Itemset column headers

When defining an item, you can specify a label in the Itemset Column Header property. If the item is used in an itemset, this label appears as the column heading in the row and column representation of the itemset.

In reporting, the Itemset Column Header property is also used as the default short name for the field in the clinical reporting model, whether or not the item is used in an itemset. You can override this name when customizing reports.

Note: You should ensure that Itemset Column Header definitions are unique within a trial. If the Cognos reporting system finds duplicate Itemset Column Header values, it combines the items in reports.
