What report will show the routes along with sales order number.
From sales order line item you should link Delivery item i.e. VBAP - to LIPS where VGBEL in LIPS is sales order no.
You may get no. of deliveries for an item which is correct.
Then from LIPS you will get to LIKP table and get ship to party for these deliveries.
And using VBFA you can check shipments for this order line item using document category(VBTYP ) Field.
Thanks & Regards
As far as i know there is no standard report which shows the route along with the sales order number.
You may have to create a Query using
VBAK- sales order header and with VBAP table.
Link the VBAK-VBELN to VBAP-VBELN and get the details of VBAP-ROUTE
Or directly using the VBAP table and field VBAP-ROUTE you can get the details like sales order number (VBELN) and Route (ROUTE)
