Offer or offer lists that are retired in Campaign can no longer be used in Optimize. Retired offers or offer lists appear grayed out in the user interface and are noted with “(retired)” next to the offer name. Specifically, they appear grayed out in the Select Offer(s) window when choosing an offer or offer list for use in an optimization rule.

Offers that are used in optimization rules can be subsequently retired. Note that Optimize sessions are considered valid, even if they have rules that depend on retired offers; however, you cannot create new optimization rules using retired offers.

Optimize prefaces rules that contain retired offers or offer lists with the word “Warning” on the Rules tab. You may want to edit these rules to eliminate the reference to retired offers or offer lists or delete this rules if they are no longer necessary.

For more information on retired offers and offer lists, see the IBM® UnicaCampaign User’s Guide.
