You've probably seen this in the content validator! This refers to a table calc or custom field that relied on a measure or dimension that were removed from your look! The table calc is looking for that field, and it can't find it.
The solution would be to either:
1) Add the measure or field that was removed
2) Remove the table calc or custom field
