Two user with same profile and role having different authorization

Question

Dear All,
I have very strange case of authorization . We have a new abap developer in our company . Her profile as copied from an exiting abap developer's profile in Development system. But she don't have authorization for lot of transaction that the existing user have. I checked the profile tabs , role tabs . then done the user compare for all the roles , but of no use.
I did a compare of the two uses using S_BCE_68001430 and could see is that the existing abap user is having authorization starting with T_PXXXXXXXX that is giving him extra rights. These authorization is not present in any of the existing role he is assigned to (checked using S_BCE_68001396). The authirsaction in the roles start with T-DXXXXXXXX
Will appreciate if any one can give any input . The problem is i need to assign each authorisation the existing user having manually to the new user.
regards
Tony

Thanks for the mail.
I check the "Reference User for Additional Rights" -- there is no refernce user assgined.
I checked the table USR04 the no. of Profle for the two users are diffrent and in the table UST04 also the the existing uer is having addtional profiles.
I like to add one more point Some of the roles of the  two users are composite roles and both the composite and its orignial roles are included the profile of both users.
Does any one have idea of the authorisations starting with T_PXXXXXXXX

tony
