hello everyone,
We are upgrading from BPC 7.5 to BPC 10.0 and are in the process of converting all the 7.5 reports to 10.0 and i'm having a problem with a large report.
We are on BPC 10.0 SP 17 for the Microsoft platform and we are on the EPM Add-in 10.0 SP22, we also use excel 2013.
The report in question consists of ~65,000 rows of data. Basically, the row axis is running 8 different accounts by 630 Entity members by 13 different time members. Many of the rows contain empty or blank data, but they are needed for other calculations in the report, so remove blank/empty rows is not an option. For testing purposes i have created the report without any calculations to see how performance is impacted.
What I've found is that the initial report create time is ~ 25 seconds, however, if i change a member of the time dimension then refresh, the report takes ~10 minutes to refresh. The 7.5 version refreshed in ~ 1 minute consistently.
After enabling logging for the EPM add-in it appears the overhead is related to clearing the old dataset perhaps? these are the logging entries for the second refresh i see:

I'm not sure where to go to next to try to optimize the performance on the subsequent refreshes. If anybody has any advice it would be much appreciated.
Thank you!
