## About this task

The Service Graph Connector for Microsoft Excel uses the configuration available in the Excel SGC Class Mapping \[excel_sgc_class_mapping\] table to determine the best ServiceNow
Configuration Management Database (CMDB) class each configuration item (CI) should be placed into. You can modify these settings at any time but it is best to review the current configuration before running your
first import.

## Procedure

1. Navigate to AllOT Manager AdminExcel SGC Class Mappings.
2. Review and update the following fields in the class mapping records as needed.  
   {#review-class-mappings-sgc-excel__table_b2z_zgx_cdc__entry__2}

   | Field | Description |
   |-|-|
   | Source Class | The class of the source CI. |
   | Target CMDB class | The expected ServiceNow class for the CI. |
   | OT Device type | The category type that the OT device is classified as. The device type is also the function that the device plays on the OT network. For example: An IT device, such as a server, can be converted to an OT device, and the function it plays on the network is an HMI. Therefore, its class is server and its device type is HMI. Note: In some cases, there are OT devices with no OT function or OT devices where the device type is unknown. For OT devices with no OT function, select No OT Function. For OT devices where the device type is unknown, select Unknown. |
   | Allow OS classification | When set to True, if an operating system is found on the CI, the target is switched away from the target CMDB class to a ServiceNow class that matches its OS. |
   | Active | When checked, the class mapping is set to Active. |
