When you created a default layout, a field was not generated for the column in the message. The most likely cause is that a summary was not placed in the data model correctly. For example, you may have specified the source of a summary column to be a column in a group above the summary's group. This is not allowed.
Action:
Debug your data model and redefault your layout.
