CRUD Form entity

A CRUD Form entity generates the user interface for the program. CRUD forms are used to Create, Read, Update, and Delete data from a database.

A CRUD form entity is represented as a 4fdm file which can be opened and edited in Form Designer.

When a CRUD form entity is implemented from the diagram, the 4fdm file is created as well as 4gl source files containing the program logic to access and manipulate the database tables contained in the form.

Any changes to the CRUD form entity properties in the BA diagram or in the 4fdm file are included in the subsequent re-generating of the program code.

The generated code can be customized.

Properties can be set specify how the form should behave during the various states (DISPLAY, MODIFY, ADD, SEARCH).

If your form has a valid relation on the BA diagram to a Report entity, additional actions are generated for the Toolbar and Topmenu to launch the report. The Report Option properties are used to define which report actions should be generated.

Important: This feature is not supported on mobile platforms.
