For date, time, and datetime
data items, you can
derive a hierarchy automatically. To derive a hierarchy, right-click on a date, time, or
datetime
data item in the
Data pane, and then select one
of the following values:
Create Date Hierarchy
creates a hierarchy with levels for year, quarter, month, and day. Depending on the
format of the data item, some of the levels might not be created.
Create Date and Time Hierarchy
creates a hierarchy with levels for year, quarter, month, day, hour, minute, and second.
Depending on the format of the data item, some of the levels might not be created.
Create Time Hierarchy
creates a hierarchy with levels for hour, minute, and second. Depending on the format
of the data item, some of the levels might not be created.
New calculated items
are created for each level in the hierarchy. By default, the new calculated
items are hidden in the Data pane. If you
delete a derived hierarchy, then a window appears. The window enables
you to delete the calculated items that are associated with the hierarchy.
