This key figure indicates the net (or delta) unit sales due to total tactic impact (which refers to all combinations of tactics and tactic types used in an offer), independent of all other causal factors such as temporary price reduction.

This quantity can be combined with other delta unit sales quantities to determine the expected unit sales including the effect. For example, adding the net unit sales due to the total tactic impact to the base unit sales quantity calculates the expected unit sales in which the effect of total tactic impact has been taken into consideration.
