Hello Shankar,
thank you for the reply, I agree with you, but what would be the solution in this case? If it's normal behaviour, how could I extend the URL of the page with '?sap-config-mode=x' to reach customizing mode?
I've tried to open the required page from pfcg, and extend the URL there. In that case, I can open the required page, then I extend the URL (?sap-config-mode=x), and I can reach customizing mode. HOWEVER in this case the application configuration doesn't get loaded.
So, finally, I have the correct application this time, just without configuration now (and that's why all the rest of the page becomes blank).
Do you have any suggestions?
Thanks,
Tam
