    Hello Raj,
    i recently registred here and fixed so many issues with the help of articles you posted.
    I forgot GUI login password, can you please help me out.

    Best of regards,


    • Raj


      What is the user name you are using to login? Did you remember the user name and password given at the time of installation for sap* and ddic. If you remember you can login as either of these users and reset the password of your existing user which you are using to work with. Also inform me the client which you are using. I will try to help you to solve the problem.
