Topic Objectives


ABAP Dictionary and its uses


• Describe the use of the Data Dictionary (DDIC)• Explain the different components of the DDIC• Explain how to navigate to the DDIC or one of its components• Define DDIC Objects such as Tables, Structures and Views• Define Table Types,Data Elements &Domains and their interrelationship

• Define Search Helps• Define Lock objects

What is the Data Dictionary?The Data Dictionary:• is a system-independent

interface to a database• is a “virtual database”

containing metadata (data about data)

• provides tools for data manipulation and data processing

• is also called DDIC or ABAP Dictionary

Necessity of Data Dictionary

• The DDIC facilitates the development of platform independent applications

• The DDIC eliminates the need for programmers to be concerned about specific storage locations, drive and directory names, etc.

Difference between Domain &Data Element

DomainDefines Technical Attributes such as data type,length,allowed values,etc.A domain can be part of several data elementsUsed to define data elements,restrict values (using value range, value table, etc)

Data ElementDefines semantic attributes such as display length ,short text, long text,etc.A Data Element can point to only one domainUsed to define fields of tables and screens.

Foreign Keys

Uses:• Maintain data integrity• Provide help texts• Create aggregate dictionary objects

Prerequisites:• The foreign key text field and primary key of the check table must share the same domain• A value table must exist for that domain.

Creating Foreign Keys

Cardinality

• Cardinality defines the type of relationship between two tables

• The cardinality of a foreign key indicates how many dependent records a record in a check table may have

Topic Objectives


Using the Menu Painter


• Explain the uses of a Menu Painter

• Describe the process of defining and Testing a GUI Status

GUI Status and the Menu Painter

Module Pool

Screens

GUI Status

• You define a GUI Status using the Menu Painter (SE41)

• You can define multiple screens and GUI Statuses for a Module Pool

• The Screens and GUI Statuses are called and controlled by “Modules” in the Module Pool

• After receiving input from user, the Screen passes control to the Module pool (Screen’s Flow logic does this) through the GUI Status

• The Screen acts as a container for the GUI Status

• A GUI Status can be associated with several screens and vice versa

Creating a GUI Status – Step 1 of 6

After entering the names of the Module Pool and GUI Status, Press the “Create” button

After entering the names of the Module Pool and GUI Status, Press the “Create” button

Prerequisite:• Module Pool Program• Screen (for testing)Since we have already created a Module Pool and a Screen in a previous section, we are going to use the same.
