PI 7.1 - receive unknown IDOC

Question

hello everyone.
I have the following scenario:
we receive from another SAP system an IDOC that we do not have in our ERP system
example: name: ZDOC.ZDOC1, namespace: urn:sap-com:document:sap:idoc:messages
after receiveing it - we map it to a target service interface:
example: name: ZDOC_TARGET_SI namespace: http://abc
the sender system insist on sending the IDOC in it's original name, and not as a message interface.
in order for us to know the structure of it - we got an XSD - and we make a service interface that uses it:
example: ZDOC_SOURCE_SI namespace: http://abc
the problem is - that on the receiver determination - I must configure the incoming message with the idoc name:
ZDOC.ZDOC1, but the operation mapping maps between ZDOC_SOURCE_SI -> ZDOC_TARGET_SI - so I can not use it in the interface determination.
in short - how can I map an interface when the name & namespace of it are determined for me, but I can't have them in my ESR?
thanks ahead,
Imanuel Rahamim.

Hi Imanuel,
"that on the receiver determination - I must configure the incoming message with the idoc name:
ZDOC.ZDOC1,"
Why do you HAVE to use the same IDOC name? It doesn't make any sense to me.
Can you explain why it has to be that way?
As you might have figured out already, there shouldn't be any problem if you use ZDOC_SOURCE_SI and its name space as the outbound message. isn't it?
In the worst case, If you HAVE to use the same IDOC name, then you have to create a ZIDOC with the same name in your system also and import it in your ESR.
