DO w_week TIMES.

IF so_date-low IS NOT INITIAL.

CLEAR: wa_weektable, w_week.

CALL FUNCTION 'GET_WEEK_INFO_BASED_ON_DATE'

EXPORTING

date = so_date-low

IMPORTING

week = wa_weektable-week

monday = wa_weektable-monday

sunday = wa_weektable-sunday.

wa_weektable-wday = so_date-low.

APPEND wa_weektable TO it_weektable.

CLEAR wa_weektable.

so_date-low = so_date-low + 1.

ENDIF.

ENDDO.

HI,

initially the value of w_week is 3 so the do...enddo will be processed for 3 times. after this looping number of times is assigned u r changing the value of that variable.

rgds,

the "CLEAR w_week" is just a bug that can be removed.

When first reaching the DO loop, the system will evaluate the contents of w_week once. Subsequent changes will have no effect.

Cheers

Hello.

If that DO/ENDDO block is not in a form which is called more times in runtime, it makes no sense that CLEAR statement. I don't know the program logic.

Inside tha that DO, clearing w_week will affect nothing. However, will prevent next time to enter inside it again (if the is one). If you want to end the block you should use statement EXIT.

Best regards.
