Changing Logon Screen WebAS ABAP: image for header
we would like to change the default logon screen of a WebAS ABAP 7.0 service (CLPBID - APO Collaborative Transportation Planning). The problem is the image for the header (SICF, service, tab error pages, tab logon erros, configuration, adjust links an images).
When we enter - for testing purposes - the URL "/SAP/PUBLIC/BC/Webicons/w_approv.gif", the GIF is displayed correctly. When we choose the URL "/SAP/PUBLIC/BC/Icons/s_aanode.GIF", the GIF is missing. We also created a new folder (SE80, MIME repository), e.g. "/SAP/PUBLIC/TEST" with a file test.gif. But this file is also not displayed on the logon page.
What is the difference between those folders. Are there any prerequsites for using other folders in the URL field? Security concerns? For claritys sake, we would like to create new folders with our own ressources...
Thank you very much
