Hi Srinivas,
Please try to maintain/Check the scheduling for sales document type - DL in below path
Logistics Execution
- Shipping function
- Basic shipping functions
- Delivery Scheduling and Transport Scheduling
- Define Scheduling by Sales Doc.Typ
For Delivery type - NL , Default Sales doc type is DL
Once you maintain scheduling the document type then Route and delivery scheduling works in STO deliveries
Thanks
