• What is the cause and solution for SAP error message WRF_AT004 - Enter at least an activity status ?

  SAP Error Message:
  
  WRF_AT004: Enter at least an activity status
  
  Cause:
  This error occurs when you are trying to save or proceed in a transaction related to work scheduling, personnel administration, or time management, but you have not entered any activity status for the relevant period or record. The system requires at least one activity status to be maintained to process the data correctly.
  Activity status typically refers to the status of an employee's activity or employment (e.g., active, on leave, training, etc.) during a specific period. Without this, the system cannot determine the employee's work status and thus throws this error.
  
  When does it typically occur?
  
  When maintaining or changing employee master data (e.g., infotype 0007 - Planned Working Time, or infotype 0001 - Organizational Assignment).
  During time evaluation or personnel actions where activity status is mandatory.
  In personnel planning or work scheduling transactions where activity status is required to define the employee's availability or work condition.
  
  
  Solution:
  
  
  Enter at least one activity status:
  
  Go to the relevant infotype or screen where activity status is maintained (e.g., Infotype 0007 or 0001).
  Enter a valid activity status for the period in question.
  Save the data and try to proceed again.
  
  
  
  Check the validity period:
  
  Ensure that the activity status covers the entire period required.
  If there are gaps, fill them with appropriate activity statuses.
  
  
  
  Verify configuration:
  
  If you are unsure which activity statuses are valid, check the configuration in transaction SPRO under Personnel Management ? Time Management ? Work Schedules ? Define Activity Types and Statuses.
  Confirm that the activity statuses are correctly defined and assigned.
  
  
  
  Check for missing infotypes:
  
  Sometimes, the error arises because the system expects an infotype that is missing.
  Use transaction PA20 or PA30 to verify the employee's master data and ensure all required infotypes are maintained.
  
  
  
  
  Related Information:
  
  Infotype 0007 (Planned Working Time): Often where activity statuses are maintained.
  Infotype 0001 (Organizational Assignment): May also require activity status for certain actions.
  Time Evaluation: Activity status is crucial for correct time evaluation results.
  Personnel Actions: When processing hiring, transfers, or leaves, activity status must be maintained.
  
  
  Summary:
  
  Cause: No activity status entered where required.
  Solution: Enter at least one valid activity status for the relevant period.
  Check: Employee master data, infotypes, and configuration of activity statuses.
