| Hi all
SQL 2008 R2 Report Builder
I'll keep this simple.
Imagine I have a dataset that relates to sales.
The data set at row level has a year and month.
In the report I group by year and month.
At the year level I have an expression which shows the average sales per month for the year. An expression which sums up total sales for the year divided by distinct count of amount of months there are the in current dataset SUM(sales)/DISTINCT COUNT of Months.
This works fine.
I've now been asked at year level for an average of the last 6 months. So if we had say 11 months details at month level Jan - Nov then at Year level there would be an average of Jan - Jun sales.
Any idea on how to do this? The requesters come from Excel and they say it is easy lol, select Jan - Jun date range and choose AVG in the sum area.
