How to use the Cireson Asset Import Connector
The Cireson Asset Import Connector is one of the solutions contained within the Cireson Asset Management Stream of products and allows for Asset Administrators to take the guesswork out of importing external data into System Center Service Manager. This app allows any out-of-the-box CMDB data, or any information in the Cireson Asset Management app, to be imported from external CSV, SQL, ODBC or LDAP sources of truth, exposing an intuitive interface that provides the ability to map columns and schedule imports when required.
