Anyone can export data with the Power BI connector for ServiceNow, as long as you have been assigned the PBI ADMIN or PBI EDITOR role by the ServiceNow System Admin. To get started, you need to create a data source and assign a name to your connector. Next, the connector allows you to determine who has access to the data you intend to export. You also get to set filters to determine the data sets and fields to export or organize the data based on parameters such as date, issue type, projects, status, etc.
Once you have selected the fields you wish to export from ServiceNow, click “Create” to generate a data source link. Copy this link and paste it into the "OData feed" field on your ServiceNow desktop application. In the new window that opens, enter your ServiceNow credentials and click “Connect” to start the data export.
