Tell Junipeer which Magento attribute to use for some product details, such as description, EAN and unit.
Each row connects:
a product detail (Description, Ean, ShortDescription or Unit), and
the Magento attribute key where it should be saved.
Good to know
Without a key, that detail is not set when products are created or updated.
Type the key exactly as it is in Magento – same spelling and same upper/lower case.
These are the fields marked [def] in Fields to update.
