Hello VKUMAR A,
Another option:
Because yours is selective authorization check, I feel this can be achieved through user-exit CPAU0001 (Enhancement for Authorization Check in Task Lists). Here Function exit EXIT_SAPLCPAU_001 responds to tcode CA02. You can put your code here in the include ZXCPAU01. For your ABAPer it will be a small job. (Because you mentioned that it is for certain users, this list of users can be handled through a small z-table.)
