Stop duplicates using unique id
We have 5 people with ipads using FMGo.... they each have a copy of the main database and add to it each day.
Every entry has a uinque id (VisitID) for each person. At the end of the day we are getting them to email their database back to 'base', where it is imported into a pc running FMPro.
Is there a way of preventing any duplicates on the pc's database using the unique id (VisitID)?
Thanks in advance.
