abap - go back to loop iteration

Former Member — Sat, 09 Aug 2008 10:10:31 GMT

i have developed a report in that there is a loop and inside loop there are many read statements and messages.

my querry is, whenever any message pop up i.e. when that condition fails, the loop should go to next iteration i.e. if the condition has failed in 2nd sy-tabix then immediately the loop should start and it should start from 3rd iteration.

tabix = 0.

loop at itab.

read statement

message

what should i write here stop or exit or var = x

read statement

message

what should i write here stop or exit or var = x

read statement

endloop.

from message it should go to next iteration of the loop.

thanx in adv

actually these messages are inside perform statements, so inside perform there is no loop and therefore 'continue' will not work there.

If it is inside perform then you can use EXIT and a flag.

loop at itab.

perform check_something.
if v_flag = 'X'.
 continue.
endif.

endloop.

form check_something.
clear v_flag.

read ....
read....
message.
v_flag = 'X'.
exit.

endform.
