I would prefer to create the shipments by addining the Deliveries without having the routes entered in the Deliveries and then using user exit update the Routes into the Deliveries using the route from shipment header, but the problem I am having is if the Route is not entered in the Deliveries those deliveries are not being selected in the shipment document because the indicator "Transportation Planning status " VBUK-TRSTA " in the deliveries is not set untill the Route is entered.
One option I am thinking is to use a default route so that Deliveries are set for Transportation planning relevance and then update the correct route using the user exit from shipment header
Any suggestions ?
