Updating FM database with excelsheets without creating duplicates
I regularly have to update the company database on FM with excelsheets.
When I add the data from the excelsheet there are always appearing duplicates in FM. I only need to add new companies.
I can set apart the duplicates, but manual deleting takes tooooooo much time.
What can I do do avoid the duplicates while updating?
I am using Filemaker 10 Pro on WINDOWS XP since Mondy,very low experience.
Thank you very much for your help.
