"Same as Customer Address" option not available in billing detail tab of credit card information

Hello All,

We are having Sage ERP Accpac 500 (Version 6.0A). I have recently integrated Sage ERP Accpac Payment Processing 6.0A module to process Credit card payment. Everything went well and we are able to charge customer's credit card using Sage Payment System successfully. We are facing a problem that when entering order billing detail on the Credit Card Information tab, there is no such option like "Same as Customer Address" (checkbox). I saw this in each tutorial and it is very useful feature.  The option i am taking is this. http://www.greytrix.com/blogs/sageaccpacerp/wp-content/uploads/2013/03/4.-Credit-Card-Information.jpg

Can anyone guide me on this how to enable this feature? 

Thanks a lot.
