    Posted: 17 Mar 2011 at 3:58am
Recently I was reading about the passes that CR goes through when it generates the report and remember we get a lot of questions related to "summaries in the header"

Intuitively I would say "well it hasn't read the records yet so you shouldn't expect much" but then recently I tried actually creating a summary and placing it in the header and it was displaying the correct results.

How does that work? It seems like summaries work differently from running totals although one could achieve similar results through both methods.

Is it then possible to replicate summaries using formulas and have them function the same way? (ie: place it in the header and it will be correct)

it all depends on what you are trying to do. In some cases you can mimic a running total with a formula and a summary function to get a value for a header and sometimes not. Usually depends on duplication of data.
Use gender counts for example.
If the list is unduplicated then you can use 2 formulas for the
 if -male-then 1 else 0 and do a sum and be fine.
if there are duplicate rows you are out of luck.
You could use a crosstab though.
