z_locked_users_report
The z_locked_users_report project is an application implemented using ABAP Object Services, designed primarily to manage and report on the status of user accounts — specifically, those that are locked or unlocked. This project leverages the power of SAP's ALV (ABAP List Viewer) for a user-friendly interface, facilitating administrative tasks related to user management in SAP systems.
User Lock Status Report
implementedCore
Displays a list of locked or unlocked users based on a selection entered by the user. This is executed through an ABAP report, providing a straightforward interface for viewing user status directly within the SAP environment.
User Navigation
implementedUI
Facilitates seamless navigation to the SU01 transaction code for user maintenance directly from the report interface, enabling a more integrated user management experience within SAP.
Overview
The z_locked_users_report project is structured around SAP's ABAP programming runtime environment. It involves various components to manage and present data about user account statuses. The architecture is designed to integrate seamlessly with external services, emphasizing both interaction through configuration and data presentation via SAP's ALV (ABAP List Viewer) framework.
Primary Components
User Management Report Module
Generates reports on user lock statuses and facilitates navigation to user administration.
- cl_salv_table
- cl_salv_events_table
- cl_salv_columns_table
- if_salv_c_cell_type
- cx_salv_msg
- cx_salv_not_found
Design Patterns
Model-View-Controller (MVC)
Separates data handling (Model), user interaction (View), and application logic (Controller) to improve modularity and maintainability.
Found in: The `Z_LOCKED_USERS.abap` file represents the Model and Controller that handle data retrieval and logical operations. The ALV framework acts as the View by rendering the data display.Event-Driven Programming
Implements event handling for user interactions with the ALV grid
Found in: The lcl_alv_handler class implements event handling for grid clicksFactory Pattern
Uses cl_salv_table=>factory for creating ALV instances
Found in: The display_data form utilizes the factory method pattern through cl_salv_table=>factoryLanguages
