• What is the cause and solution for SAP error message WK006 - Substitution for & ended ?

  SAP Error Message:
  
  WK006 Substitution for & ended
  
  Meaning / Cause
  The message WK006 Substitution for & ended typically occurs in the context of SAP Workflow or Substitution Rules (often in the context of Business Workplace or HR substitution scenarios). It indicates that the substitution period or rule defined for a user or object has ended or expired.
  More specifically:
  
  The substitution rule that was active for a user (e.g., a delegate or substitute approver) has reached its end date.
  The system is informing you that the substitution is no longer valid because the defined substitution period has ended.
  This can happen if a substitution rule was set up with a validity period, and the current date is beyond the end date.
  
  
  When does it occur?
  
  When a workflow or approval process tries to find a substitute for a user, but the substitution rule is no longer valid.
  When a user tries to act on behalf of another user, but the substitution period has expired.
  When checking substitution rules in transaction SBWP (Business Workplace) or POWL (Personal Object Worklist).
  
  
  How to check / verify?
  
  
  Check substitution rules:
  
  Use transaction SBWP ? Settings ? Substitution to view current substitution rules.
  Or use transaction S_BCE_68000174 (Substitution Rules) to check validity periods.
  In HR scenarios, check PA30 or PPOME for substitution or delegation assignments.
  
  
  
  Check validity dates:
  
  Verify the start and end dates of the substitution rule.
  Confirm if the current date is outside the validity period.
  
  
  
  Check workflow logs:
  
  Use transaction SWI1 or SWIA to check workflow instances and see if substitution was attempted.
  
  
  
  
  Solution / How to fix
  
  
  Extend or create a new substitution rule:
  
  If the substitution is still required, create a new substitution rule with a valid start and end date.
  Adjust the end date of the existing substitution rule to a future date if appropriate.
  
  
  
  Remove or update expired substitution rules:
  
  If the substitution is no longer needed, remove or deactivate the expired substitution rule to avoid confusion.
  
  
  
  Inform users:
  
  Notify users that the substitution period has ended and they need to act accordingly.
