Unit 2

Data objects in the ABAP Dictionary

Unit Overview

In this chapter, you will become familiar with the different options for mapping data objects in the Dictionary

Unit Objectives

After completing this unit, you will be able to:

•Create domains and use them in data elements

•Define data elements and use them as the basis for defining data objects in ABAP programs

•Define structures and use them as the basis for defining data objects in ABAP programs

•Define internal tables and use them as the basis for defining data objects in ABAP programs

•Define complex (nested / deep) structures and use them as the basis for defining data objects in ABAP programs

•Define global constants with the help of a type pool and use them in ABAP programs

•Create Tables

•Use the two-level domain concept

•Define the technical settings of a table

•Create and use include structures

•Describe table types in the SAP system apart from the transparent tables

•Distinguish pooled and cluster tables from one another

•Describe the advantages and disadvantages of pooled and cluster tables.
