Multiple revision of service tax return

Revised return can be re revised any number of time if its within the time limit of originally filling it.

To my knowledge there is no such restiction other then time limit of original return for revising ST-3, if i am wrong kindly correct me.

Mr. Tushar is correct in law i.e. it seems there is no provision restricting re-revision of revised service tax return. But i tried it once few months back and the ACES System showed some error.

So, if someone has successfully filed the revised return for more than once, then kindly update here.

Can anyone update about how to file multiple revised return as per Rule 7B of Service Tax Rule, within 90 days from the date of filing of the original return.
