HI Rajkumar ,
go to TCode : /n/scwm/tu -> create -> (enter the details of truck no and which delivery it is processing , select inbound ) -> enter -> save
copy (EWM Inbound delivery no ) -> /n/scwm/tu -> search the created truck -> select the truck header line item -> assign delivery immediately -> paste on "Document no" field -> execute -> save
I hope your issue will get resolved .
Best Regards
Pratyush
