How to calculate the number of days worked for a given period

Question

I need to calculate the number of days worked by contractor employees for a time period to be entered by a user. I am building a query on an infoset which contains employee information including contract start date and contract end date for the employee.
Ideally I'd like the user to enter the time period which should be reported on e.g. 01.08.2009 to 31.08.2009
The report should then identify all the contractor employees which were working during this period and to work out how many days they worked during this period. Obviously the contract start and end dates could fall both inside and outside the reporting period.
Can this be done and if so, do you have any suggestions as to how to do it?
Thanks.

hi
So here you will first have to load the master data table employee in one internal table and read this table with the variables entries.
Your code in the reporting exit should look like that.

data : wa_employee type /bi0/pemployee.
When 'ZDATE1'
if i_step = 2.
LOOP AT i_t_var_range INTO loc_var_range WHERE vnam = 'ZDATE2'.
clear l_s_range.
clear wa_employee
1- select the entries from table employees
select single employee dateto datefrom
from /bi0/pemployee
into corresponding fields of wa_employee
where dateto le loc_var_range-low
and datefrom ge loc_var_range-high.
if sy-subrc eq 0.
CALL FUNCTION 'FIMA_DAYS_BETWEEN_TWO_DATES'
   EXPORTING
       i_datum_von  = wa_employee-datefrom
       i_kz_ult_von = 'X'
       i_datum_bis  = wa_employee-dateto
       i_kz_ult_bis = 'X'
       i_szbmeth    = '1'
   IMPORTING
      e_tage       = no_days.
       l_s_range-low  = no_days.
       l_s_range-sign = 'I'.
       l_s_range-opt  = 'EQ'.
      APPEND l_s_range TO e_t_range.
          ENDIF.
        ENDIF.
endloop.
ENDIF.
