Hi,

You can all these fields in table 'SYST'. these fields holds the values at runtime and can be accessed anywhere in the program without any delcaratio.

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 are those variables that are filled by the sap system itself during the process flow. these are the common system fields,

sy-lsind -> index of the list created during the current event

sy-listi -> index of the list from which the event was trigerred

sy-lili -> absolute number of the line from which the event is triggered

sy-lisel -> content of the line selected

sy-curow -> position of the line in the window from which the event was triggered.

sy-cucol -> position ofthe column in the window from which the event is triggered.

sy-cpage -> page number of the first displayed page of the list from which the event is triggered.

sy-staro -> number of the first line of the fist page of the list from which the event is triggered.

sy-staco -> number of the first column displayed in the list from which the event is triggered.
