• What is the cause and solution for SAP error message HRPAYAT_PAYROLL_ST421 - Children saved in IT0042, but without valid IT0021 ?

  The SAP error message HRPAYAT_PAYROLL_ST421 indicates that children have been saved in Infotype 0042 (Family/Dependents) without a valid entry in Infotype 0021 (Family Member/Dependent). This situation typically arises in the context of payroll processing, where the system expects a valid relationship between dependents and their corresponding family member records.
  Cause:
  
  
  Missing or Incomplete Data: The error usually occurs when there are entries in Infotype 0042 that do not have a corresponding valid entry in Infotype 0021. This can happen if:
  
  The family member's data was not entered or was deleted.
  The relationship type or validity dates in Infotype 0021 do not match those in Infotype 0042.
  The employee's data was not maintained correctly.
  
  
  
  Data Consistency Issues: The system enforces data consistency between these infotypes to ensure that all dependents have valid family member records.
  
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Infotype 0021:
  
  Go to the employee's master data and check Infotype 0021 for the relevant employee.
  Ensure that there are valid entries for all family members/dependents that correspond to the entries in Infotype 0042.
  
  
  
  Maintain or Correct Data:
  
  If there are missing entries in Infotype 0021, create them. Ensure that the relationship type, validity dates, and other required fields are filled out correctly.
  If there are incorrect entries, correct them to ensure they match the dependents listed in Infotype 0042.
  
  
  
  Review Validity Dates:
  
  Ensure that the validity dates for the entries in both infotypes align. If a dependent is valid for a certain period, the corresponding family member record should also reflect that.
  
  
  
  Reprocess Payroll:
  
  After making the necessary corrections, reprocess the payroll to see if the error persists.
