I am working on triggering the BPM start event from custom UI5 application. My requirement is Action(Submit Button) from custom UI5 application should trigger the BPM start event automatically. The Submit button in custom UI5 application tries to post some data through BPM Odata service. After that, it should trigger my BPM start event automatically. My doubt is how to use the BPM OData service to initiate the start event in BPM process. How to use this service in BPM especially in Start event in BPM process.
