IMPACT CHANGES ERROR upon activation of extensions on production account

I have developed extension couple of days ago and I have successfully deployed the extensions to the NetSuite SuiteCommerce Site. Now, I did some changes to the extension and trying to deploy and it deployed when I'm going to activate it is throwing the IMPACT CHANGES ERROR
