Hi,
You can do it by creating your JSON object first in your order tab. Create a Javascript columns where you add all the values you need in your JSON object.
Then display in a column the JSON objects only from the order you need (based on the filter you use), join these JSON object (JSON Payload) in another column, and then in your invoice tab use a lookup to retrieve the JSON Payload.
I think this is what you need, if not let me know
