Access denied: SubledgerJournalizationController for security roles on product receipt

In AX2012 while working on the security role I faced the following error while product receipt update:

Access denied: SubledgerJournalizationController

In order to resolve this issue, you need to give access to the server method, go to user role and browse to the server method node as shown below and then right click and click "New server method" 

Now click on the properties and add the following details:

The class name should be "SubledgerJournalizationOperation" and the method that needs to be added should be "Journalize".

Below is the final output that you will see once you are done:

After adding this the issue will get resolved.

Hope this helps!
