IDoc (asynchron) - HTTP (synchron, plain text) - RFC

Question

Hello,
I've implemented the following Business Process inside our PI 7.1:
Reciver           -> Mapping                    -> Sender             -> Mapping              -> Sender
(getting IDoc)     (IDoc to Plain Text)         (sync, HTTP)       (plain text to xml)     (back to SAP using RFC)
My problem is, it works only until the first Mapping has finished and ends before the synchronsous sender.
It's a Java mapping which creats a Plain text containing the POST parameter which are needed for the HTTP
Request (no I can't send xml). The created payload looks the following way:
mid=1&portalid=xxx&key=xxx&mode=live&request=capture&encoding=UTF-8&txid=1&amount=0&currency=EUR&invoiceid=6510672402&id[0]=6510672402&pr[0]=0&no[0]=1&de[0]=6510672402
The error I get is:
could not create BPE proxy for message, no XML object definition found for message [msg id]
It's no XML message, but can't plain text be processed inside the BPM?
AFAIK I need the BPM for ASYNC/SYNC bridge.

Hello all,
I've done the scenary three times on PI 7.1 in different ways and was not able to make it work. I've switched to our old XI 3.1 developer machine and tried there again. It worked at the first try. Don't ask my why, but after exporting repository and directory from the XI 3.1 machine and importing to PI 7.1, it also worked there.
I can't say, what's the reason, but we also had cache problems on the PI 7.1 last days (interface mappings where not found), maybe it simply was a cache problem...
Thanks for your help,
Manfred
