Documentation

Definition

Packages extend the concept of development classes to improve modularization, encapsulation, and decoupling in the SAP System.

Development classes, used until now, are simple containers for development objects, provided with a transport layer that specifies how they were to be transported. As an enhancement to development classes, packages include the following attributes: nesting, interfaces, visibility, and use accesses.

• Nesting is the ability of a package to include other packages within the package hierarchy.
• Visibility is an attribute of package elements. A development element can be visible from outside the package. (It is always visible inside its own package, though not necessarily all the packages embedded in this package). A development element is visible externally if it is included in at least one package interface.
• The use access gives a package the right to use the development elements in the package interface of another package. Note that this right is one-way only.
