• What is the cause and solution for SAP error message WS794 - Personnel settlement header data are not unique; check input data. ?

  The SAP error message:
  WS794: Personnel settlement header data are not unique; check input data.
  
  Cause:
  This error occurs when the system detects multiple personnel settlement header records with the same key fields during a personnel settlement process (e.g., in payroll or personnel administration). Essentially, the system expects a unique header record for a given personnel settlement, but finds duplicates due to inconsistent or duplicate input data.
  Common reasons include:
  
  Duplicate entries in the personnel settlement header data.
  Incorrect or inconsistent key fields (such as personnel number, settlement period, or payroll area) causing multiple records to be interpreted as identical.
  Data inconsistencies due to manual data entry errors or incorrect data migration.
  Issues in infotype data (e.g., Infotype 2010 - Employee Remuneration Info) or payroll results that cause the system to generate multiple headers.
  
  
  Solution:
  
  
  Check Input Data:
  
  Verify the personnel number and settlement period entered.
  Ensure that the key fields used to identify the personnel settlement header are unique.
  Check for duplicate records in the relevant infotypes or payroll results.
  
  
  
  Use SAP Reports/Transactions:
  
  Use transaction PC_PAYRESULT or PC00_MXX_CALC (where XX is the country grouping) to check payroll results.
  Use PA20/PA30 to review personnel infotypes related to settlements.
  Use report RPCALCX0 or similar to analyze payroll results and settlement data.
  
  
  
  Data Cleanup:
  
  If duplicates are found, delete or correct the duplicate records.
  If the issue is due to incorrect infotype data, correct the infotype entries.
  If the problem is due to payroll results, consider re-running payroll or deleting incorrect payroll results using PC00_MXX_CLRT.
  
  
  
  Technical Analysis:
  
  Check the database tables related to personnel settlement headers (e.g., PCL2 or other relevant tables depending on the module).
  Debug or analyze the program/report generating the error to identify why duplicates are created.
