SY-BATCH
X if the ABAP program is running in the background, otherwise space
Batch Input
SY-BINPT
X while a batch input session is running and when an ABAP program is called using
CALL TRANSACTION USING, otherwise space.
OPTIONS FROM in the CALL TRANSACTION USING statement can set SY-BINPT to space either for
the entire duration of the program, or at the end of the BDC data.
SY-BINPT is always space during a CATT procedure
SY-TABIX
Current line of an internal table. SY-TABIX is set by the statements below, but only for index tables. The field is either not set or is set to 0 for hashed tables.
APPEND sets SY-TABIX to the index of the last line of the table, that is, it contains the overall number of entries in the table.
COLLECT sets SY-TABIX to the index of the existing or inserted line in the table. If the table has the type HASHED TABLE, SY-TABIX is set to 0.
LOOP AT sets SY-TABIX to the index of the current line at the beginning of each loop lass. At the end of the loop, SY-TABIX is reset to the value that it had before entering the loop. It is set to 0 if the table has the type HASHED TABLE.
READ TABLE sets SY-TABIX to the index of the table line read. If you use a binary search, and the system does not find a line, SY-TABIX contains the total number of lines, or one more than the total number of lines. SY-INDEX is undefined if a linear search fails to return an entry.
SEARCH <itab> FOR sets SY-TABIX to the index of the table line in which the search string is found.
SY-TFILL
After the statements DESCRIBE TABLE, LOOP AT, and READ TABLE, SY-TFILL contains the number of lines in the relevant internal table.
SY-TLENG
After the statements DESCRIBE TABLE, LOOP AT, and READ TABLE, SY-TLENG contains the length of the lines in the relevant internal table.
SY-TOCCU
After the statements DESCRIBE TABLE, LOOP AT, and READ TABLE, SY-TLENG contains the initial amount of memory allocated to the relevant internal table.
The following system fields are always set automatically.
The GET TIME statement synchronizes the time on the application server with the time on the database server and writes it to the field SY-UZEIT. SY-DATUM and the system fields for the local timezone (SY-TIMLO, SY-DATLO, and SY-ZONLO) are also reset.
