Hi Santosh, if you change anything you should change both the revision number and date.
Revision number = the latest approved version
Revision date = the date the last revision was carried out
But to be honest why create work for yourself, it is not important that you change the author, after all you did not author it. As and when you make changes to documents and procedures then change it to your name one by one.
Regards,
Simon
