Hi ShaqAX,
I am not aware of such a role or privilege.
I think that something like this will be very difficult to realize.
Why?
Imagine that you have a role as GL accountant and can post GL journals.
GL journals allow you to post transactions into subledgers (AP, AR, Project, etc.).
Even if you don't have a right to go to those subledgers you could still influence them by making postings in an ordinary GL journal.
I think that it is doable restricting the access to GL only but that it would be quite cumbersome and time consuming to make all the necessary setup and put the restrictions in journals, forms, etc. in place.
Why do you need this kind of restriction?
Best regards,
Ludwig
