no authorization for query/Web application assigment in roles

Hi All,

in order to clean/reorganize our roles, I have to clean some query/Web application/Workbook assignment in roles. After I have loged in into BEX Browser I have cleaned/moved some objects from roles. But it seem that I have not all necessary rights to do that.

Which is the relevant authorization object which I need to change query assignemnt in roles?

Is there an other way to add/remove queries/Web applications from roles?

Any help would be great. Thanks in advance.

Best regards,

Stefanos from Munich/germany.
