Hi Sudhir,

You are getting NPE due to "GetReseller" is not initilize with any value.

You might have to create new instance of Assets or fetch existing Assets from database. Below is sample constructor for your reference.

public storelookup(){
     GetReseller = new Asset();
       
        // GetReseller = [select id, AccountId from Asset where ...]
    }

Hope this will solve your problem.

Hi Sudhir,

try below code..

public with sharing class storelookup{

   public Asset GetReseller{get;set;}
  
   public void processSelected() {
        
        GetReseller=new Asset();

        GetReseller=[SELECT AccountId from Asset limit 10];
		
        SUDHIR__c  TempAssetList = new  SUDHIR__c();
      
           TempAssetList.test__c = GetReseller.AccountId;
      
              Insert TempAssetList;
   
   }

}
