All of the DETs for each of these files are maintained using the same screen in the application. What is the functional size of the transactional function after the enhancement?

HOTSPOT
An enhancement project involves both the Human Resource (HR) application and the Mail Distribution (MD) application.
The HR application maintains all data elements in the Employee logical file. The users of the HR application require validations for employee pay grade and employee job title in the Employee logical file. The employee pay grade will be validated against the Pay Grade logical file which is maintained by the Finance application. The employee job title will be validated against the Job Title logical file which is maintained by the Compensation application.
The MD application maintains two data elements in the Employee logical file. The users of the MD application require additional validations for building and floor within the employee mailing address. The building and floor will be validated against the Building logical file which is a new file being developed by this project.
The users will use the MD application to maintain the Building logical file. The users of the MD application also maintain building and floor in the Employee logical file.
