When you define a scope for the row or a column, you can:

• Specify the row/column scope, dragging selected packages on the scope box
• Define expressions for building personalized hierarchy trees
• Specify the row/column scope query, building a list of elements related through the defined criteria 

Specify the row/column scope

To specify the row/column scope

Do one of the following:

• In the Model Browser, select one or more packages and drag them to the Row/Column Scope box in the Criteria area.
  

• Click the  button next to the Row/Column Scope box and in the open dialog select the needed packages. Click OK.

• Open the matrix Specification window, click the Row/Column Scope property value cell, then click the  button, and in the open dialog select the needed packages. Click Close.

Define expressions for building personalized hierarchy trees

You can specify the criterion for building a personalized Row/Column hierarchy tree in matrices by choose from the following tree-view options:

• Select Containment to display the decomposition of elements related through the Containment relationship.
• Select Structure to display the decomposition of Part Properties related through the Composition relationship.
• Select Custom to display the decomposition of elements related through any criteria of your choice. 

By selecting Structure, you can build a custom tree-like view for the rows and columns of the matrix. Currently it is possible to build a tree hierarchy by specifying your own criteria. You can select the predefined Structure criteria which builds the same hierarchy as in the Structure Tree in Model Browser.

Select Custom, if you need to collect elements that are not necessarily owned by the same package, you can specify the query in the Row/Column Query dialog, and see the results added to it immediately.

Specifying criteria for building a personalized tree-view in a matrix

Specify the row/column scope query

To specify the row/column scope query

1. Click the Specify Row/Column Query icon in the Row/Column Scope field.
   
2. In the Row/Column Query dialog, select one of the following:
   • Containment. Select if you want that the row/column elements would be displayed as in the Containment tree. Owned elements will be collected recursively starting from the elements specified as scope values.
   • Structure. Select if you want that the row/column elements would be displayed as in the Structure tree. This option is available only when the SysML Plugin is installed.

   • Custom. Select if you want to make your own adjustments. Select the Build Hierarchy check box to recursively execute the specified expression for building multilevel hierarchy starting from the scope as the root.
     

     If you have selected Custom, specify the expression.

     

3. Click OK.
