We're trying to create sales orders via the Boomi NetSuite connector. The customer is under subsidiary 1, the assembly item we're trying to put on the order is under subsidiary 1, subsidiary 2, and subsidiary 3 which is a child of sub 2. One of the components of the assembly item is under subsidiary 2 & 3. And it's not allowing us to put that Assembly item on the order because of that component item. Is that native NetSuite functionality? Subsidiary 1 & 2 roll up to the same parent subsidiary...

You might try a test duplicating the item... I've had sub issues on the item record inexplicably before
