Hi Swapna,

SY-INDEX

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

Internal Tables

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

SY-TFILL:

With the statements DESCRIBE TABLE, LOOP AT, and READ TABLE, SY-TFILL is filled with the row number of the addressed internal table

Hi Swapna,

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 below 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.

also go through below thread...

Hope it will solve your problem..

Reward points if useful..

Thanks & Regards
