Connect loads can ONLY have changes made prior to the load being picked up.
If the dispatching company needs to make changes to a load that they sent to the receiving company, they need to reach out to the receiving company and have them delete the connect load in their system.
The dispatching company than needs to unassign the carrier, save the load and re-assign the carrier. This will create a new, corrected load in the receiving company's VH system.
