Configure multiple receivers with identical requirement so as they work independent

Question

Dear experts,
I am configuring an outbound scenario.Requirement of mapping is INVOIC.INVOIC02 ->  ASC810(5010) ie invoice ANSI file
My SAP R/3 triggers an invoice and a file is send to AS2 reciever.
First flow i completed for one customer where i created an inbound service interface.In integration flow i configured the idoc sender channel
and as2 receiver channel.It  worked for me.Here also one thing to notice isi created integration flow for sender giving INVOIC.INVOICE02 in interface (top part).
Now same requirement is for another  customer but when i tried to create a new integration flow and gave INVOICE.INVOICE02 in interface
,it doesnot let me create saying integration flow already exist.Then i took suggestion from someone and used + sign to add more recievers
and communication channels.
It works though but on triggering sap invoice both communication channels have started to work together but i want to make them work independently.
How to handle this scenaio.
I have created only one inbound service interface for this as for outbound i am using INVOIC.INVOICE02.
Thanks in advance.

Answer 1

Yes using RCVPRN field for each reciever i could control that.Also we need to maintain multiple entries if this scenario is common to many customers.But drawback felt was in terms of content organisation.Suppose i created INVOICE02 in interface and QUA in business system in first scenario.Now i need to do same thing for second scenario,then i need to touch first scenario and add an entry for second scenario.This is totally making overall content orgainisation difficult to understand.
Also in some scenarios EDISeparator channels started triggering for multiple senders if ex Invoice is recieved from customer A,then channel B is also trying to accept.There we had to declare uniques names to sort out.
