Prerequisites
Before you log on, you should have the following information to hand:
- You must know the name of the system you are logging on to. Usually, the administrator would have already created a favorite for this system, depending on whether SAP GUI or a Web link is used to access the logon window.
- You need your client number, your user ID, and your password.
When you log on for the first time, you usually need an initial password for the system. You can get this password from your system administrator.
- Decide which language you want to use for the logon.
For more information, contact your system administrator.
Procedure
- If you are working with a locally installed SAP GUI for Windows or SAP GUI for Java, you first open the SAP Logon program, and select the required system from the favorites list.
- If you want to access the system from a browser, use the link provided.
The logon screen will then be displayed.
- To log on to an SAP system, enter your client number in the Client field.
If a default client number appears in the field, you can either accept it, or change it by entering a new one.
- In the User field, enter your user ID.
- Enter your Password:
When you log on for the first time, use the initial password assigned by your system administrator. Directly after your first logon, you are asked to replace the initial password with a personal password. When you choose your password, follow the security polices of your company regarding the length and format of passwords. When you log on next time, you use your personal password.
- If you want to change the display language, you enter or select a different language key, and press the enter key.
If you have to change your password, the change is confirmed and the copyright popup appears.
- Choose Next.
If there are system-wide messages, the System Messages dialog box appears. After you have read the messages, choose Continue to close the dialog box.
Logging Off
To log off, choose 
System
Log Off
from the menu bar.
The dialog box Log Off appears.
If you are not certain that you have saved all of your data and you do not want to log off, choose No to return to the screen in which you were working. Otherwise choose Yes.
All your SAP system sessions will be closed. You have successfully logged off.
