P1-EXIT Message Flow
The MH-TRANSFER option is used if no changes are to be made to the root object.
In this case, the client wants the root object to be treated like an outbound message,
so it puts the message on the outbound queue:
The GIP notifies the MRP of an outbound root object in the MR group PDU store.
7. The MRP reads the outbound root object in the MR group PDU store.
8. The MRP routes the outbound root object to the appropriate destination.
The MH-REMOVE option is used if the client wants to make changes to the root
object. The original root object is removed from the MR group’s PDU store, a copy
is made, and changes are made to the copy (the object tree form in the GPI Library).
After changes are made, the message is treated as an outbound message and follows
the flow for outbound messages in a NORMAL type gateway.
