Hi @anitha1280,

Have you tried a no-code platform instead? You can get a lot more flexibility in connecting DevOps to ServiceNow with an out of the box syncing tool like Unito. Here's an integration guide for ServiceNow and Azure. It syncs a table from SN to a project in ADO with updates between records and work items.
