E filling of tds return

I am trying to file TDS return , but following error is coming.

T-FV-4267 Invalid PAN. For Lower/No deduction 10 digit valid PAN should be provided.

Reason for this error is

We have make payment of Foreign Royalty and for the same we have deducted TDS,  Deductee being foreign company is not having PAN Number.

On searching on net i find that PANNOTAVBL is be written and Tds is to deducted at 20%. I have tried the same but the above error is coming.
