For example, GESSIH (Sales Invoices) function code.
There is an option, E (Open items).
My client would like to access to "Open items edit" screen from GESSIH main function so I would add E (designated Option code) to options for GESSIH functional authorization.
Additionally, the client would like that the "Open items edit" screen to be view only as a manager's assurance to prevent possible worker's fat finger mistakes with accidental edit when intent to read the field only.
How can I do it in this case as functional authorization is one level only?
