This error indicates that there is a discrepancy in the data being loaded into a difference table, which is used for delta management in data extraction processes.
  Cause:
  The error message RSDS051 can occur due to several reasons, including:
  
  Data Mismatch: The data being extracted from the source system does not match the expected format or values in the BW system.
