First step is to create 3 new fields against company as displayed in above image.

  • Navigate to below path
    <<Sage CRM Installation Directory>>\ \<<CRMINSTANCENAME>>\WWWRoot\js\custom
  • Create a new js.file and insert the below code
var sStartDate = document.getElementById('claus_start_date').value;
var sCloseDate = document.getElementById('claus_close_date').value;
var sDate = sStartDate.substring(0, 2);
var sMonth = sStartDate.substring(3, 5);
sMonth--;
var sMon = sMonth;
var sYear = sStartDate.substring(6, 10);
var sDate1 = sCloseDate.substring(0, 2);
var sMonth1 = sCloseDate.substring(3, 5);
sMonth1--;
var sMon1 = sMonth1;
var sYear1 = sCloseDate.substring(6, 10);	
var FormattedStartDate = new Date(sYear, sMon, sDate);
var FormattedCloseDate = new Date(sYear1, sMon1, sDate1);
var Diff = FormattedCloseDate-FormattedStartDate;
var DiffDays = Math.ceil(Diff / (1000 * 60 * 60 * 24)); 
var DiffMonths = Math.floor(DiffDays / 30);		   
 claus_diff_months.value = DiffMonths;
