In your order flow filters, you want to add a Rule set like this:
Please make sure the Rule is set to "Not Matches" as seen above, and enter the following text into the value field:
By using the settings above, any order with the following tags will not import into NetSuite.
However, for orders in Review, if the order tag is updated to "nofraud_updated_pass", then the system will capture the order's update and will import the order into Netsuite.
Please note, the scheduled flow must be set to "Filter Orders By" = Last updated time (as seen below), so that it will detect the order updates from Shopify.
