DO ENDO Logic

[Former Member]

Hi ABAPers,

Neep Help.

REFRESH: i_zxxx.
  n = 1.
  DO n TIMES.
  SELECT *
         FROM zxxx
         INTO TABLE i_zxxx
         WHERE werks in s_site
         AND datum eq s_date-low
         AND status eq 'C'.
  IF i_zxxx is INITIAL.
  n = 1.
  s_date-low = s_date-low - 1.
  ENDIF.
  ENDDO.

In the above code I am expexting the do endo loop to run again when i_zxxx is intial by setting n = 1.

kindly help me change the logic to obtain the same.

Hi,

this is a single loop because n = 1 at start of the do ... enddo loop.

For your needs you should use a DO without n times and leave it, when sy-subrc eq 0 or date has a special value with EXIT.

Hi ,

use this:

REFRESH: i_zxxx.

n = '1'.

while n = '1'.

SELECT *

FROM zxxx

INTO TABLE i_zxxx

WHERE werks in s_site

AND datum eq s_date-low

AND status eq 'C'.

IF i_zxxx is INITIAL.

n = 1.

s_date-low = s_date-low - 1.

else .

clear n.

ENDIF.

ENDWHILE.
