How do I export an order so someone else can alter the data and send it back to me?
You would use the Change Owner feature instead of export for that purpose. In the lower left area of the screen find the Order Owner drop down box. Select the person you wish to transfer the order to and then save.
Currently you have to let the person know to look for this order but at some point we will be looking to create an in-app alert when an order is transferred to you.
