Dear Andrea,

The Import process is very complicated and you need experience to do It.

You need to find an expert  to create for you the links between the columns in the excel file and INtools columns.

You can use the ERD document from INtools documentation to learn about the structure of the database.

To prepare links is not part of routine support , it’s a service and needs the database and

the Excel files reviewed .

First view the source from import to make sure this line is out of the import area

If you can see the row for this line make sure you don't have already the same line num and the flag "update" in the importrt preferences uncheck .

If it's not the case send me the excel file and the log from the import.
