Hi Guru's,

Pleae can anybody expalins me what is the difference between sy-tabix and sy-index(Loop Index) ?

because in one case i am Modifyimg the internal table inside the do loop by giving sy-index ((Index of Internal Tables)(MODIFY scarr_tab INDEX sy-index FROM scarr_wa

TRANSPORTING currcode. ) in the syntax

and in other case inside loop statement i am modifyng same record by giving sy-tabix MODIFY scarr_tab INDEX sy-tabix FROM scarr_wa

TRANSPORTING currcode.) in the syntax.

in both case its working fine but i am not getting which one i have to use where to modify the internal table?

Hi,

generaly in DO loops we use sy-index and when we LOOP the internal tables then we use sy-tabix..

check the below link also

sy-index maintain index of DO loop.

Hi Priya,

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

Sy-index Contains the number of loop passes in DO and WHILE loops, including the current loop pass.

that is if 1 st time loop processing it is 1 if second time it is 2 etc...

Plz reward if help,

Mahi.
