The stimulus is the identified reason for which a customer places an order. Since there can be multiple stimuli, the ATG data warehouse allows for stimulus groups.
The Stimulus query subject lists stimuli. The Stimulus Group query subject identifies all possible combinations of stimuli. The Stimulus Group Members query subject identifies stimuli with the groups of which they are members.
The Stimulus regular dimension includes two hierarchies, one of which includes the stimulus group data, the other only the Stimulus and Stimulus (All).
