This article applies to a Microsoft Access database (.mdb) and to a Microsoft Access project (.adp).
This article demonstrates how you can use a total from a subreport on a main report, and how you can display a total for all the subreports.
If you use an expression similar to
=Sum([MySubReport].Report![Product Sales])on a main report to sum a reference to a subreport control that contains a subtotal, you receive a
error message. This error message occurs because the Sum() function (and the other aggregate functions) can reference only fields, not controls. To avoid this error, place the sum expression in the subreport's report footer, and then reference that expression in the main report.
Displaying the Total from a Subreport on a Main ReportCAUTION: If you follow the steps in this example, you modify the sample Access project NorthwindCS.adp. You may want to back up the NorthwindCS.adp file and follow these steps on a copy of the project.
To display the total from a subreport on a main report, follow these steps.
Displaying a Total for All SubreportsTo display a grand total for all subreports, you can use either a second subreport or a control's RunningSum property.
Using a Second SubreportYou can use a second subreport to display a grand total. When you add a second subreport to a group footer section, make sure to link the subreport to the grouped field so that the subreport displays the total for that group. If you place the subreport in the report footer section, do not link the subreport to the grouped field so that the subreport displays a total for all the records.
The following example demonstrates how to use a second subreport to display a grand total on a main report:
