The GetSummary function has the effect of a summary field in a
subsummary or grand summary part, performed from within a
calculation. To calculate a subsummary value, you must sort by the
break field to get appropriate results in a GetSummary function.
Use GetSummary to:
1 create subsummary or grand summary values without using
subsummary or grand summary parts on a layout—you can see the
resulting values in the body part
1 perform mathematical calculations on a summary field
The following examples show the result of the GetSummary function. In
the first example, the file is sorted by the Department field first, and then
by the Last Name field. Department Subtotal is a calculation field:
GetSummary(Total Number, Department)
Break field
Summary field for subsummary
Summary field for grand
