public list<Inventory_Transaction__c> ITList1{get;set;}
ITList1 = new List<Inventory_Transaction__c>();

public list<Inventory_Transaction__c> ITList2{get;set;}

public list<Transaction_History__c> THList1{get;set;}
THList1 = new List<Transaction_History__c>();

Hi,

 

If you want to deal with duplicate record issue then make use of Set in your code. Set helps in getting unique records also in last you can add all records to List by help of addAll() method.
