Dear friends,
I tried the Blog Amit suggested and thats also what Indrajit said. This seems to work 
Thank you for your solution!
I just have one question is there also a possibility to correlate the Idoc number?
In my scenario I send an Idoc and get a response from a webservice and map the response to an ALEAUD Idoc. Is there a possibility to keep the original Idoc number and send it back via ALEAUD?
Your help would greatly appreciated,
Kind regards,
John
