• Matrix Name
• Matrix Description
• Link created
• Link deleted
• Axis item renamed
• Axis item rescoped / scoping item renamed

If you change any of the above values in Modeler, the changes will automatically be reflected in the matrix.

To view or remove the scope name from the rows and columns, do the following:
Select the Columns or Rows checkboxes to display the scope name in the row/column headings. This is the same as setting the values of rowItemsShowScope and columnItemsShowScope to TRUE or FALSE in the property pane of the matrix in Modeler. This configuration is written in to Modeler; therefore, if you refresh or regenerate the matrix, the changes are not reset.
