David has inherited a new Adobe Marketo Engage instance.

Two fields that David would use for this purpose are Person Source and Original Source Type. These are system-managed fields that capture information about how a person was created in the database. Person Source indicates which channel or method was used to create the person, such as Web Service API, List Import, Sales Insight, etc. Original Source Type indicates which type of source was used to create the person, such as Web Page Visit, Web Form Fillout, Sales Generated, etc. These fields can give David a high-level view of the lead sources without relying on user input or smart campaign logic. Registration Source Type and Acquisition Program are not system-managed fields and may not be populated or accurate for all leads.
