Security roles mapped to buttons

Hi

I have spent hours trying to ascertain which roles activate certain buttons in Dynamics AX 2012 R2. I require a simple map. This button is activated by these security roles.....

I am trying to find which role turns on the Accounts Payable/Common/Purchase Orders/All Purchase Orders/'Receive' tab/Journals/PRODUCT RECEIPT without activating the Generate Product Receipt button.

PLEASE HELP!
