In PC-UI for opportunities application when I try to save the opportunity it gives the following error:
500 SAP Internal Server Error
Error message: S:ZMSG:000 Authorization Check Error ( type of termination: ERROR_MESSAGE_STATE )
I am not able to understand what kind of authorization it is asking for because the user through which I login has full authorization.
Pls suggest some solution to this problem.
This seems like a custom error message to me(ZMSG:000). You can try checking in SE93, message class is ZMSG, choose radio button "Messages" and press "Display". This will take you to the message, here choose number "000" and press "Where-Used" button (CtrlShiftF3), that will take you to the code that is causing this error.
Alternatively, use Txn SU53 to check last failed authorization check.
It seems like your code is checking for a custom authorization object which is not included in your profile.
