This lesson shows you how to build an ALV grid program and use it to update transparent tables in the ABAP dictionary.
This lesson provides an overview on how to create an object oriented Advanced List Viewer(ALV) for updating customer database tables. (Z or Y)
Objective:
Create, delete and modify entries dynamically from any custom table using the object oriented ALV.
This lesson will show you how to create a more complex selection screen using radio boxes, check boxes and many other complex controls.
This lesson will show you how to enhance SAP tables to include custom fields of your own.
Apart from the enhancement type already mentioned, there are also others, such as:
You can attach an append structure with the required additional fields to most transparent table. With that you can implement additional columns in the database table of SAP applications without modifications.
Some SAP programs contain source code areas that have been commented out. If recommended by SAP, you can remove the comments to obtain addtional functionality. Technically, however, this is a modification.
This lesson talks about the different SAP User Exits that you can implement to modify
and adapt your software to meet the client's requirements without modifying SAP Core.
This lesson provides an overview of the options for adjusting the SAP standard
software to fit your client's requirements.
This lesson will teach you about the ALV Grid Control. This is the most common control used to display reports on the screen. ALV Grid controls can summarize, show totals and subtotals and print your report or export it to Excel.
The standard pushbuttons of the control can be used to execute, among others, the following functions:
Many new functions are delivered with the SAP standard version as classes
or methods. This lesson will provide you with a short introduction into
object-oriented programming and then show you how you can find existing
classes and methods in the SAP System and how you can use them from within
your program.
In this lesson, you will learn how to create and use function modules. As an example, you will call a function module for the encapsulation of a SELECT in your program.
A function module is a subroutine with the corresponding function that is centrally stored in the Function Library of the SAP system. Each function module has an interface for importing or exporting parameters. The main purpose of function modules is their reusability. Hence, they belong to the so called reuse components.
Function modules are organized into function groups. Each function group is a collection of function modules that have similar functions and/or process the same data.
A function group can contain the same components as an executable program. These include:
The interface of a function module can contain the following elements:
In this lesson, you will assign a title to your list and your screen. Furthermore, you will create a status for the list (with standard list functions) as well as a status for the screen that refers to the components of the list status.
The user interface of a screen consists of the following elements:
In this lesson you will learn how to create and work with buttons in your screen.
Implement Pushbuttons
Different pushbuttons and the program are to be implemented in such a way that the appropriate processing for the user action is executed:
