Adding Group Computations to a Report Recipe
Users want a report that allows them to perform calculations between different fields in a grouping report. This allows for complex metrics on the grouped items in the report.
Add group computation tags to a grouping report recipe to perform computations between different item fields. Group computations are applied to multiple fields in a group of items.
For example:
<%version 1%>
<%description <b>Description: </b>This is a report that uses
Windchill RVS group compute report tags.<br><br>%>
<%param name="reporttitle" type="String" prompt="Report Title"
value="" description="Descriptive title for your report."%>
<%param name="reportheader" type="MultiString" prompt="Report
Header" value="" description="Text appearing at the top of the
report page."%>
<%param name="reportfooter" type="MultiString" prompt="Report
Footer" value="Confidential - Internal Use Only"
description="Text appearing at the bottom of the report page."%>
<%param name="groupcomputeheading" type="String" prompt="Group
Compute Heading" value="Group Metrics" description="This is
displayed at the top of the group compute area."%>
