If you're getting the following error message :
Cancelling flow execution because rate value is not positive percentange. Actual value found: 0.00
If you're creating a new item, you'll need to add a % sign to the rate, because our flow is triggered when you submit a record, but NetSuite appends the % after the record is saved.
If this doesn't solve your issue, let us know so that we can improve this answer!
