default_host/sap/public/bsp/sap no authorization

Hi everyone,

I am trying to follow document How To Customize BW Web Logon Screens and Functions.

It refers to right clicking on default_host/sap/public/bsp/sap and clicking on new sub-element but when I do this I get the error message 'No authorization to change/delete virtual host/system service'.

The SU53 shows all authorisations successful and doing an authorisations trace does not show any errors.

Can anyone offer any assistance?

Gary
