Writing Custom Plan Attributes Algorithms for Members of the Variant Baseline
In the Product Family Matrix Editor, you can view the following plan attributes associated with a module variant:
Deadline
Health Status
The action to view Plan Attributes for the variant baseline member link is available from the following areas:
Variant baseline member attribute pane in Matrix Editor.
Table view of the configurable product structure display in Matrix Editor
Table view of the cell display in Matrix Editor (only when using multiple variant baselines)
Objects table of a variant baseline
Variant baseline Where-Used table for parts
You can write algorithms to update the Deadline and Health Status attributes of FloatingBaselineMember objects on the basis of changes happening in these attributes or to the related activities.
* 
When you configure algorithms for the Deadline and Health Status attributes, these attributes must be configured as read-only from the Type Manager, so that manual updates through the user interface are restricted. For more information, see Working with the Type and Attribute Management Utility.
