• What is the cause and solution for SAP error message RSRV752 - Total number of duplicates in the PSA table: &1 ?

  The SAP error message RSRV752 indicates that there are duplicate records in the Persistent Staging Area (PSA) table for a specific DataSource. This can occur during data extraction processes when the same data is loaded multiple times without proper handling of duplicates.
  Cause:
  The primary cause of this error is the presence of duplicate records in the PSA table. This can happen due to various reasons, such as:
  
  Multiple data loads from the same source without proper data cleansing.
  Incorrect configuration of the DataSource or extraction process.
  Issues with the data source itself, leading to repeated records being extracted.
  
  Solution:
  To resolve the RSRV752 error, you can follow these steps:
  
  
  Identify Duplicates:
  
  Use transaction code RSRV to analyze the PSA table. You can check the number of duplicates and the specific records causing the issue.
  Execute the "Check" function in RSRV for the relevant DataSource to identify duplicates.
  
  
  
  Remove Duplicates:
  
  You can manually delete the duplicate records from the PSA table using transaction RSA1 (Data Warehousing Workbench) or directly in the database if you have the necessary permissions.
  Alternatively, you can use the "Delete" function in RSRV to remove duplicates automatically.
  
  
  
  Adjust Data Load Process:
  
  Review the data extraction process to ensure that it is configured correctly to avoid loading duplicates in the future.
  Implement checks or filters in the data extraction logic to prevent duplicates from being loaded into the PSA.
  
  
  
  Data Cleansing:
  
  If duplicates are a recurring issue, consider implementing data cleansing processes at the source or during the ETL (Extract, Transform, Load) process to ensure that only unique records are loaded into the PSA.
  
  
  
  Monitoring:
  
  Set up monitoring and alerts for data loads to catch duplicate issues early in the process.
