You are not authorized to make change & Use at least SAPGUI 7.30 ! You will now be logged off ...

Hi Everybody;

I have a problem for SAP GUİ.

First one i have tried logon via I62 and i logged on. If i wanted create a ABAP program, SAP GUI gave me "you are not authorized to make changes" error.

I used client 800.

Second one i have tried logon via E66. But i can not logon. If i am writing my useranme and password, SAP GUI said me; "Use at least SAPGUI 7.30 ! You will now be logged off ..."

How can i use to SAP GUI? How can i learn SAP GUI?

Who can help me?

(I am sorry for my English. Because i can not speak so good English.)

Best Regards
