Detailed contact history (UA_DtlContactHist)

The detailed contact history table is written to only if you are using a scenario where individuals within the same cell receive different versions of an offer.

For example, members of the same cell might receive the same mortgage offer, but the offer can be personalized so that Person A receives a 5% rate offer, while Person B receives a 4% rate offer. Detailed contact history contains one row for each offer version that an individual receives and one row for each control cell based on the offer versions they would have received.
