  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?
