Rakesh,
The Means of Transport gets assigned to a PO Line item based on the Std. Validation Check : PO_TTYPE_ASSIGN.
The logic for this Check is as given below :
If the purchase order item does not contain a means of transport, SAP SNC assigns a means of transport to the purchase order item as follows:
- If a transportation lane exists between the ship-from location and the ship-to location, SAP SNC assigns the purchase order item a means of transport that is assigned to this transportation lane.
- If the purchase order for the ship-to location contains an address but no location ID, or if SAP SNC cannot find a transportation lane between the ship-from location and the ship-to location, SAP SNC assigns the purchase order item a means of transport that is assigned to the transportation lane between the ship-from location and the customer location.
- If SAP SNC does not find a means of transport in step 1 or step 2 but the purchase order refers to a contract or a scheduling agreement, SAP SNC assigns the item a means of transport of the transportation lane that is assigned to the contract or the scheduling agreement. If multiple means of transport are assigned to a transportation lane, SAP SNC uses the means of transport with the longest transportation duration.
Now coming to your query, can you explain where are you chnaging the Means of Transport - Is in the SNC TLane ?
