How to restrict default values population(IPopulateValuePlugin) only for Renewal quote on SFDC?

[Muthukumaran]

The below plugin is will apply the default values only for the New/amendment Quote.

global class DefaultValues extends zqu.CreateQuoteController.PopulateDefaultFieldValuePlugin{
  global override void populateDefaultFieldValue
      (SObject record, zqu.PropertyComponentController.ParentController pcc)
  { 
                  String quoteType = ApexPages.currentPage().getParameters().get('quoteType');
            String subId = ApexPages.currentPage().getParameters().get('subscriptionId');

      if (quoteType == 'Subscription' || quoteType == 'Amendment')
      { 
      record.put('zqu__InvoiceSeparately__c', true);
      record.put('zqu__InitialTerm__c', 24); 
      record.put('zqu__RenewalTerm__c', 24);
      record.put('zqu__ValidUntil__c', Date.today().addDays(7));
      record.put('zqu__PaymentMethod__c', 'ACH'); 
        }
      }
    }
  }

I hope this Helps!
