How are products matched across configurations in a multisource signal configuration?

To establish the connection between the configurations, the multisource signal configuration refers to the lead configuration's Product name field. Every product has Product name and Product term fields. The Product name field is used to connect the Product-Event Combination rows from the underlying configurations.

Review the product names in each configuration and decide which ones you would like to have matched. You may need to rename the product, particularly in the secondary configurations, so that the name matches. If you do rename products, you also need to refresh the configurations before creating your multisource signal configuration in order for the rename to be in effect.
