Exiting a loop

Former Member — Mon, 19 Jan 2009 06:21:16 GMT

This is my code

loop at itab. ---> loop 1

read table itab2 with key id = itab-id.

if sy-subrc = 4.

exit.

endloop.

Loop at itab3 -

>loop 2

endloop

Now I want that when whenever sy-subrc = 4 in loop 1... the exit should exit the whole block ie loop 2 also...But with my above code it is exiting only the first loop but passing thorught loop 2.

How should I solve my purpose...( Using continue is not helping either)

data : l_flag type c.

loop at itab. ---> loop 1
read table itab2 with key id = itab-id.
if sy-subrc = 4.
l_flag = 'X'.
exit.
endloop.

if l_flag is initial.
Loop at itab3 ---->loop 2
{ exp

}
endloop.
endif.
clear l_flag.

Hi Priya,

Try this way.

data: flag type c.

loop at itab. ---> loop 1

read table itab2 with key id = itab-id.

if sy-subrc = 4.

flag = 'X'.

exit.

endloop.

Loop at itab3 -

>loop 2

{ IF flag = 'X'.

exit.

ENDIF.

}

endloop

Hi,

then, you can check the subrc while doing the second loop.

eg:

loop at itab. ---> loop 1

read table itab2 with key id = itab-id.

if sy-subrc = 4.

exit.

endloop.

IF sy-subrc EQ 0.

Loop at itab3 -

>loop 2

endloop

endif.

Hope it helps!!

If ITAB3 is having relationship with either ITAB1 or ITAB2 then

loop at itab. ---> loop 1

read table itab2 with key id = itab-id.

if sy-subrc = 4.

exit.

else.

read table itab3 with key id = itab-id. or read table itab3 with key id = itab2-id.

if sy-subrc = 0.

*Exp

endif.

endloop.

The above code will improve the performance.

Pavan - SY-SUBRC will depend on whether or not there are entries in itab, not the READ TABLE itab2 statement.
