Trigger:
Java
trigger AccountTrigger on Account (before insert) {
AuditAssigner.setAuditor(Trigger.new);
}
Apex Class:
Java
public class AuditAssigner {
public static void setAuditor(List<Account> accounts) {
for (User u : [SELECT Id, Audit_Code__c FROM User]) {
for (Account a : accounts) {
if (u.Audit_Code__c == a.Audit_Code__c) {
a.Auditor__c = u.Id;
}
}
}
}
}
