Understanding the Layers of Invoicing Documents


When dealing with invoicing documents within the ABAP Dictionary, it is crucial to recognize the three distinct layers involved:

  • Database Layer: The database layer stores invoicing documents using specific transparent tables within the ABAP Dictionary. These tables are dedicated to storing and updating the documents, and they are accessed through different modules, ensuring data integrity and efficient operations.

Database Layer example

  • Logical Layer: In the logical layer, invoicing documents are managed using logical tables. These tables provide a structured approach to organizing and manipulating the data effectively. The invoicing program utilizes these logical tables to efficiently handle the documents and streamline processes.

Logical Layer example

  • Display Layer: The display layer focuses on enhancing the visual representation of invoicing documents. It allows users to interact with the data in a user-friendly manner. The structures in the display layer resemble those in the logical layer but include an additional customer include that enables the incorporation of supplementary fields for display purposes.
