Two or more price levels are required. The General Group in NetSuite should pass as "ALL GROUPS" in Magento. When pricing is passed during the product export, the ALL GROUPS customer group will be selected on the product.
Resolution: When mapping the Price Levels in the Product Flow Advanced Settings, replace the Magento 2 Customer Group ID that represents the General Group with the All Groups Magento 2 ID. This is 32000.
