Hello,

I have a reporting services report that groups by business unit. The report
has 7 columns. One of the columns uses the COUNT function. If I run the
report for 1 business unit, I get about 14000 records. These records
collapse to 1 row when I click the business unit drill down. The process of
exporting this report to Excel, from clicking the Export button in SSRS to
when I can get a response from the cursor in Excel file, takes like 5
minutes. In Excel, when I expand or collapse the subtotal (my business unit
group from SSRS) the response time is very long and it kind of renders other
applications (Outlook, etc.) useless until the expand or collapse is
finished. If I run the stored procedure for the report in Management Studio
and just paste the result set into Excel, there's no problem - the file
responds very fast. Is this a well-known issue and are there any fixes for
it? This problem basically makes the report impratical for users. We have
SSRS 2005 (version 9.00.1406.00) installed.
