• What is the cause and solution for SAP error message RS_DB_DB6544 - Distribution key for E fact table &1 differs from metadata ?

  The SAP error message RS_DB_DB6544 indicates that there is a mismatch between the distribution key defined in the metadata and the actual distribution key used in the fact table (E fact table) in the database. This can occur in SAP BW (Business Warehouse) environments, particularly when dealing with data modeling and data loading processes.
  Cause:
  
  Metadata Changes: The distribution key in the metadata may have been changed after the fact table was created or populated, leading to inconsistencies.
  Data Load Issues: If data was loaded into the fact table without adhering to the defined distribution key, it can cause this error.
  Manual Changes: Manual changes to the database or the underlying structures without updating the metadata can lead to discrepancies.
  Transport Issues: If the transport of changes between systems (e.g., from development to production) was not executed properly, it could lead to mismatches.
  
  Solution:
  
  Check Metadata: Verify the distribution key defined in the metadata for the E fact table. Ensure it matches the actual structure of the fact table in the database.
  Recreate the Table: If the distribution key has changed, you may need to recreate the fact table to align it with the updated metadata. This can be done through the Data Warehousing Workbench.
  Data Load: If the issue arose during a data load, check the data load process and ensure that it adheres to the defined distribution key. You may need to reload the data after correcting the issue.
  Repair Metadata: If the metadata is incorrect, you can repair it using the appropriate transaction codes (like RSA1) to adjust the distribution key settings.
  Check for Transport Errors: If the issue is related to transport, ensure that all relevant objects were transported correctly and that there are no missing components.
  
  Related Information:
  
  Transaction Codes: Use transaction codes like RSA1 (Data Warehousing Workbench) to check and manage InfoObjects, InfoProviders, and data loads.
  SAP Notes: Check SAP Notes for any known issues or patches related to this error message. SAP frequently updates its knowledge base with solutions for common problems.
  Documentation: Refer to SAP BW documentation for best practices on managing metadata and data loading processes.
  Support: If the issue persists, consider reaching out to SAP support for assistance, especially if it involves complex data models or custom developments.
  
  By following these steps, you should be able to resolve the RS_DB_DB6544 error and ensure that your fact table's distribution key is consistent with the metadata.
