• What is the cause and solution for SAP error message RSRV753 - No Duplicates found in the PSA table ?

  The SAP error message RSRV753 "No Duplicates found in the PSA table" typically occurs in the context of data extraction and loading processes, particularly when working with the Persistent Staging Area (PSA) in SAP BW (Business Warehouse). This message indicates that the system did not find any duplicate records in the PSA table that match the criteria specified in the check.
  Cause:
  
  No Duplicates Present: The primary reason for this message is that there are indeed no duplicate records in the PSA table for the specified data source.
  Data Load Issues: If the data load process was not executed correctly or if the data was not loaded at all, the PSA table may not contain any records.
  Incorrect Selection Criteria: The criteria used to check for duplicates may not be correctly defined, leading to a situation where the system cannot find any duplicates even if they exist.
  Data Cleansing: If data cleansing processes have been applied, they may have removed duplicates before this check was performed.
  
  Solution:
  
  Verify Data Load: Check if the data load process was executed successfully. You can do this by reviewing the data load logs and ensuring that records were loaded into the PSA table.
  Check PSA Table: Use transaction codes like RSA1 or SE11 to directly inspect the PSA table for the relevant data source. This will help you confirm whether records exist and if duplicates are present.
  Review Selection Criteria: Ensure that the selection criteria used for the duplicate check are correct. If necessary, adjust the criteria to accurately reflect the conditions under which duplicates should be identified.
  Data Quality Checks: If you suspect that data cleansing processes may have removed duplicates, review those processes to ensure they are functioning as intended and not overly aggressive in removing records.
  Run Duplicate Check Again: After verifying the above points, you can run the duplicate check again to see if the issue persists.
  
  Related Information:
  
  PSA (Persistent Staging Area): The PSA is a temporary storage area in SAP BW where data is stored after extraction from the source system and before it is transformed and loaded into the data warehouse.
  Data Load Monitoring: Use transaction RSA1 to monitor data loads and check for any errors or warnings that may indicate issues with the data extraction process.
  Data Quality Management: Implement data quality management practices to ensure that data loaded into the PSA is accurate and free of duplicates, which can help prevent issues in reporting and analysis.
  
  If the problem persists after following these steps, it may be beneficial to consult with your SAP BW administrator or support team for further investigation.
