  Authorization Check: Ensure that the user has the necessary authorizations to modify the sales order. This may involve checking roles and permissions in the user profile.
  Consult Configuration: If the issue persists, consult with your SAP Basis or configuration team to review any settings that may be preventing changes to sales orders.
