When you add multiple data sources to an IT Discovery Tool process, there is a possibility that normalization will gather duplicate entries for the raw data. You can specify deduping rules to eliminate duplication of data.
Note • Deduping rules do not apply to data mashup data sources. Normalize CM is no longer available.
To specify deduping rules:
1.
Click the Details link (Process Details). The Data Source pane expands to include priority information about each data source.

Click the Deduping Rules link, located at the bottom of the expanded Data Source details pane, beneath the Add Data Source link. The Deduping Rules dialog opens (Deduping Rules).
3.

Select a deduping key from the Deduping key drop-down. The available deduping rules are:
