The next time you start the program, the new headers will appear in the list automatically. There you will find executable examples, even for many other keywords and programming techniques.

Each statement must end with a period. Comply with the customer namespace conventions. Each type of screen provides different services to the user.

Secondary Index As soon as you navigate to the definition of abp database table in the ABAP Dictionary, you will see information about all the technical attributes of that database table. Selection Screen Exercise Implementing the Sample Program: Working with Structures Lesson: You can write text symbols into your program in either of the following ways: The ABAP programs read data from the database level, process the data, and possibly also aba data there.

Enter a short text.

Several functions for different data types are predefined in the ABAP runtime environment. Reuse Components for Data Retrieval If reusable components abqp encapsulate complex data retrieval are available, you must use them.

You can delete screen elements simply by selecting them with the mouse and then choosing Delete. On request, the system automatically generates a documentation dialog and an input help dialog for the user.

Depending on the access type, the key can be defined as unique or non-unique. 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.

Features of Lists The main purpose of a list is to display data for the minimum amount of programming. The presentation server controls the program flow for as long as the user enters data in the input fields.

However, you can replace these with selection texts, which you can then translate into any further languages you require. Check that all of the data objects are initial. For more detailed information, select the field help F2. If the detailed data has changed between creating the basic list and displaying the screen, the system will display the wrong data. In this case, there is no need to declare the event block explicitly. If the list is large, this substantially reduces the runtime resources needed.

Following up the list structure 1. Lists also take the special requirements of business data into account: Program Start Whenever hc400 user logs on to the system, a screen is displayed.

With this in mind, this part of the unit will deal with: For compatibility reasons, you can also omit this addition. Here too, the index is maintained internally. In this example, the field list determines the columns whose data is to be read from the database.

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. In this case, you could display a message, for example. Working with Internal Tables Exercise Objectives After completing this exercise, abzp will be able to: Logical databases are data retrieval programs that return logically connected data in a hierarchical sequence. Introduction to the Repository Figure In the first two types of loop, the system stores the number of the current loop pass in the SY-INDEX field; in the case of nested loops, this always refers to the current loop.

Working with Structures Exercise Objectives After completing this exercise, you will be able to: The second example shows the syntax for reading a line in the internal table with a fully specified key. The same syntax applies to global types as does to user-defined types: In a standard table these contents are appended, in a sorted table they are inserted in the right place, and in a hashed table they are inserted according to the hash algorithm.

Inactive and Active Development Objects Whenever you create a development object, or change and then save it, the system first stores only one inactive version in the Repository. The detailed data on the screen is up-to-date. Data retrieval and filling an internal table 1. The following graphics demonstrate how this qbap done. bc4000

Testing On the other hand, if you test an executable program from the ABAP Editor, the system will access the inactive version. There you see a list of the objects that you have displayed since starting the Object Navigator in the tool area. In the SAP Sbap Application Server, presentations, application logic, and data storage can be assigned to different systems. User dialogs BC Lesson: When the ABAP runtime system accesses client-specific tables, it assumes that data should only be taken into account if it belongs to the client under which the user is logged on.
