Hi
The issue facing with "basis" is as well as with other ids, the id used for tracing is "basis" only.
User-ID : basis having "SAP_ALL and SAP_NEW" authorization and all relevant authorization.
Trasing analysis of USER-ID : basis in ST01 every thing showing fine, in SU53 also it showing fine.
Before also we implemented 4 transaction launcher also those working fine.
But current for the Z Tcode: ZMSITE it shwoing error.
The same t code if am executing in SAPGUI level its working fine but through CRM web-ui it showing the error messgae "you dont have authorization". in web ui the ztcode mapped by using transaction launcher.
Please suggest where we are going on.
Thanks Andrea, for your concern 
Vimita
