Problem Note 51805: SAS® Real-Time Decision Manager campaigns sometimes vary in repeated tests despite the use of identical input
The A/B Test node in a SAS Real-Time Decision Manager campaign uses a generated random number to direct incoming customers into either a champion group or a challenger group. In some instances, the same customer using the same input data receives different group assignments from the node during different executions of a given campaign. This behavior is not treated as an error condition by the product. However, the behavior is unexpected.
