@Arun_Manoj you will have to go look at the SAP Signavio API documentation and look at which APIs/Rest messages get the data you need. Generally, customers pull their processes from Signavio into the Business process table in ServiceNow so they can map it to applications, services, risks, and controls
Once you understand the data you need from Signavio you would then create a spoke in ServiceNow for it.

If Signavia provides and OpenApi documentation you can have ServiceNow automatically create the spoke for you.
Then you will need to build a scheduled job to pull the data from Signavio at a defined interval to update any of the changes made in Signavio, this is called a delta file and would include only the changes since the last time the integration was run.
