Main factors are Month, Country and its "AC" value.

var actual = [
 {"country":"UK","month":"JAN","SR":"John P","AC":"24","PR":"2","TR":1240},
 {"country":"AUSTRIA","month":"JAN","SR":"Brad    P","AC":"64","PR":"12","TR":1700},
 {"country":"ITALY","month":"JAN","SR":"Gim P","AC":"21","PR":"5","TR":900},

 {"country":"UK","month":"FEB","SR":"John P","AC":"14","PR":"4","TR":540},
 {"country":"AUSTRIA","month":"FEB","SR":"Brad P","AC":"24","PR":"12","TR":1700},

 {"country":"ITALY","month":"MAR","SR":"Gim P","AC":"51","PR":"5","TR":200}
