before you log on the  first time,your system administratorwill give you an initial password. During the logon process,you should create a new password, one that you alone will know. After that,use your own password whenever you log on.

The SAP logon icon now appears in both the ask bar(together with the SAP release number) and the system tray (that is,the bottom right corner of your dekstop).

If there are system-wide messages,the system Messages dialog box appears. After you have read the messages, choose continue or enter to close the dialog box.

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 bussiness terms.

A Clientis, 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.

For a user to log on to the system, a master record must exist in the system for that user,reffering to the relevant client. To protect access, a password is required for logon. The password entry is masked "with asterisk".

Multiple logons are always logged in the system. This is for security as well as licensing reasons . A warning messages appears if the same user attempts to log on more than once. The messages offers three options:

·         Continue with the current logon and end any other session (s) of the same user in the system

·         Continue with the logon without ending other sessions in the system (logged in the system)

·         Terminate current logon attempt

Navigation Tree

In SAP Easy Access, you can create a favorites list containing:

·         Transaction

·         Files

·         Web addresses

Every function (not screen ) in the SAP system is a transaction code (T Code). You can access the assigned transaction code from any screen  in the system. You can find the transaction code for the functions you are working in at the moment by choosing System information on the status bar or by choosing status under the system menu option. Other possible entries:

·         /n – ends the current transaction

·         /o – opens a new session

·         /i – ends the current session

·         /oXXX – where XXXX is a transaction code takes you to the specified transaction code suchas/opa30 will open a new session at the transaction code pa30  - Maintain Master Data.

Status Bar

The status bar provides general information on the SAP system and transaction or task you are working on. System messages display left of the status bar. The right end of the status bar contains three fields: one with server information,the other two with status information.

·         Left end of status bar: Error and other system messages display here.

·         Right end of the status bar :System information displays here. Choose this field to display the following system information:

-          System

-          Client

-          User

-          Program

-          Transaction

-          Response time

·           Second status field: this field tells you what server you are connected to.

·           Third status field: This field displays the data entry mode. Choose this field to switch between Insert (INS) and Overwrite(OVR) modes.

Multiple Sessions

You can create a session at any time. You do not lose any data in sessions that are already open.

You can create up to six sessions per logon. Each session you create is as if you logged on to the system again. Each session is independent  of the others. For example, closing the first session does not cause the other sessions to close.

Too many open sessions can results in slower system performance. For this reason, youe system administrator may limit the number of sessions you can create to fewer than six.

As long as you remain logged on to the SAP system,you can leave a session for as long as you like. Moving to a different session is like putting a telephone call o hold: you can resume the call whenever you are ready. You can move among sessions as often as you like without losing any data.

To move from one session to another, click any part of the window that contains the sessions you want to go to (or use the keys specified for changing windows). The window you choose becomes the active window:it movies in front of all the other windows on your screen.

If you have several sessions open,you can minimize the sessions you are not using. When you need to use one of these sessions later,you can restore it by clicking the appropriate symbol in the status bar,making it the active session. By minimizing the sessions you are not using,you can significantly reduce the system load.

After finish using a session, it is a good ides to end it. Each session uses system resources that can affect how fast the SAP system responds to your requests. Before you end a session, save any data you want to keep. When ypu end a session, the system does not prompt you to save your data.
