• What is the cause and solution for SAP error message RS_PSA_DEP084 - Unexpected attribute: EXTTABL = &1 ?

  The SAP error message RS_PSA_DEP084, which states "Unexpected attribute: EXTTABL = &1," typically occurs in the context of data extraction and loading processes, particularly when dealing with the Persistent Staging Area (PSA) in SAP BW (Business Warehouse). This error indicates that there is an unexpected attribute or field in the data that is being processed.
  Cause:
  
  
  Data Structure Mismatch: The error often arises when the structure of the data being loaded into the PSA does not match the expected structure defined in the InfoSource or DataSource. This can happen if there are changes in the source system or if the DataSource has been modified without corresponding updates in the BW system.
  
  
  Incorrect DataSource Configuration: If the DataSource is not correctly configured or if there are inconsistencies in the mapping of fields, this error can occur.
  
  
  Data Quality Issues: Sometimes, the data itself may contain unexpected values or formats that do not align with the defined attributes in the BW system.
  
  
  Solution:
  
  
  Check DataSource and InfoSource Configuration:
  
  Verify that the DataSource in the source system is correctly configured and that it matches the structure expected in the BW system.
  Ensure that all fields in the DataSource are correctly mapped to the corresponding fields in the InfoSource.
  
  
  
  Update DataSource:
  
  If there have been changes in the source system, you may need to replicate the DataSource in BW. This can be done by going to the DataSource in the BW system and using the "Replicate DataSource" option.
  
  
  
  Check for Changes in Source System:
  
  Investigate if there have been any changes in the source system that could affect the data structure. If changes have been made, you may need to adjust the DataSource in BW accordingly.
  
  
  
  Data Quality Checks:
  
  Perform data quality checks on the source data to ensure that it adheres to the expected formats and values. Cleanse the data if necessary.
  
  
  
  Re-activate the DataSource:
  
  Sometimes, simply re-activating the DataSource in the BW system can resolve the issue. This can be done in the Data Warehousing Workbench.
  
  
  
  Check for Notes and Patches:
  
  Look for any SAP Notes or patches that may address this specific error. SAP frequently releases updates that can resolve known issues.
