HTTP into PO fails with HTTP400


I have internal system that needs to send XML messages to another internal system and I am using SAP PO 7.5 to facilitate this. So send a XML message to another system. Both use HTTP..

I have set up the HTTP Sender and the HTTP Receiver communications channels and configured an iFlow/ICO.

I can test this OK within NWA Test Tool but via Google Postman it fails with a HTTP 404 Page not found

I am on SAP PO7.5 and have set the URL as per this Help & interface=TransitionTaskCreate_Out


Unencoded it looks like this - but I am posting the encoded version & & interface=TransitionTaskCreate_Out

Sorry this editor is translated the last part of the URL.... & & interface=TransitionTaskCreate_Out

    Hi Jonny!

    Since you work with SAP PO 7.5, you use java HTTP_AAE adapter, not plain ABAP-based HTTP adapter used for communication with Integration Engine. So, your query string should look like this:

    Hi Evgeniy !

    thankyou very much that is the solution. I really do appreciate it.

    I went back to the SAP Help page and yes it does sort of say this further up the NW 7.5 chapter - but then I tried to find on the keywords HttpAdapter / HttpMessageServlet and the only page I found so far was a NW 7.3 page - I gave up in the end looking as you provided me with the solution. So i will I remember for next time and hopefully this will be useful for others too.

    JAVA : HttpAdapter/HttpMessageServlet

    ABAP : sap/xi/adapter_plain

    Cheers !
