Can I Do Both Syncs on the Same Connector?
Yes. You will need to provide FarApp with a custom field that you use to determine which type of sync a given SKU will use. A SKU cannot sync using both types of sync. It must do one or the other. Customers usually make this custom field either a list (where you select from either a "Full Product Sync" or "Price/Qty Sync" option for each SKU) or a checkbox (ex: custitem_full_product_sync where true = do full pruduct sync, and false = do price/qty sync).
Why Would I want to Do Both Syncs on the Same Connector?
It is up to you. This works well for some customers where they want to use Price/Qty sync for their existing SKU's on a storefront. They then use Full Product Sync for new SKU's because they create the new SKU's entirely in NetSuite and let FarApp sync all the product data. It is unusual to do both types of syncs for the same connector and FarApp does not consider it best practice. It can lead to more complex mappings than normally required.
