Create Dynamic Collections

  • Last UpdatedMay 24, 2024
  • 1 minute read

A dynamic collection is a collection that does not have a fixed scope but evaluates its contents based on defined selection criteria.

Note:
This requires an understanding of writing PML expressions.

A dynamic collection can be created from a shared collection.

Right click on a shared collection element and select Edit Scope Selection to display the Expression Editor window.

The Expression Editor window uses a PML expression to select elements.

Expression

Specifies the content of the collection using a valid PML expression.

The validity of the expression is continually tested. If the PML expression is not valid, a warning is displayed adjacent to the text box.

Execute

Processes the PML expression and displays the results in the Results list.

Results

Displays the results of the PML expression, all elements are represented by name and type.

OK

Saves the PML expression results and closes the Expression Editor window.

Cancel

Discards any changes and closes the Expression Editor window.
