Component documentation Package Builder  Locate the document in its SAP Library structure

Purpose

The Package Builder tool allows us to implement the concept of the package in the ABAP Workbench for the first time ever. Packages are designed to help developers modularize, encapsulate, and decouple units in the SAP System. They are a further development of the concept of the development class used today and contain additional semantics.
In particular, the Package Builder is used to migrate existing development classes to packages, making it a new tool for developing and maintaining development classes.

The first projects to use the package concept come from the mySAP Workplace area. The emphasis is on technically decoupling resources from the Core R/3 System, so that different products can follow different release cycles.

How to Call

Call the Package Builder using either transaction SE21 or transaction SPACKAGE.

Scenarios and Use of Packages

Packages can be either provider (server) or user (client) packages. Provider packages offer development elements (function modules, BAPIs, classes, ABAP programs, types, and so on) to other packages using one or more interfaces. A provider can also be a user, availing itself of the services of other packages.

In the documentation that follows, we have assigned a variety of scenarios to each of these two roles (provider and user). Each scenario explains how you use the Package Builder and which functions are relevant.
