• What is the cause and solution for SAP error message WPI020 - Personnel numbers must be transferred to table PERNR_TAB ?

  Certainly! Here's detailed information about the SAP error message WPI020: "Personnel numbers must be transferred to table PERNR_TAB":
  
  Error Message
  WPI020: Personnel numbers must be transferred to table PERNR_TAB
  
  Cause
  This error occurs in SAP HR (Human Resources) or Payroll processing when the system expects personnel numbers (PERNR) to be passed or transferred into an internal table named PERNR_TAB, but this table is either empty or not properly filled.
  
  The program or function module processing the personnel data requires a list of personnel numbers to work on.
  If the table PERNR_TAB is empty or missing, the system cannot proceed because it does not know which personnel records to process.
  This often happens in custom reports, payroll schemas, or user exits where personnel numbers must be explicitly passed to the processing logic.
  It can also occur if the selection screen or data retrieval logic fails to populate the personnel number table.
  
  
  When Does It Occur?
  
  During payroll runs or personnel data processing.
  In custom ABAP programs or enhancements where personnel numbers are expected as input.
  In standard SAP HR reports or function modules that require personnel numbers but receive none.
  
  
  Solution
  
  
  Ensure Personnel Numbers Are Passed Correctly:
  
  Check the program or function module call to verify that the personnel numbers are correctly selected and passed into the internal table PERNR_TAB.
  If you are using a selection screen, make sure the selection criteria are correct and return personnel numbers.
  
  
  
  Populate PERNR_TAB Properly:
  
  Before the processing logic that triggers this error, ensure that the internal table PERNR_TAB is filled with valid personnel numbers.
  Example:
  SELECT pernr FROM pa0001 INTO TABLE pernr_tab WHERE <selection criteria>.
  IF sy-subrc <> 0.
    MESSAGE 'No personnel numbers found' TYPE 'E'.
  ENDIF.
  
  
  
  
  Check Custom Code or Enhancements:
  
  If this error appears in custom code, debug to see why PERNR_TAB is empty.
  Make sure the logic to fill PERNR_TAB is executed before the error occurs.
  
  
  
  Review Standard SAP Notes:
  
  Sometimes SAP releases notes or patches related to HR processing errors. Check SAP Support Portal for any notes related to WPI020.
  
  
  
  Testing:
  
  Run the program or payroll with a known set of personnel numbers to verify that the error does not occur.
  Use debugging to trace the population of PERNR_TAB.
