Round Robin Algorithm for Contact in Salesforce

Kapil January 23, 2021

In this blog we will create a custom Round Robin Assignment for Contacts in Salesforce. Create a custom field in Contact object and use below trigger to generate the Round Robin !

Trigger

trigger contacttrigger on Contact (before insert) {
    if(Trigger.isBefore){
        Double roundRobinValue = 1;
        List<Contact> conList = [SELECT Id, Round_Robin_ID__c, CreatedDate FROM Contact where Round_Robin_ID__c  != null
                                 order by CreatedDate desc limit 1];
        if(conList != null && conList.size()>0){
            roundRobinValue = conList[0].Round_Robin_ID__c;
        }
       
        
        for(Contact c : Trigger.New){
            system.debug('###Round Robin Value : '+roundRobinValue);
            if(roundRobinValue == 3){
                roundRobinValue = 1;
                c.OwnerId = '0057F000002FrWT';
            }
            else if(roundRobinValue == 2){
                roundRobinValue++; 
                c.OwnerId = '0057F000005vkd1';
            }
            else{
                roundRobinValue++; 
                c.OwnerId = '0057F000002Fyug';
            }
            c.Round_Robin_ID__c = roundRobinValue;
        }
    }
}
