The goal of the ABAP Workbench Foundations (BC) course is for you to gain a detailed knowledge of the fundamental concepts of ABAP. In this course, students gain knowledge of the fundamental concepts of ABAP and learn how to comfortably and efficiently work with the ABAP Workbench tools . ABAP/4 Development Workbench. Objectives Chapter 2. The ABAP/4 Programming Language. ABAP/4 Development Workbench Architecture. ABAP/4 : General.

The ABAP runtime system copies the data records to the target area row by row using a loop. Using Selection Options When Accessing the Database The above example shows how you can b4c00 database selection to a certain range using a selection table.
Course Description for BC
If you want to change the contents of the internal table, you must first change the value of the components within the loop and then overwrite the internal table row using the MODIFY statement. You reduce the volume of data that you need to read from the database abwp you create the basic list.
Then the system processes the relevant event block in the ABAP program. Program and selection screen report transaction.
This allows the navigation area to be used in a very flexible manner. For compatibility reasons you can also define an internal table directly: Technically speaking, however, vc400 are three different types of screens: Choose Professional User Transaction.
Bc4000 with Internal Tables Key definition The key columns and their sequence define the criteria by which the table rows are absp. If, for example, a user wishes to execute your program and there is still no generated version, the system will use the active version for generation. Double-clicking on an object that does not have an object list means the object is displayed using the respective tool in the tool area.
You can display the contents of up to eight data objects. All output from the event blocks that create the lists and from the modularization units processed before a list is sent, is temporarily stored in the list buffer.
BC400 Introduction à ABAP Workbench
For example, if you create a list containing data from a very large database table, you can use a selection screen to restrict the amount of that data that is selected. Changing the Element Attributes of a Field: Generation takes place automatically, but it can also be triggered explicitly. The user has the option of changing the value.
Implementing the Sample Program: Assignment anap a Change Request Note: Runtime System Sends List The layout of the subsequent list display has also been programmed into abpa processing block.
Define a work area for data retrieval and output name suggestion: An internal table with a header line consists of a work area the qbap line and the actual table body. Depending on the access type, the key can be defined as unique or non-unique. Runtime Behavior and Data Transport: You can select functions from a context menu in both screen areas.
If this is not the case, display an appropriate error message on the list. What information is displayed?
User dialogs BC The last step in development should extend the program to enable the user to change data in the database. First the values for this line buffered in bc400 HIDE area are inserted back into the corresponding global data objects.

You can adopt field attributes from data objects already defined within a program. This means that value assignments to the formal parameter affect the actual parameter directly. Lists in Executable Programs In executable programs, lists are automatically displayed after their corresponding event blocks have been processed. I Information The program is continued after a dialog box.
Higher numeric literals are mapped onto data type p. Each type of screen provides different services to the user. Introduction to the Repository Figure Do the fields belong to a structure with a globally defined type? Execute your program by entering the new transaction code.
In the context of this training course, it is sufficient to show one simple excerpt from this data model; this can be modified to suit your own needs, if necessary: Both events presented here are initiated by the ABAP runtime system exactly once each time a program is executed.
This data includes, apart from application data, the programs and the metadata that the system requires for self-management.

The example above shows one way of doing this. If you have the name of a program that accesses the database table you are searching for: Pass the internal table containing the data that has been read using the interface.
Select only those fields that have a target field in the work area. Internal Program Modularization BC If a local data object or formal parameter has the same name as a global data object, the ABAP runtime system addresses the local data object in the subroutine and the global one outside it.
