Hi Sahadev,
Message type: SHP_OBDLV_CREATE_SLS
Basic Type: SHP_OBDLV_CREATE_SLS01
Process code: BAPI
Distribution Model: Add message type mentioned above using 'Add BAPI' tool bar push button with Object name 'OutboundDelivery' and Method 'CreateFromSalesOrder'.
With the above settings, SAP will call 'BAPI_OUTB_DELIVERY_CREATE_SLS' internally to create a Outbound delivery from Sales order with Inbound Idoc.
