Hi Wilbert,
This is my question is a possible to have two or more AS2 ID in the same Party and routed in Seeburger adapter?
-->> One party can have only one unique AS2 ID. so for two AS2 ID you need to create two party.
As per my understanding you want to send similar structure to other country which have different AS2 ID, so you need to add one more receiver in your ICO and route the message to new party.
regards,
Harish
