Hi everyone, I have a process model inside application in server runn

Hi everyone,

I have a process model inside application in server running on Appian 7.0 and I want to call a sub-process in that process but it's server is running on Appian 7.10. Is there a way to trigger an application from another server, without migrate versions? Something like calling a web service or something?

Thanks in advance,
Tiago

I think you can try this way. Publish the process model as a web service which is from Appian 7.10. In Appian 7.0, use "Call Web Service" node to call the 7.10 process model. Hope this helps.

Ok I got the idea, but this will work? Have you tried it before? If so, how can I publish a process model as WS? Can you help me with that? Thanks.

You may want to publish your process model as a web-service.

Can I pass paremeters (like process variables) from process in 7.0 to the process in 7.10 that is called by WS?

Tiago, I have tried with external systems and it worked. As suggested by practitioners above, you can go through the link to configure a web service and publish model as web service.

Hi Tiago, Yes you can pass parameters. But, the parameters have to be simple data- types. CDTs cannot be passed to process model published as web-service.
Also, the process model which is exposed as webservice will be called asynchronously. You will only get the processId in output. No other data can be captured in the output.
