A Dynpro (Dynamic Program) is a concept used in SAP to describe the user interface (UI) technology used for developing screens and dialogs in SAP applications. Dynpros are used to create interactive screens where users can input data, view information, and interact with the SAP system.
Key features of Dynpros include:
- Screen Elements: Dynpros support various screen elements, such as input fields, selection fields, buttons, checkboxes, radio buttons, tabs, and table controls, to create interactive UIs.
- Flow Logic: Dynpros define the flow of control and navigation between screens using ABAP (Advanced Business Application Programming) programming language. The flow logic includes PBO (Process Before Output), PAI (Process After Input), and PBO (Process Before Output) modules.
- Field Attributes: Dynpros allow developers to define attributes for screen fields, such as field labels, field lengths, field types, and field validations, to control the behavior and appearance of the UI elements.
- Screen Painter: SAP provides a Screen Painter tool within the ABAP Workbench (SE80) for designing and editing Dynpro screens visually. Developers can use drag-and-drop functionality to add screen elements and define their properties.
- Data Binding: Dynpros support data binding to connect screen fields with data objects and variables in the SAP system. This allows for data input, retrieval, and manipulation within the Dynpro screens.
Dynpro technology is widely used in SAP applications for building transactional screens, input forms, reports, and custom UIs. It provides a flexible and efficient way to create interactive user interfaces that integrate seamlessly with the underlying SAP business logic and data. While Dynpros remain a fundamental part of SAP UI development, SAP has introduced newer UI technologies like SAPUI5 and SAP Fiori for building modern, responsive, and user-friendly interfaces in recent years.
