Running strategic segments
You should re-generate strategic segments if the contents of your datamart have changed. To re-generate a strategic segment, you run the flowchart in which that segment was created, in production mode. The Enable Output setting in Test Run mode has no effect; strategic segments are output only in production mode.
When a Create Seg process is re-run in production mode, the existing strategic segment created by that process is deleted. This means that any users of the existing strategic segment (including global suppressions) might see an "invalid segment" error if the new Create Seg process run fails to complete successfully, or while it is still running.
