Crystal Reports V10 returns 'Not supported' error message
I have a client installation using Crystal Reports v10 SP6 reporting sales and volume figures daily/weekly and monthly year on year comparisons for more than 100 stores.
They have just upgraded the MSSQL 2000 database to MSSQL 2008 and the daily report fails with a 'Not supported' error message, on the larger brand of stores, but not on the much smaller brand of stores.
I'm trying to find out if is there a known condition in MSSQL Server 2008 Express Edition which trips up Crystal Reports Version 10 on large volumes of transactions. (60 million or more rows)
All help is appreciated
