SureDone uses the field magentosku to sync to the SKU field in Magento. If magentosku doesn’t have the exact same value as the SKU field in Magento, the two products will not sync.
On import, SureDone automatically fills out the magentosku with the proper value.
When a new product is created, SureDone automatically sets the magentosku to the value of the product’s GUID.
If required, you can update the Magento SKU using the force operation.
There is an additional field, magentolistingid that serves as a unique mapping to the Listing IDs of products in Magento, however this field is not used to sync between the systems. It is there purely for information purposes.
