About offer and treatment codes
An offer code is the globally unique identifier for an offer. A treatment code is the globally unique identifier for a combination of a cell (a list of IDs) and an offer.
Each offer in Unica Campaign must have a code, and no two offer codes in the same Unica Campaign partition should be the same. An offer code can have one to five parts, which you specify when you create the offer template.
When users create an offer, the Offer Code fields are automatically populated with a unique value from the code generator.
Users can click Regenerate code to have the code generator supply a new identifier, or they can enter a code manually. To override offer codes, users must have the appropriate permission.
The unique combination of a cell and an offer used at a particular point in time is a treatment. Each treatment is uniquely identified with a treatment code.
