0 LIST OF SYSTEM FIELDS IN ABAP

LIST OF SYSTEM FIELDS IN ABAP:

The ABAP system fields are active in all ABAP programs. They are filled by the runtime environment, and you can query their values in a program to find out particular states of the system. Although they are variables, you should not assign your own values to them, since this may overwrite information that is important for the normal running of the program. However, there are some isolated cases in which you may need to overwrite a system variable. For example, by assigning a new value to the field SY-LSIND, you can control navigation within details lists.

The names and data types of the system fields are contained in the ABAP Dictionary structure SYST. To address them in an ABAP program, use the form SY-<fieldname>. Within screen flow logic, you can also use the form SYST-<fieldname>.

·         System fields for SCREENS.

System fields are set at the PAI (Process After Input) event for every screen.
These can be also used for interactive list processing, except for SY-DATAR, SY-LOOPC, and SY-STEPL.

SY-CUCOL
Horizontal cursor position Counting starts at column 2

SY-CUROW
Vertical cursor position Counting starts at row 1

SY-DATAR
Set to X at time of PAI if at least one screen input field was changed by the user or other data transfer, otherwise empty.

SY-LOOPC
Number of rows currently displayed in a screen table (table control).

SY-SCOLS
Number of columns in current screen.

SY-SROWS
Number of rows in current screen.

SY-STEPL
Index of current row in a screen table (table control). Is set at every loop pass. Outside a loop, for example during the POV(Process On Value Request) event for a table row, SY-STEPL is not set appropriately.

SY-TITLE
Text that appears in the title bar of the screen. For selection screens and lists this is the program name, otherwise SAP R/3. Can be set during PBO (Process Before Output) using SET TITLEBAR.

SY-UCOMM
Function code that triggered the event PAI. Every user action that triggers PAI is assigned a unique function code, with one exception: Choosing Enter triggers PAI and different function codes can be transferred to SY-UCOMM:
• If there is an entry in the command field of the standard toolbar, this is transferred to SY-UCOMM as the function code.
• If there is no entry in the command field and a function code is assigned to the ENTER key, this function code is transferred to SY-UCOMM.
• If the command field does not contain an entry and no function code is assigned to the ENTER key, it is empty and the content of SY-UCOMM is not affected.

Selection Screens

SY-SLSET
Variant used to fill the selection screen.

System Fields for Date and Time.

The following system fields are always set automatically. If necessary, the GET TIME statement synchronizes the application server time with that of the database server and writes it to the system field SY-UZEIT. SY-DATUM and the system fields for the local time zone, that is SY-TIMLO, SY-DATLO, and SY-ZONLO are also reset.
SY-DATLO
Local date of user, for example 19981129, 19990628.
SY-DATUM
Current (application server) date, for example 19981130, 19990627.
SY-DAYST
During daylight saving time X, otherwise empty.
SY-FDAYW
Factory calendar weekday, Sunday 0 ... Saturday 6.
SY-TIMLO
Local time of user, for example 154353, 225312.
SY-TZONE
Time difference to Greenwich Mean Time (UTC) in seconds, for example 3600, 10800.
SY-UZEIT
Current (application server) time, for example 164353, 215312.
SY-ZONLO
Time zone of user, for example CET, UTC.
