Hi Gopal,

You can try below Trigger as per your requirement. 
trigger CaseAssignmentTrigger on Case (after insert) {
    
    set<id> caseids = new Set<id>();
    list<case> CaseList = new list<case>();
    for(Case c : trigger.New)
    {
        caseids.add(c.id);
    }
    
    for(Case c: [Select id, Owner.Profile.Name from Case where Id IN:caseids])
    {
        if(c.owner.Profile.Name == 'Customer Community User')
        {
            CaseList.add(c);
        }
    }
    if(CaseList.size() > 0)
    {
    Database.DMLOptions dmo = new Database.DMLOptions();
    dmo.assignmentRuleHeader.useDefaultRule = true;
    Database.update(caseList, dmo);
    }
}
You need to have a Active Case Assignment Rule.

Let us know if that helps you.

Hi Gopal,

I think, this will help you 
trigger CaseAssignment on Case (after insert,after update) {
    //Variable decleration
    List<Case> caseList = new List<Case>();
    User integrationUserObj = new User();
    
   //Fetching the assignment rules on case
    AssignmentRule AR = new AssignmentRule();
    AR = [select id from AssignmentRule where SobjectType = 'Case' and Active = true limit 1];

        //Creating the DMLOptions for "Assign using active assignment rules" checkbox
    Database.DMLOptions dmlOpts = new Database.DMLOptions();
    dmlOpts.assignmentRuleHeader.assignmentRuleId= AR.id;

   
    
    if(Trigger.isAfter && Trigger.isInsert){
        //Fetching the Community User details
        integrationUserObj = [SELECT Id, Name FROM User where Profileid= '00e28000001hb4Y' LIMIT 1];
           
        for (Case caseObj : Trigger.new) {
            if (caseObj.OwnerId  == integrationUserObj.Id) {
             Case newCase = new Case(Status = 'New') ;
                //Setting the DMLOption on Case instance
              newCase.setOptions(dmlOpts);
                caseList.add(newCase);
            }
        }
   
        
        Database.update(caseList, dmlOpts);
    }
}

Please let me know if you have any query.
