Report ZLLM_PROVIDER_MAINTENANCE

AI Generated documentation.

Overview

The report ZLLM_PROVIDER_MAINTENANCE is a SAP ABAP program that provides a user interface for managing provider configurations. The program consists of two main classes: LCL_APP and LCL_SCREEN. The LCL_APP class handles the business logic for loading, saving, and updating provider configurations, while the LCL_SCREEN class handles the user interface and event handling.

The program uses a database table ZLLM_PROVIDERS to store provider configurations and a function module ZLLM_COMMON to interact with the database. The program also uses encryption and decryption functions to secure the provider configurations.

Dependencies

  • SAP ABAP 7.4 or later
  • SAP GUI 7.4 or later
  • Database table ZLLM_PROVIDERS
  • Function module ZLLM_COMMON

Details

Class LCL_APP

The LCL_APP class has the following methods:

  • LOAD_PROVIDERS: Loads provider configurations from the database table ZLLM_PROVIDERS.
  • SAVE_PROVIDER: Saves a provider configuration to the database table ZLLM_PROVIDERS.
  • ENCRYPT_AUTH_VALUE: Encrypts a provider configuration value using the ZLLM_COMMON function module.
  • DECRYPT_AUTH_VALUE: Decrypts a provider configuration value using the ZLLM_COMMON function module.
  • BUILD_FIELD_CATALOG: Builds the ALV field catalog for the provider configurations.
  • REFRESH_DISPLAY: Refreshes the displayed ALV data.

The LCL_APP class uses a private data structure PROVIDERS to store the loaded provider configurations.

Class LCL_SCREEN

The LCL_SCREEN class has the following methods:

  • START: Starts the program and initializes the user interface.
  • PAI: Handles the PAI (Post-Activation) event, which is triggered when the user performs an action on the ALV.
  • PBO: Handles the PBO (Post-Create) event, which is triggered when the ALV is created.

The LCL_SCREEN class uses a private data structure APP to store the LCL_APP instance.

Logic Flow

The program uses the following logic flow:

  1. The LCL_SCREEN class starts the program and initializes the user interface.
  2. The user interacts with the ALV, performing actions such as adding, changing, or deleting provider configurations.
  3. The LCL_SCREEN class triggers the PAI event, which calls the LCL_APP instance's HANDLE_ACTION_ADD, HANDLE_ACTION_CHANGE, or HANDLE_ACTION_DELETE method.
  4. The LCL_APP instance performs the requested action, such as saving a provider configuration or encrypting a value.
  5. The LCL_APP instance updates the PROVIDERS data structure and triggers the REFRESH_DISPLAY method to refresh the ALV data.
