For graphs and OLE objects, you do not select the range when you call the

function. The range has already been determined by the Rows setting on the

Data property page (the Range property), and the aggregation function uses

that range. Settings for Rows include the following:

• For the Graph or OLE presentation style, Rows is always All.

• For Graph controls, Rows can be All, Page, or Group.

• For OLE controls, Rows can be All, Current Row, Page, or Group. The

available choices depend on the layer the control occupies.

Not in validation rules or filter expressions

You cannot use this or other aggregate functions in validation rules or filter

expressions.

Using an aggregate function cancels the effect of setting Retrieve Rows As

Needed in the painter. To do the aggregation, a report always retrieves all rows.

Examples This expression returns the first value in column 3 on the page:

First(#3 for page)

This expression returns the first distinct value in the column named dept_id in

group 2:

First(dept_id for group 2 DISTINCT)

This expression returns the first value in the column named dept_id in group 2:

First(dept_id for group 2)
