Enable In App purchase is not shown

i am following the below link...

http://mobile.tutsplus.com/tutorials/iphone/iphone-sdk-in-app-purchases/

In that link they have given like below

"After logging into the Provisioning Portal, select the “App IDs” tab. Click “New App ID.” You will need to enter a common name and a unique bundle identifier. The common name will be used to identify this App ID within the Provisioning Portal and the Bundle Identifier is a unique identifier for your actual application binary. When developing an application that will use in-app purchases, you must use a full Bundle Identifier. No “wild card” IDs are allowed. Click submit. You will be taken back to the main App IDs page. Find your newly created App ID in the list, and then c开发者_如何学JAVAlick the “Configure” link to the right of it.On the “Configure App ID” screen, select the check box next to “Enable In App Purchase” and click the “Done” button:"

But for me...

In the Provisioning portal, "Enable In App Purchase " check box is not shown

But enable for Apple Push notification service is shown..

why the "Enable In App Purchase" is not shown…

Looks like Apple's policy changed, according to the How To, in the section "Registering an App ID for In App Purchases and Game Center":

All explicit App IDs are automatically enabled for In App Purchase and Game Center. Wildcard App IDs and duplicates of existing explicit App IDs are ineligible for In App Purchase and Game Center.
