Explanation
- two external systems are called during message processing
- there are two extcall's stops to which we can return during processing
- if error occurres
- before first request to external system 1 then then next processing try will start from the beginning, same as new message arrives
- during communication with external system 2 then next processing try will start from extcall1
- after successful response from external system 2 then next processing try will start from extcall2
