How can I summarize data across all records in a report?

Question

I have a report with section footers summarizing a count of data items in each section. I'd also like an overall footer with a count of all items on the entire report.

I'm currently using

 count([Value] for [Grouped Value])

This is how I can get aggregate function information for grouped sections but it doesn't seem to work in the overall footer; it outputs the count of items in the last group, not all items in the report.

How can I summarize/aggregate information for a whole report in Cognos?

Answer 1

The expression you need for the data item in the overall footer to get full-report summary information is for report:

 count([Value] for report)

If you're using Cognos 8 the for report component is already in the Data Item Expression list under Components:

I figured this out from Cognos Summary Functions.
