If any transaction codes are not available in end user role, here is the procedure to follow.
1 - Advise the user that what he's trying to access is not available in the system to any end user and ask for a justification
2 - Transfer or add a note to the responsible functional team (internal) explaining the situation and asking if there are other alternative transactions available
One of the 3 scenarios below will happen
1 - The user cannot have it and there's no alternative, in this case the request can be closed by explaining the situation to the user
2 - The functional team provided an alternative, in this case you can proceed with the request based on the alternative transaction, remember to explain to the user
3 - The functional team said this could be granted to end user, in this case explain to the user, open a role modification request on behalf of the user and close the original request.
