Creating a Package using Package Builder 

Use

You can create a Structure, Main or Normal package using the Package Builder.

Structure packages form the top level in the package hierarchy.. The main package is primarily a container for development objects that belong together. However, you must store development objects in development packages, not in the main package itself. The structure and main packages cannot contain development objects. Several main packages can be grouped together to form a structure package.

The semantic units within the main package are represented by the development packages. They contain the assigned development objects, along with the associated sub-packages if they exist. This is known as nesting.

Prerequisites

...

·        You have the authorization to create packages in the development system. Further, to create structure and main package, additional authorizations are required.

·        Main packages can be created only inside a structure package

·        Development packages can be created only inside a main package or another development package.

Procedure

You create a structure, main or normal package in a similar procedure to the one described below. Only the type of package is different and is specified during creation.

       1.      Open the Package Builder initial screen (SE21) or from SE80 by choosing the repository type ‘Package’.

       2.      In the Package field, enter a name for the package that complies with the tool’s Naming Conventions

Within SAP itself, the name must begin with a letter from A to S, or from U to X.

       3.      Choose Create.

The system displays the Create Package dialog box.

       4.      Enter the package attributes.

If you are creating a main package, then select the checkbox Main Package. This checkbox appears only if you have the appropriate authorization (see Prerequisites).

In the field Package Type, select the type of package you are creating. The type can be Structure, Main or Development Package. This field will appear only if you have the authorizations to create Main or Structure packages.

       5.      Save.

       6.      Assign a transport request in the dialog box that appears.

Result

You have created your package and can now define a structure within it. Generally, you will continue by adding subpackages to the main package. They themselves will contain the package elements you have assigned.
