I've already import a file with 30K customers and everything is fine.
Hi Roberto,
What is the file type you are using? Have you checked if there are no duplicate records in the source file? Also ensure that at the end of the file there are no empty lines.
You can also check if the number format for decimals are OK and dates are also valid dates.
