Hi,

I need help on the following req

1) I am having a custom field called as "Dealer Principal__c" in my custom object called as "Account Exceptions__c"

2) There is a lookup on my custom object called as Account__c which is a lookup to the account object


My req is i want to populate my custom field  "Dealer Principal__c"  on Account exception__c custom object with  the contact first name and last name of the contact  related to the account that i select if the contact title is set as "Dealer Principal" (This is done)

if the account record type is group account , the child accounts contact's name  is set which is having 
contact title as "Dealer Principal"  and not the group account contact  (need help on it)




My requirement is below 


1) if the account is a normal account (PDN Record type) , the contact(name) associated with that account with title "Dealer Principal" is populated to that field


2) If the account is a group account


the group account might have many child accounts , where it will check the contacts of all th e child accounts with the title "Dealer principal" and update the name correspondingly


so my case should work for both the scenarios

First scenario my trigger is working fine , just need help on second one



My trigger :

trigger updateaccountexceptions on AccountExceptions__c(after insert) {
    map < id, string > dealercontacts = new map < id, string > ();
    set < id > accids = new set < id > ();

    for (AccountExceptions__c acex: trigger.new) {
        accids.add(acex.account__c);
    }

    List < contact > cons = new List < contact > ([select Id, accountid, firstname, lastname from contact where title = 'Dealer Principal'
        and accountid = : accids
    ]);

    for (Contact con: cons) {
        string conname = con.firstname + ' ' + con.lastname;
        dealercontacts.put(con.accountid, conname);
    }

    list < AccountExceptions__c > acexlisttoupdate = new list < AccountExceptions__c > ();

    for (AccountExceptions__c acex: trigger.new) {
        AccountExceptions__c accex1 = new AccountExceptions__c();
        if (dealercontacts.containskey(acex.account__c)) {
            accex1.id = acex.id;
            accex1.Dealer_Principal_s__c = dealercontacts.get(acex.account__c);
            acexlisttoupdate.add(accex1);
        }
    }

    update acexlisttoupdate;

}
