Access Subreport with TOP clause

I have a report with a subreport that uses TOP 1 clause in the query but it is not displaying the subreport when I use TOP 1.

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

If I remove the TOP clause the records DO show up using the same key.
I tested the query alone with the specific key and it works, even the report alone, but not when using the Top clause as a subreport.

How is your report configured?  Is your subreport linked (Master/Child) to the parent report?  If so, an you use the Top 1 syntax in the query, you will only see the entry in the sub-report for that record in the main report that corresponds to the record in the subreport.

You might want to change the query of the subreport to something like:

SELECT [GroupID], [Field1], [Field2]
FROM SomeTable as T
WHERE [Field1] = (SELECT MAX([Field1]) FROM SomeTable WHERE [ID] = T.ID)
GROUP BY GroupID

Assuming that the [GroupID] field is used in the main report, this query would return one record (with all the appropriate fields) for each [GroupID] value.  Then use the [GroupID] field in your master/child relationship and you will have your main report and a single record for each matching GroupID in the subreport.

IT Pros Agree: AI and Machine Learning Key

We’d all like to think our company’s data is well protected, but when you ask IT professionals they admit the data probably is not as safe as it could be.

Top 1 for a seubreport will use only 1 record from the underlying recordsource. So I expect your report to not show any record, or that only one record selected using Top 1.

Change top 1 to top 100 and check!

To display top record for each subreport, add a text box to the detail section of the subreport, say txtX
Control SOurce=1
Running Sum: Over All
Visible: No

Remove the top 1, and sort properly.
Detail_Format event:
Private Sub Detail_Format(Cancel As Integer, FormatCount As Integer)
    If txtX > 1 Then
        Cancel = True
    End If
End Sub

Try this:

' No page footer on page 1
Private Sub PageFooterSection_Format(Cancel As Integer, FormatCount As Integer)
    If Page = 1 Then
        If Page = pages Then
        Else
          Cancel = True
        End If
    End If
End Sub

' No report footer and increase size of page footer
Private Sub ReportFooter_Format(Cancel As Integer, FormatCount As Integer)
    PageFooterSection.Height = PageFooterSection.Height + 3000  '(adjust to your needs-do some homework)
    Cancel = True
 End Sub
