We built custom VF page for data import into a custom object.Also written import controller class. When we try to import data for multiple times it is creating duplicate records instead of updating the existing records(per logic).What could be the reason?

Question

The logic written here is to update existing record instead of creating new record when multiple imports are done.

Hi,   Double-check your logic, The System will do what you have instructed to do. So debug carefully and find the root cause of the issue.
