tds return of transporters

I am working with a logistics(transport) company, we enter into transport contracts with the sub contractors for serving our clients.

Now as per the amended provision if

1. the transporter furnishes PAN no tds is not to be deducted

2. if he does not furnishes PAN, tds is to be deducted

Now

While preparing tds return

I will not have to provide detail of 1 above as no tds is deducted

and as regards 2 above I cannot prepare return since I do not have their PAN No.

Kindly advise how should I prepare the return, specific to this case.
