Set<Id> IdSet = new Set<Id>();

   for(Banking__c mp:trigger.new)
   IdSet.add(mp.Id);
     
   List<Customer __c> BankingstubToCreate = new List<Customer __c>();
   for(Banking__c mp:trigger.new)
   {
    if(IdSet.size()>0 )
   {
     Customer __c s = new Customer __c();
      s.Banking__c =mp.Id ;
      mccystubToCreate.add(s);
   }
   }
   
   if(BankingstubToCreate.size()>0)
   {
    Database.SaveResult[] lsr = Database.insert( BankingtubToCreate, false);
