To subtract business days from a given date, the following code can be used in a Special Browser script field that will populate a Calculated Value Custom Field with the new date.
In the Special Browser script field you define the function that subtracts the a number of days from a given date
function bus_date_subtract() { var frm=document.form1; // or document.frmevent at Level 2 or 3 var formatstr="dd/mm/yyyy"; var start=ConvertDateStr(frm.startdate.value,formatstr); var sub=-5; for(i=-1;i>sub;i--) { var cdate=dateadd(start,'D',i); var cdatetemp=new Date(); var cdatearr=cdate.split("-"); cdatetemp.setFullYear(parseInt(cdatearr[0]),parseInt(cdatearr[1])-1,parseInt(cdatearr[2])); if(isHoliday(cdate)||cdatetemp.getDate()==0||cdatetemp.getDate()==6)sub--; } document.frmevent.cf_1742956 .value=cdate; } bus_date_subtract();
In Expression section of the Calculated Value Custom Field you would call the function:
bus_date_subtract();
Note: The function definition can be changed to accept parameters (fields containing dates) that are passed at the time of calling the function from any Calculated Value Custom Field.
