This error indicates that you are trying to modify the arrival details of a transportation order or shipment that has already been assigned a schedule. When a schedule is assigned, certain fields become locked to maintain data integrity and prevent inconsistencies.

  Consult with Stakeholders:
  
  If you are unsure about the implications of changing the arrival details, consult with relevant stakeholders (e.g., logistics, planning teams) to understand the impact of such changes.
  
  
  
  Use Transaction Codes:
