• What is the cause and solution for SAP error message R8654 - Field &1: key field (not dependent on extract structure) ?

  The SAP error message R8654 typically indicates an issue related to the extraction of data from a data source, particularly in the context of SAP BW (Business Warehouse) or SAP Data Warehousing. The message suggests that there is a problem with a key field that is not dependent on the extract structure, which can lead to issues during data extraction or transformation processes.
  Cause:
  
  Key Field Configuration: The key field in question may not be properly configured in the data source or the InfoObject. This can happen if the key field is not defined correctly in the underlying table or if it is not included in the extract structure.
  Data Source Issues: The data source may not be set up correctly, or there may be inconsistencies between the data source and the InfoProvider.
  Missing Dependencies: The key field may be expected to have certain dependencies that are not met, leading to the error.
  Data Model Changes: Changes in the data model, such as modifications to the InfoObject or the underlying database table, can also lead to this error.
  
  Solution:
  
  Check Key Field Configuration: Verify that the key field is correctly defined in the data source and that it is included in the extract structure. Ensure that it is marked as a key field in the InfoObject.
  Review Data Source Settings: Go to the data source settings in the SAP BW system and ensure that all necessary fields are included and correctly mapped.
  Update Extract Structure: If the key field is missing from the extract structure, you may need to update the extract structure to include it. This can be done in the DataSource maintenance transaction (e.g., RSA1).
  Check for Dependencies: Ensure that any dependencies required for the key field are properly set up. This may involve checking relationships with other InfoObjects or data sources.
  Re-activate DataSource: Sometimes, simply reactivating the DataSource can resolve issues related to metadata inconsistencies.
  Consult Documentation: Review SAP documentation or notes related to the specific version of SAP BW you are using for any known issues or additional troubleshooting steps.
