How to convert WSDL to O data service to start a BPM Process

[former_member39268]

Dear Experts,

I am new to SAP BPM and working on a small BPM Process demo. I have 2 step process in which process triggers and a human task is assigned to a user. UI is being developed by other team on SAP Gateway server.

In my demo, I am manually triggering the process from NWA.( I have defined event trigger message in my process).Process gets trigger successfully. and I have wsdl generated as well. Now ask is, SAP UI5 Team wants to trigger the same process through Odata service. ( I have wsdl as web service which needs to be modified so that UI team can use it as odata service).

I was going through blogs on SCN, we have a standard BPM Odata service to start a process, I want to know if you have any links/docs step by step how we can achieve the same in my current scenario. One challenge I have is, UI team is not accessible to me. I have defined two parameters ID and NAME in my wsdl, for which I manually entering some value in NWA to trigger the process.

Sorry for my silly question

Thank you

Regards,\

Ravi

Hi Jun,

Can you please below attached screenshot, placeholder looks ok.( what name I should put for vendor( I have kept domain name for the company i.e ngco.com).

Also I have attached wsdl for your reference wsdl.txt.( with this wsdl i am able to trigger the process from NWA)

I was missing correct name for placeholder" vendor".
