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.

Element attributes In this dialog box, all the attributes of a screen element are displayed.
Typing Structured Data Objects Figure Selection Options If the user enters several values or intervals for a selection option and chooses Execute, the system places them in the internal table. The individual data records in an internal table are known as table rows or table entries. After its completion, the runtime system sends this list as a screen to the presentation server.
Screens and Data Transport You can use the LIKE addition to refer to the type of a data object already defined. The system only fills those components that have identical names to columns in the database table. Setting breakpoints and changing field abp 1.
Transaction Codes Task 1: In this case, for the single record operations, the system identifies the row to be processed. Suitable search criteria are available for the various repository objects.
Sorting a Standard Table You can sort standard tables by the table key or by any column, simply by entering the column name after the BY addition to the SORT statement. All other products mentioned are trademarks or registered trademarks of their respective companies.
Start your program from the navigation area, and the bx400 will use the active version. Except for the first query, all further branches are optional.
ABAP Workbench Foundations [BC400]
Internal tables are therefore a simple way of processing large data sets in a structured manner. HIGH Contains the upper limit of an interval. Result Model solution without optional exercises: If you have defined a foreign key relationship, the resulting value combinations abal appear in the input help on the screen.
Repository objects are automatically assigned to a transport route on the basis of their belonging to a particular development class and their actual function. Which field values are copied? Certain graphics will, however, be enhanced to include these details whenever they are relevant to ABAP programming.
An internal table with a header line consists of a work area the header line and the actual table body. Repeat the exercise 1. Searching for Database Tables You have different options for searching for database tables: Working with Internal Tables Key definition The key columns and their sequence define the criteria by which the table rows are identified.
However, you should avoid doing this wherever possible. When you are creating a screen, the system will ask you to enter screen attributes. Check for display authorization for airlines II 1. By specifying the type of the formal parameters, you ensure that only actual parameters of that type can be passed to the subroutine. Working with Structures Lesson: Enter a short description of the screen, select screen type Normal, and enter the number of the subsequent screen.
There are two different ways to do this: The system, depending on the message text, inserts these values into the message text. ABAP Program with Several Event Blocks and a Selection Screen In all of the programs that we have seen so far in this course, only one event block has been programmed in addition to the declarative statements.
However, if you change a parameter listed after USING in the subroutine, you receive a warning in the extended program check. Log on to the training system 1.
Objective In the following sections, we will develop a program step by step. Thus within the subroutine, you address the data that has been passed using the formal parameters. You can manage all necessary data, without redundancies, using these relationships.

Developing Programs and Organizing Developments Exercise 2: Zbap Blocks Event blocks are b400 in a fixed sequence designed for list processing: Therefore you can use it as a central data type definition, as is the case with a structure. Lists Exercise Objectives After completing this exercise, you will be able to: Features of Screens Screens are made up of more than just a screen layout with input and output fields.
