Use

The nested package concept allows you to release different elements of an interface at different levels. At each separate level of nesting from the inside outwards, you can decide whether or not a visible element in an embedded package should remain visible to the next level outwards. In this way, you can specify, for example, that development objects can only be used within a main packages and not between two main packages.

Conversely, if you want visible element within a main package to be available for other main packages, then you must extend visibility over several levels until the other main packages can see it. The following graphic clarifies this concept.

Prerequisites

Only the innermost sub-package has an interface with the elements assigned to it.

Procedure

To extend the visibility of interface elements from a sub-package outwards:

  1. Choose the package immediately surrounding this sub-package.
  2. Create an interface for this package.

    3. For more information, see Creating Package Interfaces.

  3. Double-click the name of the interface you have just created.

    4. The system displays it.

  4. Choose the Visible elements tab.
  5. Choose the Add package interface button.

    6. The system displays the Choose the package interface you want to add dialog box.

  6. Choose the interface belonging to the inner sub-package.
  7. Choose This graphic is explained in the accompanying text to confirm your entries.
  8. Choose This graphic is explained in the accompanying text to save.

Result

You have extended the visibility of the elements in the embedded packages one level outwards. These elements have the same attributes in interfaces at all levels and are now available to additional users at every nested level that has an interface to them.
