Only import records, if the ID Number is different
I want to create one large database, in wich I want to import records from several other filemaker files. The number of records in that files will increase permanently. That's why I gave any record an ID element. And here the problem appears:
I only want to import the records, if they don't have the same ID than the records, wich are already in the large database. Until now, I imported all records from every file any time and deleted the doubles with a script. But this is not a sustainable solution.
Has anybody an idea, how this could be done ?
