The SAP logon icon is one of the items found in the start menu of your desktop. You or the system administrator can also set up a shortcut icon on your desktop to facilitate the log on process. Logging on to an SAP system requires input in various fields.
The SAP log on screen includes the following elements:
Client:
- SAP systems are client systems.
- The client concept enables the parallel operation, in one system, of several enterprises that are independent of each other in business terms.
- A client is, in organizational terms, an independent unit in the system.
- Each client has its own data environment and therefore its own master data, transaction data, and assigned user master records.
User:
- To log on to the system, a master record must exist in the system for that user.
- The master record must refer to the relevant client.
- The assigned user ID is unique to the specific individual.
Password:
- To protect access, a password is required to log on.
- Each user creates their own personal password.
- The password is hidden with a field of asterisks.
Language:
- The language field is an optional entry.
- If left blank, the system loads with the default system language.
For security and licensing reasons, multiple logons are logged in the system. A warning message appears if the same user attempts to log on more than once.
General Screen Layout

The system administrator can include an image, for example your company logo, on the right-hand side of the screen. This image can only be entered system-wide and is a cross-client setting. Individual users can personalize their user interface and prevent this image being called by switching it off. From the main menu bar, choose Extras→Settings→Do Not Display Picture.
