2496230 - Response XML For A2X And B2B Web Services


Response XMLs for A2X & B2B web services in SAP Business ByDesign.

No Response message shown in External Interface (API) tool i.e. SOAP UI for B2B web services like Advanced Shipping Notification WSDL.

However, the Response message is displayed in External Interface (API) tool i.e. SOAP UI for A2X web services.


A2X services are Synchronous services, in that the response is send back in the same call. Essentially the concept is A2X service is for UI consumption, synchronous accesses and normally user get error message right away if something wrong, and user should be able to consume these service directly if required.

Whereas B2B services are Asynchronous services, no response is sent back in the same call, but response can only be viewed via business communication monitoring View in Applciation and User Management Work Center. Further, A2A or B2B process, in major case, will include forward error handling etc and need involve middleware.


This is the standard protocol behavior.
