Hi, Used SSRS 2008 and a Table Report. I'm having 1 Group and Details. After creating a parent group with header and footer, then deleted the Row Group Column that (coz i don't to want consume the Vertical place, so used a field on top of Detail section to show the group field name). Now once i delete the Row Group Column, i can not able to use "Document Map" for that group. The error i'm getting "An error occured during client rendering. Index was outside the bounds of the array" Please suggest. Hope the problem is clear Thanks

Hi, This error is caused by the local data cache (.rdl.data) file. So, please close Business Intelligence Development Studio (BIDS) and delete the appropriate .rdl.data file for the dataset. Then open BIDS and run the report again. This recreates the cached data with the appropriate index bounds.
