Update records with Data entity import

Hello,

I have exported the Products with Standard Data entity successfully.

Then I tried to modify Product number to upload / create new products. This also was successful.

My problem is that I can't update a value with import.

With the same product that I imported / created in previous step, I changed some values in Excel file (Like description, some checkboxes), when I click import, it says records successfully updated, but when I go product details nothing is updated.

What can be a reason?

Thanks.
