Hi,

SY-TABIX means Table Index. This signifies the number of table index. Each row of a table has certain index or counter. The value of sy-tabix for the last entry would be equivalent to number of table entries.

SY-INDEX means the number of Iterations for a loop. bascially DO - ENDO .

SY-INDEX is not equal to SY-TABIX.

Check the belwo program

report tabix_index.

DO 100 times.

wa_tab-index = sy-index.

append wa_tab to itab.

clear wa_tab.

enddo.

loop at itab into wa_tab.

write:/1 sy-tabix.

endloop.

I hope this answers your question.

Reward all helpful answers,

Regards,

Omakr.

hi,

sy-index will give u the number of iteration in the loop.

sy-tabix will give u the number rows filled in an internal table at the moment.

SY-TABIX:

Current line in an internal table. With the following statements SY-TABIX is set for index tables. With hashed tables, SY-TABIX is not filled or it is set to 0.

- APPEND sets SY-TABIX to the index of the last table row, that is the total number of entries in the target table.

- COLLECT sets SY-TABIX to the index of the existing or appended table row. With hashed tables, SY-TABIX is set to 0.

- LOOP AT sets SY-TABIX to the index of the current table row at the beginning of every loop pass. After leaving a loop, SY-TABIX is set to the value it had before entering the loop. With hashed tables, SY-TABIX is set to 0.

- READ TABLE sets SY-TABIX to the index of the table row read. If no row is found with binary search while reading, SY-TABIX contains the index of the next-highest row or the total number of rows +1. If no row is found with linear search while reading, SY-TABIX is undefined.

- SEARCH itab FOR sets SY-TABIX to the index of the table row, in which the search string was found.

SY-INDEX:

SY-INDEX contains the number of loop passes in DO and WHILE loops, including the current loop pass.

Hi,

if you are using a internal table within loop, then sy-tabix wil return the current record number of the internal table.

sy-index wil return the current loop index.

Hi,

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_INDEX - In a DO or WHILE loop, SY-INDEX contains the number of loop passes including the current pass.

Hope it was useful.

Thanks,

Sandeep.

SY-INDEX

In a DO or WHILE loop, SY-INDEX contains the number of loop passes including the current pass.

-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.
