24 hour business day, excluding holidays

[lholodnak]

Hi, I'm using crystal reports 10, with a oracle 9i database and have created a report defining the number of hours it takes to complete a work order. The business hours formula below is working just fine, but I need to exclude holidays from the total. Can someone help me add that part to this formula? thanks, Lisa


//CALCULATE THE NUMBER OF BUSINESS HOURS
//BETWEEN FirstDateTime AND LastDateTime
//INCLUDING HOLIDAYS IN THE TOTAL

//!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!//INPUT REQUIRED _ INPUT REQUIRED _ INPUT REQUIRED

//Replace datetime(2001,12,23,11,50,0) with your starting //date
DatetimeVar FirstDateTime:= {SERVICE_REQUEST.SRVC_RQST_GENERATION_DT};
//Replace datetime(2001,12,26,10,0,0) with your ending //date
DatetimeVar LastDateTime:= {WORK_ORDER.JOB_END_TM_DT};
//Replace Time(09,00,00) with your business starting time
TimeVar BusinessStartTime:= Time(06,30,00);
//Replace Time(17,00,00) with your business ending time
TimeVar BusinessEndTime:= Time(15,00,00);


//!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
//END INPUT REQUIRED _ END INPUT REQUIRED _ END INPUT

//Other variables used in the formula
Numbervar HoursInADay:= (BusinessEndTime - BusinessStartTime)/3600;
Numbervar Days;
Numbervar Weekends;
Numbervar Hol;
Numbervar Finaldays;
DateVar StartDate;

Hi Ido, thank you for responding, I did try that but and it works in a separate formula, but I'm unsure of where to insert it in this formula. Could you help me here. Lisa
