Is anyone utilizing Channel Advisor and successfully using suite promotions? Channel Advisor does not appear to support the feature and i am not able to import orders as Channel Advisor tries to set promocode and couponcode fields that are disabled by Netsuite when Suite Promotions are enabled. Channel Advisor sets the field dynamically so i can't even intercept it and apply them before the record submits.

Have you tried creating a custom field to flag CA orders so that you can trap them in a UES to do what you need to do before the sales order is submitted?

I don't believe CA has any concept of suitepromotions. I do know that any aftersubmit triggers on a sales order tend to cause conflicts with the connector, and that's why there's a feature/checkbox to 'disable event triggers on orders.' Could try that, but if core NS functions have disabled those fields, that's probably a hard clash. ca-Order-class.js is where the coupon/promo code reference lives. Is that a locked script on your end?
