SAP Logon is a Windows PC program that acts as an interface between the R/3 system and the common SAP user interface, SAPGUI. SAP Logon Screen shows a list that contains SAP application servers, etc. A specific IP address is associated with each server on the list. There are 4 application servers used for SAP Engagement Readiness.
The R/3 System is a client system . The client concept enables the joint operation, in one system, of several enterprises that are independent of each other in business terms. During each user session, you can access only the data of the client selected during the logon. A client is, in organizational terms, an independent unit in the R/3 System. Each client has its own data environment and therefore its own master data and transaction data, assigned user master records and charts of accounts, and specific customizing parameters. A user master record linked to the relevant client must be created for users to be able to log on to the system. To protect access, a password is required for logon. The password is hidden as you type (you only see asterisks). SAP systems are available in several languages. Use the Language input field to select the logon language for each session. Multiple logons are always logged in the system beginning with Release 4.6. This is for security as well as licensing reasons. A warning message appears if the same user attempts to log on twice or more. This message offers three options: Continue with current logon and end any other logons in the system Continue with current logon without ending any other logons in the system (logged in system) Terminate current logon
The Menu Bar contains the Office, Logistics, Accounting, Human Resources, Information Systems, Tools, System, and Help Options that perform general functions. The Application Toolbar activates important functions directly. The Log Off pushbutton allows a user to log off. Any unsaved data will be lost. The Help pushbutton in the Standard Toolbar navigates to the specified help. This can also be activated by pressing the F1 function key. The Local Information pushbutton displays options for customizing the local layout such as the window layout, color, and font. The Command Bar allows the user to type in a transaction code to get to a specific screen. Each function is assigned an SAP transaction code. The Status Bar is where error, warning and informational messages are displayed.
SAP Easy Access is the standard entry screen displayed after logon. Using the menu path Extras Set start transaction , you can select a transaction of your choice to be the default entry screen after logon. You navigate through the system using a compact tree structure that you can adapt to your own specific requirements. Use the menu path Extras Settings to change your view of the tree structure. You can use this to display technical names (transaction codes). You can also create a Favorites list of the transactions, reports, files and Web sites you use most. You can add items to your favorites list using the Favorites menu option or by simply dragging and dropping them with the mouse.
Transaction codes are stored in table STC. The transaction code of a particular screen can be easily identified by accessing the System menu and choosing the “Status” option. The transaction code will be displayed in the Sap Data/Repository Data/Transaction field.
When logging on to a system with more than one user ID, or onto multiple clients on the same system (for example, some servers have one client for coding and another client for testing), be sure not to confuse the different sessions!
The system menu can be accessed from all R/3 transactions. The System Services menu contains, among others, the following options: Reporting: starts reports (ABAP programs) Output controller: lets you manage user-specific print requests Table maintenance: allows you to process tables and views Batch input: administers batch input sessions and data transfer Jobs: lets you can administer jobs that are processed in the background SAP Service: enables you to log on to SAP’s SAPNet R/3 Frontend
Users can get object-specific information (for example, about fields, new options, messages, etc.) anywhere in the system by positioning the cursor on the relevant object and pressing F1. Search helps are ABAP dictionary objects designed to provide the users with a mechanism to search for and then select the appropriate field values. Search helps are used to define input help (F4 help) for screen fields. Search fields are fields whose possible input values are sought in the possible entries (F4 help) process.
The Help system should be the first place to look with an ABAP question. In addition, the help provides good explanations of each SAP module if a functional query should arise during programming. NOTE: If SAP is unable to locate the help files, edit C:WINDOWSSAPDOCCD.INI to point to the network drive or the CD drive where the documentation is located.
