In order to apply the commitment conditions to your campaigns you have to fill the field: Commitment on the media campaign.

Only one Commitment

If you have only one matching commitment for your Media Campaign the Commitment will automatically be linked when you create the campaign. If this Campaign is an exception, you can remove the lookup manually, otherwise you don't have to do anything.

Multiple possible Commitments

You can assign Commitments manually or alternatively use the Commitment Selector Button which will filter for only valid and matching Commitments (Version 2.92 and up). Open your Media Campaign and click on the Commitment Selector button. This button has to be enabled by your administrator. 

The next window will offer you a list of Commitments. Pick the correct and hit Save.
