I have recently installed Crystal Reports Server 2008 and applied all updates to SP2. When I schedule reports and use the format of "Excel (Data Only)" they fail with the following message:
Error in File ~tmp616064274adcfe8.rpt: Operation not yet implemented.
I am able to export reports to any other format without problems (Excel, Word, PDF, text, etc...). This error only occurs with "Excel (Data Only)" format.
Thanks in advance!
