• Message number: 121

• Message text: No leg determination possible since shipping types VL and NL are missing

What causes this issue?

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

Leg determination can not be carried out because you have not
maintained shipment type VL and shipment type NL in the shipment
header. These are necessary, however, if the legs to be determined are
to have a shipping type.
Shipment type VL and shipment type NL are necessary, if the following
requirements are to be met simultaneously:
- Leg determination type '2' or '3' are active in
the shipment type of your current shipment
- The leg indicator in the shipment header is set at '2' (main leg),
'4' (direct legf) or '5' (return leg)
- Legs exist (either manually entered, or determined via a route)
