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.

ABAP Workbench Foundations BC | Computer school Gopas, a.s.
Information about the first three techniques is available in the relevant units. Program Start Whenever a user logs on to the system, a screen is displayed.
Repository objects are often made up of subobjects that are themselves repository objects. Synchronization of Navigation and Tool Areas Navigation in the navigation area is independent from navigation in the tools area. In the data model, which is tailored for managing the necessary data, the data is stored in tables in a central database, organized according to technical criteria.
BC400 Introduction à ABAP Workbench
I Information The program is continued after a dialog box. Use the IF statement to do this.
To do this, create the required table work area as a local data object in the subroutine name proposal: When the subroutine is called, parameters are passed to it in strict sequence.
You will also learn the different transfer types of a main program to the interface of a baap The user can then change the values in the input fields.

Since each transaction code agap a Repository object, you must assign it to a package and to a change request on the following screens. Execute your program to test the result. Pass the internal table containing the data that has been read using the interface.
Unlike database tables, the system may number the rows for an internal table. For this you must define the data object for the data transport between the screen and the program using the TABLES statement.
Semantic properties, such as field labels, are stored in the data element. Then, if the statements in the subroutine are not suited to the inherited type, a runtime error may occur.
If there is no search help coupled with the structure field, the system uses the data element search help. It is therefore possible to access table rows using this index.

Make sure that the key fields of the bc4400 table SFLIGHT are available to you for creating the detail list when the user selects a flight from the basic list double-click or F2 on the corresponding row in the list.
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.
Structures in Debugging Mode You can trace the field contents of a structure by entering the name of the structure in the left column using double-click. Using global data types has several advantages: They do not serve to represent a database table in the ABAP Dictionary, but b400 a pure type definition instead.
If the authorization check does bc040, display a suitable error message from aba class BC in the status bar, and allow the user to enter a different value on the selection screen. Using translatable text elements, you can develop multi-language applications.
You can add colors and icons. Line type This is the source of the attributes of the individual columns.
Selection Screen Attributes Selection screens are input masks for value sets that restrict the amount of data read from the database. Fill the internal table and display contents 1. Enter a short description of the screen, select screen type Normal, and enter the number of the subsequent screen. The type of an interface parameter defines the type of the values actual parameters that are passed when the modularization unit is called.
Transport Layer If you are executing your own developments, you must set up a transport layer for customer developments. If you use elementary types, zbap can decide whether or not you want to specify the type of the formal parameters. In the case of functions, the opening parenthesis is part of the ID.
