Change Stylesheets of SAP E-Recruiting 600
probably this is a dumb question, but I did not find any straight forward solution yet: We want to change the stylesheets of SAP E-Recruiting 600 (i.e. fonts, colour schema, table layout). Our E-Recruiting system is a stand alone system and not integrated in any SAP Enterprise Portal, therefore we have to change the stylesheets on the WebAS, where E-Recruiting is running. I found quite a lot information on how to replace single MIMEs from the SAP standard theme (sap_tradeshow), but I have not found any straight forward procedure to change the whole theme. So my questions are:
Is it possible to assign a different theme to the complete E-Recruiting application at once (a SAP Enterprise Portal is not avaliable)?
How can the theme be edited w/o changing every single css-file by hand (a SAP Enterprise Portal is not avaliable)?
Any help is highly appreciated.
