• What is the cause and solution for SAP error message RS_PSA_DEL018 - No source system available for this pattern ?

  The SAP error message RS_PSA_DEL018 indicates that there is no source system available for the specified data transfer pattern in the context of the SAP BW (Business Warehouse) system. This error typically occurs when trying to delete or manage data in the Persistent Staging Area (PSA) and the system cannot find the corresponding source system for the data.
  Cause:
  
  Missing Source System: The source system that was originally used to load the data into the PSA is no longer available or has been deleted.
  Incorrect Configuration: The data transfer process (DTP) or the InfoPackage may be incorrectly configured, leading to a mismatch in the source system.
  Transport Issues: If the source system was transported to another environment (e.g., from development to production), it may not have been set up correctly in the new environment.
  Data Source Deactivation: The data source associated with the PSA might be deactivated or not properly configured.
  
  Solution:
  
  
  Check Source System Configuration:
  
  Go to the SAP BW system and check the configuration of the source system in the RSA1 transaction (Data Warehousing Workbench).
  Ensure that the source system is active and properly configured.
  
  
  
  Review Data Transfer Process (DTP):
  
  Check the DTP associated with the PSA. Ensure that it points to the correct source system and that the settings are correct.
  If necessary, recreate the DTP to ensure it is correctly linked to the source system.
  
  
  
  Check InfoPackage:
  
  Review the InfoPackage that was used to load the data into the PSA. Ensure that it is correctly configured and that the source system is still valid.
  
  
  
  Recreate the Source System:
  
  If the source system has been deleted or is missing, you may need to recreate it in the BW system.
  
  
  
  Check for Transport Issues:
  
  If the issue arose after a transport, verify that all necessary objects related to the source system were transported correctly.
  
  
  
  Consult SAP Notes:
  
  Check the SAP Support Portal for any relevant SAP Notes that may address this specific error or provide additional troubleshooting steps.
