Hi,

I have a program where iam appending data in to the internal table .

DATA : BEGIN OF ITAB OCCURS 10,

A TYPE I,

B TYPE I,

END OF ITAB.

DO 5 TIMES.

ITAB-A = SY-INDEX.

ITAB-B = SY-INDEX * 10.

APPEND ITAB. * COMMENTS FROM HEADER LINE ARE APPENDED TO THE BODY

ENDDO.

WRITE : / ITAB-A,ITAB-B. OUTPUT TILL HERE IS 5 50 ( WHERE SY-INDEX = 5)

SKIP.

LOOP AT ITAB[] INTO ITAB.

WRITE : / ITAB-A,ITAB-B.

ENDLOOP.

My question is what happen to the values of , and how?

SY-INDEX

SY-TABIX

SY-FILL.

With regards

Bhavana

HI,

SY-INDEX will be incremented within a DO-END or WHILE-ENDWHILE.

SY-TABIX will be incremented whenever an internal table is looped upon using LOOP statement.

Also when any particular row of an internal table is read successfully using READ statement; then SY-TABIX will hold the row number.

When you use SY-INDEX in DO loop it increses as follows

Do Loop - Sy-index will increse by 1 in each loop.

LOOP AT ITAB. - SY_TABIX will increase by 1 in each loop.

So use SY-INDEX in DO LOOP and SY-TABIX IN looping internal table.

Hi,

After the execution of loop used for printing the lines of internal table values of SY-TABIX will change while that of SY-TFILL and SY-INDEX will remain same as before.

Hi

it would display the values from 1-10 ,2-20,........

SY-TABIX : used for record count of internal tables.

SY-INDEX : used for loop counter.

SY-TFILL contains the number of lines in the relevant internal table.
