How do i stop a Do Varrying Loop if no condition met?

[Wil_Wilstroth]

Hi all,

what is the best method to stop a loop in a DO VARYING from continuous looping (and getting an error dump)?

thanks

Hi,

You should put a condition which would be satisfied atleast once. Else you can set a flag.

DESCRIBE TABLE ITAB LINES l_lines.

DO VARYING ITAB-SRNO NEXT ITAB-PRNO.

IF ITAB-SRNO = '10'.

EXIT.

ENDIF.

<b>IF sy-tabix = l_lines.

EXIT.

ENDIF.</b>

ENDDO.

i.e. First get the total number of records in the internal table. If the processsing inside DO has already processed the total number of records, then EXIT.

pease give more details, if you post your code people will be able to come up with better examples.......

what sort of dump are you getting?

For example,

Data : begin of t_dat occurs 0,

owner(020) type c,

property01(020) type c,

property02(020) type c,

property03(020) type c,

property04(020) type c,

end of t_dat.

Data : g_pro like t_dat-property01.

t_dat-owner = 'James Bond'.

t_dat-property01 = 'Bungalow'.

t_dat-property02 = 'Double Storey'.

Append t_dat.

Loop at t_dat.

do varying g_pro from t_dat-property01

next t_dat-property02.

if g_pro = 'Bungalow'.

write : / t_dat-owner, ' owns a ', g_pro.

exit.

endif.

enddo.

endloop.

So, if lets say the owner doesn't own any properties. Now when the do varying loops, how do i make it stop from causing error dump?

Thanks

OK, in this case I'd code it like this:

do <b>4 times</b> varying g_pro from t_dat-property01

next t_dat-property02.

Then it will only try to operate on the 4 property fields.

try this...

Loop at t_dat.
do varying g_pro from t_dat-property01 
next t_dat-property02.
if g_pro = 'Bungalow'.
write : / t_dat-owner, ' owns a ', g_pro.
exit.
<b>else if  g_pro is initial.
exit.</b>
endif.
enddo.
endloop.

Hi,

Data : begin of t_dat occurs 0,

owner(020) type c,

property01(020) type c,

property02(020) type c,

property03(020) type c,

property04(020) type c,

end of t_dat.

Data : g_pro like t_dat-property01.

t_dat-owner = 'James Bond'.

t_dat-property01 = 'Bungalow'.

t_dat-property02 = 'Double Storey'.

Append t_dat.

Loop at t_dat.

<b>if t_dat-property01 eq 'Bungalow'.

write : / t_dat-owner, ' owns a ', t_dat-property01.

exit.

elseif t_dat-property02 eq 'Bungalow'.

write : / t_dat-owner, ' owns a ', t_dat-property02.

exit.

elseif t_dat-property03 eq 'Bungalow'.

write : / t_dat-owner, ' owns a ', t_dat-property03.

exit.

elseif t_dat-property04 eq 'Bungalow'.

write : / t_dat-owner, ' owns a ', t_dat-property04.

exit.

endif.</b>

enddo.

endloop.
