A tactic can be created and saved without any creatives linked, however it must be linked to at least one creative before it can go live. A creative can be linked to any number of tactics, and a tactic can have multiple creatives linked. You can also link and unlink creatives at any time once the tactic is saved, regardless of whether it is running live or not.
Linking Creatives from the Creative Panel
- Open the media plan that contains the tactics you want and select those tactics.
- Click Creative.
- Select the creative or creatives you want to map to the selected tactics.
- Click Map Selected.
