Why can’t I modify the column labels for secondary configurations in a multisource configuration?

When working with a multisource signal configuration, you cannot edit the Product columns originating from a secondary configuration. These columns are recreated with each refresh with a prefix that matches the secondary configuration label defined in the multisource signal configuration.

To change the labels:

1. Change the labels for the secondary configurations as described in Edit the multisource configuration.
2. Refresh the multisource configuration.
