List of System Fields in ABAP
These are the list of some the important System fields in ABAP and its details.
| System Fields | Type | System Field details |
| sy-abcde | c(26) | This Transaction code Contains the Latin alphabet. Can be used to access individual letters directly by specifying the offset/length, regardless of the code page. |
| sy-batch | c(1) | This Transaction code Set to “X” in an ABAP program that runs in the background, otherwise initial. |
| sy-binpt | c(1) | This Transaction code Set to “X” during processing of batch input sessions, and in ABAP programs called using CALL TRANSACTION USING. Otherwise initial. |
| sy-calld | c(1) | This Transaction code Contains a blank character in the first program in a call sequence, otherwise contains the value “X”.

In non- Unicode systems, this position also corresponds to the column in the displayed list. In Unicode systems, this is only guaranteed for the lower and upper output limits applicable to each output, as one character may take up more columns in the list than positions in the list buffer. |

| sy-cucol | i | This Transaction code return Horizontal cursor position in the display on a dynpro. Counting begins at column 2. |
| sy-curow | i | This Transaction code return Vertical cursor position on the screen display of a screen. Counting begins at line 1. |
| sy-datar | c(1) | At PAI, contains “X” if at least one input field of a screen has been changed by a user or by further data transfer, otherwise initial. |
