Refresh: Refresh is used to get the latest order status from ERP, where ERP order is already available. As per current understanding it only works with P21
Re-Submit: This is available to all the ERPs except P21 as it helps to re-submit the failed orders from Admin Portal. Only CIMM2 web reference is available
