• What is the cause and solution for SAP error message RS_PSA_DEP078 - Duplicate records in RSTSODS for table &1 ?

  The SAP error message RS_PSA_DEP078 indicates that there are duplicate records in the RSTSODS table for a specific DataSource. This typically occurs during the extraction or loading process when the system detects that the same record is being inserted multiple times into the PSA (Persistent Staging Area) for a given DataSource.
  Cause:
  
  Duplicate Data in Source System: The source system may have duplicate records that are being extracted.
  Incorrect Data Transfer Process: The data transfer process may not be correctly configured, leading to the same records being extracted multiple times.
  Issues with Delta Mechanism: If you are using delta loads, there may be issues with the delta mechanism that cause the same records to be loaded repeatedly.
  Manual Data Manipulation: If there has been manual intervention or data manipulation in the PSA, it could lead to duplicates.
  
  Solution:
  
  Check Source Data: Verify the source data for duplicates. If duplicates exist, you may need to clean the data in the source system.
  Review Data Transfer Process: Ensure that the data transfer process is correctly configured. Check the extraction logic and ensure that it is not set to extract the same records multiple times.
  Delta Load Configuration: If you are using delta loads, check the delta configuration. Ensure that the delta mechanism is functioning correctly and that it is not causing duplicates.
  Delete Duplicates in PSA: You can manually delete the duplicate records from the PSA table. Use transaction code RSA1 to access the Data Warehousing Workbench, navigate to the PSA, and delete the duplicates.
  Use Data Cleansing Tools: Consider using data cleansing tools or processes to identify and remove duplicates before they reach the PSA.
  Check for Custom Logic: If there is any custom logic implemented in the extraction process, review it to ensure it is not causing duplicates.
