Dear Michael,

You may migrate your transaction to SIS at any billing stage. So yes, if rejection stage 1 was done outside of SIS, the following rejection stages can be done in SIS. However, once a transaction has been responded to in SIS, it has to stay there (please see also the FAQ section on the SIS website). So in this case, rejection stage 3 and any following correspondence must be done in SIS if you have submitted stage 2 rejection in SIS.

In addition, the IS-Validation is set up to check if the carrier you are rejecting with RM stage 2 has already migrated at the time of its RM stage 1.

Please note that when you create your RM stage 2, you have to refer to the RM stage 1 (your invoice date, your invoice number, etc.). Hence SIS is validating if the carrier who has sent you the RM stage 1 was a migrated or a non-migrated carrier at that time.
