In this tab you can select which suppliers to enable for the export process.
By default every supplier will be enabled as per Idealo specifications. Click on the green mark to disable them or select more than one supplier with the dedicated checkbox if you want to disable more than one at once.
Using the Prestashop classes, the summary product table allows to perform some quick searches or to massively select and deselect suppliers. By default, as per Prestashop standard, the module will show 50 results that can be extended up to 1000.
