Orders stops are grouped by Accounts. If you have multiple orders from different accounts at the same location, the orders will be grouped for each account independently.
Troubleshooting the stop grouping
1) Verify in the Account order profile if you are grouping on Address Line 1 or Address Line 1 and 2. If you are grouping on Address Line 1 and 2, verify that Address Line 2 is entered correctly.
2) Verify if ID verification and/or a COD is requested on the order. If at least one of the option is set in the pickup or the delivery workflow, the delivery stops will not be grouped as they need to be done individually.
3) Verify if one or more of the reference fields are setup to be updatable by the driver and if they are, are they setup as required for pickup/delivery/or both. If this is the case, the stops at pickup/delivery will not be grouped.
