You can define the Contributions of Alternatives to Covering Objectives from the DEFINE MODEL > Review/Refine Model > Contributions page.
The Contributions page can be displayed by Alternatives:
or by Objectives:
By default, all alternatives contribute to all covering objectives. In most cases, particularly when the hierarchy represents a broad range of organizational objectives, alternatives may contribute to only a subset of the covering objectives. You can specify which covering objectives each of the alternatives contributes to on this page.
An alternative that does not contribute to a covering objective does not receive any priority for that covering objective. This is equivalent to, for example, saying that it does contribute and then evaluating it with a zero priority rating. If there is some disagreement about whether or not an alternative contributes to a covering objective, it is better to designate it as contributing and allow the evaluators to decide if the priority is zero or not.
Clicking on the row or column heading boxes will select/de-select all of the elements in that row/column.
A check mark
in a column or row header means that all cells in the column or row contribute.
A box mark 
in a column or row means that some but not all contribute. Blank 
means that no cells in the column or row contribute.
