In Adobe Analytics, this dimension appears two ways: as Ad length (variable) (collected directly from a.media.ad.length) and as Ad length (a classification derived from the Ad dimension). If you use the classification, you are responsible for populating and maintaining its values using Classification sets. Using Ad length (variable) requires no classification maintenance, but you lose the guaranteed 1:1 relationship between the ad length and the parent Ad dimension. Use whichever component your implementation workflow best supports.

Dimension items

Each item is the literal ad length value, in seconds, reported on ad start.
