[RegAffairs]Site representative

["Yongliang Tou" <yongliang.tou@gmail.com>]

Dear all,

Is there any regulatory problem if one site design two site 
representatives by two different address name?
If there is, would anyone give me a reference for this?
And if this company want to correct this and use only one site 
representative for the site, what materials should be submitted to 
explain this problem?

Thanks.
