When browsing a cube using Excel 2007, you can drillthrough the measures to display up to 1000 rows of the transaction level source data.
I often get asked whether this limit of 1000 rows is configurable – well the good news is yes it is.
There is an option in the actions tab of the BIDS cube designer which allows you to specify the maximum rows, but helpfully this is ignored by Excel. Instead, you have to set it in Excel when you create a pivot.
Just click “Options” on the “PivotTable Tools” ribon, then in the “Change Data Source” dropdown click on “Connection Properties“. In this screen, just change the “Maximum number of records to retrieve” property.
