I have an use case to restrict maturity change of Manufacturing items depending on user property but in Server Side BL PLMCheckMaturity it is not possible to read User Profile or evel PLMQuery not possible in Server Side BL. Then I am trying to read any kind of file (in resource table) text,xml etc but I didn't find any option to read file as well? Can anyone guide me how can I solve this use case?
