As part of TCA I understand that we can use extensions to create user defined attributes. I am trying to navigate to the extensions tab under the Trading Community manager->Administration responsibility. I am not able to find the Extensions tab here. I am on R12. Can you please help me in understanding what can be the reason for this and the workaround. I am not able to access this from the Customer online super user responsibility either.It has only the Home page and no other entries added.
