How to exit a loop

Former Member — Fri, 02 May 2008 09:56:42 GMT

How to exit from a loop. for eg

C = sy-tabix.

LOOP AT IT_GRAPH1.

D = SY-TABIX.

IF D GT C.

EXIT.

ENDIF.

<cond>

I want that when D becomes greater then C then it should exit the whole loop processing.

But this code is not working even if D becomes greater then C still the loop processing continue.

Please Help.

Hi,

Check the below logic.

data: c like sy-tabix, d like c.

data: begin of itab occurs 0,

num type i,

end of itab.

do 5 times.

itab-num = sy-index.

append itab.

enddo.

C = 2 ."sy-tabix.

LOOP AT ITAB.

D = SY-TABIX.

IF D GT C.

EXIT.

ENDIF.

write:/ itab-num.

ENDLOOP.

C = sy-tabix.

LOOP AT IT_GRAPH1.

D = SY-TABIX.

IF D GT C.

EXIT.

ENDIF.

IF IT_GRAPH1-type = 'DO'.

M = M + 1.

ELSEIF IT_GRAPH1-type = 'ENDDO'.

N = N + 1.

ELSEIF IT_GRAPH1-type = 'LOOP'.

L = L + 1.

ELSEIF IT_GRAPH1-type = 'ENDLOOP'.

E = E + 1.

ELSEIF IT_GRAPH1-type = 'IF'.

I = I + 1.

ELSEIF IT_GRAPH1-type = 'ENDIF'.

P = P + 1.

ELSEIF IT_GRAPH1-type = 'CASE'.

R = R + 1.

ELSEIF IT_GRAPH1-type = 'ENDCASE'.

S = S + 1.

ENDIF.

ENDLOOP.

HII THIS IS MY CODE....the given logic is not working here

I can't see anything wrong with that code. 'EXIT' will exit a loop. Are you looping within a loop so that C is reset each time? It is worth break-pointing and checking what happens and what values are being set.

Firstly Do not Use the variable names as C or D , N as they are the types of declaration in ABAP as well ,

Change the names and try your Code ,, Logically should work .

Or else .

Instead of

IF D GT C.

EXIT.

ENDIF.

use ,

While D_temp LT C_temp .

IF IT_GRAPH1-type = 'DO'.

M = M + 1.

ELSEIF IT_GRAPH1-type = 'ENDDO'.

N = N + 1.

ELSEIF IT_GRAPH1-type = 'LOOP'.

L = L + 1.

ELSEIF IT_GRAPH1-type = 'ENDLOOP'.

E = E + 1.

ELSEIF IT_GRAPH1-type = 'IF'.

I = I + 1.

ELSEIF IT_GRAPH1-type = 'ENDIF'.

P = P + 1.

ELSEIF IT_GRAPH1-type = 'CASE'.

R = R + 1.

ELSEIF IT_GRAPH1-type = 'ENDCASE'.

S = S + 1.

ENDIF.

ENDWHILE .

hi,

try this code


C = sy-tabix.
LOOP AT IT_GRAPH1 TO C.
 <processing goes here>
ENDLOOP.

or this one


C = sy-tabix.
LOOP AT IT_GRAPH1.
  D = SY-TABIX.
  IF D GT C.
    EXIT FROM STEP-LOOP.
  ENDIF.
ENDLOOP.

regards,

Peter

Hi Priya,

at first glance your code should work. The only thing I can think of is something in the typing of variables C and D that make the comparison not work.

Can you give us your definition of C and D?
