I have a CloudPage form. Is it possible to update a record already exist in the target DE? Let's give you an example:
The target DE has a Primary Key email. Every other field is nullable. Person A goes to the form and fill out the form with email address [email protected]. After a while he goes again to the form and fills out the form again with the same email address [email protected]. But with other data then the first one. Is it possible he overrides the DE and puts the last filled in data in the target DE?
