Issue while creating Vehicel Quotation in SAP DBM

Hi Experts,

I have creted purchase order, Goods Receipt and Incoming invoice for a vehicel through /DBM/VSEARCH transaction.

Now i am tring to create the sales quotion for the same vehicel, It is showing an error like" Vehicle item in order not found ".

After that i tried to execute the VMS action for sales quotation in VELO trasaction, I am getting the error like " No reservation for the Vehicle".

Please let me know what would be the reson for this error. Help me how to resolve this, You are rewarded accordingly.

Thanks,
