Here, you get in itab all the days from begin to end, there's also a day parameter to choose wich day to count (1= monday,... 7=sunday).

PARAMETERS: begin TYPE sy-datum,
            end   TYPE sy-datum,
            day   TYPE c.

DATA: l_date TYPE sy-datum,
      l_day TYPE p,
      itab TYPE TABLE OF sy-datum.

l_date = begin.

WHILE l_date <= end.

  CALL FUNCTION 'DAY_IN_WEEK'
       EXPORTING
            datum = l_date
       IMPORTING
            wotnr = l_day.
  IF l_day = day.
    APPEND l_date TO itab.
    l_date = l_date + 7.
    EXIT.
  ENDIF.
  l_date = l_date + 1.
ENDWHILE.

WHILE l_date <= end.

  APPEND l_date TO itab.
  l_date = l_date + 7.
ENDWHILE.

I thank you very much !

Ramiro

can you please tell me how can I replace

PARAMETERS: begin TYPE sy-datum,

end TYPE sy-datum,

through select-options fields instead parameters.

Additional what happens if end date is not selected ?

How can prevent an error ?

hi give some condition for the end value if the end is not defined..

DATA: l_date TYPE sy-datum,

l_day TYPE p,

itab TYPE TABLE OF sy-datum.

select-options: begin for sy-datum no intervals,

end for sy-datum no intervals.

data: day TYPE c.

l_date = begin.

if end is initial .

end = end + 20 .

endif .

WHILE l_date <= end.

CALL FUNCTION 'DAY_IN_WEEK'

EXPORTING

datum = l_date

IMPORTING

wotnr = l_day.

IF l_day = day.

APPEND l_date TO itab.

l_date = l_date + 7.

EXIT.

ENDIF.

l_date = l_date + 1.

ENDWHILE.

WHILE l_date <= end.

APPEND l_date TO itab.

l_date = l_date + 7.

ENDWHILE.

A few changes that should avoid an error, The write sentences are just there for me to debug.

The above suggestion seems ok if you want to use select-options, because of the nature of the problem I don't think that is possible to use ranges and multiple selections

PARAMETERS: begin TYPE sy-datum OBLIGATORY,
            end   TYPE sy-datum OBLIGATORY,
            day   TYPE c OBLIGATORY.

DATA: l_date TYPE sy-datum,
      l_day TYPE p,
      itab TYPE TABLE OF sy-datum.

AT SELECTION-SCREEN.
  IF end < begin.
    MESSAGE e001(00) WITH 'End must be greather than begin'.
  ENDIF.

  IF NOT day CO '1234567'.
    MESSAGE e001(00) WITH 'Day must be from 1 to 7'.
  ENDIF.


START-OF-SELECTION.
  l_date = begin.

  WHILE l_date <= end.

    CALL FUNCTION 'DAY_IN_WEEK'
         EXPORTING
              datum = l_date
         IMPORTING
              wotnr = l_day.
    IF l_day = day.
      APPEND l_date TO itab.
      WRITE / l_date.
      l_date = l_date + 7.
      EXIT.
    ENDIF.
    l_date = l_date + 1.
  ENDWHILE.

  WHILE l_date <= end.
    WRITE / l_date.
    APPEND l_date TO itab.
    l_date = l_date + 7.
  ENDWHILE.
