between the data being processed and the expected data structure, particularly when dealing with aggregates.
  Cause:
  
  Inconsistent Data: The error usually indicates that there is a discrepancy between the actual data being processed and the expected target structure. This can happen if the data model has been changed (e.g., changes in InfoObjects, InfoCubes, or Aggregates) without properly updating the aggregates.
  Missing Aggregates: If the system expects to use aggregates for performance optimization but cannot find the appropriate aggregates, this error may occur.
  Data Load Issues: If there are issues during data loading processes (e.g., data is not loaded correctly into the aggregates), it can lead to inconsistencies.
  Incorrect Settings: The settings for the InfoProvider or the query may not be correctly configured to utilize aggregates.
  
  Solution:
  
  Check Aggregates: Verify that the aggregates are correctly defined and activated in the InfoCube. You can do this by navigating to the InfoCube in the Data Warehousing Workbench and checking the aggregates.
  Rebuild Aggregates: If the aggregates are inconsistent, consider rebuilding them. This can be done by going to the InfoCube and selecting the option to rebuild aggregates.
  Data Consistency Check: Perform a consistency check on the InfoCube and aggregates to ensure that all data is correctly aligned and that there are no missing or corrupt entries.
  Update Queries: If you are using queries that reference aggregates, ensure that they are correctly configured to use the appropriate aggregates. You may need to adjust the query settings.
  Data Load Monitoring: Monitor the data load processes to ensure that data is being loaded correctly into the aggregates. Check for any errors or warnings during the data load.
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional guidance on resolving it.
  
  Related Information:
  
  Transaction Codes: You can use transaction codes like RSA1 (Data Warehousing Workbench) to manage InfoProviders and aggregates.
  Performance Tuning: Understanding how aggregates work in SAP BW can help in optimizing performance and avoiding such errors in the future.
  Documentation: Refer to SAP Help documentation for detailed information on aggregates and their configuration.
  
  If the issue persists after trying the above solutions, it may be beneficial to consult with your SAP Basis or BW team for further analysis and troubleshooting.
