• What is the cause and solution for SAP error message RSAR391 - Export DataSource not possible for generated ODS-PSAs ?

  The SAP error message RSAR391 indicates that there is an issue with exporting a DataSource for generated ODS (Operational Data Store) PSAs (Persistent Staging Area). This error typically arises in the context of SAP BW (Business Warehouse) when trying to extract data from a source system into a DataSource that is linked to an ODS object.
  Cause of the Error
  The error can occur due to several reasons, including:
  
  
  DataSource Configuration Issues: The DataSource may not be properly configured or activated. If the DataSource is not set up correctly, it cannot be exported.
  
  
  ODS Object Status: The ODS object may not be in a state that allows data extraction. For example, if the ODS object is not activated or is in a "not active" state, it can lead to this error.
  
  
  Technical Settings: There may be issues with the technical settings of the DataSource or the ODS object, such as incorrect field mappings or data types.
  
  
  Transport Issues: If the DataSource or ODS object was recently transported from another system, there may be inconsistencies or missing components.
  
  
  Version Compatibility: There may be compatibility issues between the version of the DataSource and the ODS object.
  
  
  Solution
  To resolve the RSAR391 error, you can follow these steps:
  
  
  Check DataSource Activation:
  
  Go to the DataSource in the SAP BW system and ensure that it is activated. You can do this in the Data Warehousing Workbench (transaction RSA1).
  
  
  
  Verify ODS Object Status:
  
  Check the status of the ODS object. Ensure that it is activated and ready for data extraction. You can check this in the ODS object maintenance screen.
  
  
  
  Review Technical Settings:
  
  Review the technical settings of both the DataSource and the ODS object. Ensure that the field mappings are correct and that the data types match.
  
  
  
  Re-transport if Necessary:
  
  If the DataSource or ODS object was recently transported, consider re-transporting it or checking for any missing components.
  
  
  
  Check for Updates:
  
  Ensure that your SAP BW system is up to date with the latest patches and updates, as there may be bug fixes related to this issue.
  
  
  
  Consult SAP Notes:
  
  Look for relevant SAP Notes in the SAP Support Portal that may address this specific error. SAP Notes often provide detailed solutions or workarounds.
  
  
  
  Debugging:
  
  If the issue persists, consider debugging the extraction process to identify the exact point of failure.
