Hi,

You may have used some ID of the record in the sheet that you are trying to import, which is not existing in the system. Suppose in the product field in the sheet you may specify product_product_1 which might be the id of some record, later someone delete the record, and then if you try to import a product by specifying this ID system cannot find a record with the given id as it is already deleted.

So make sure the record is existing in the database.

Thank
