error in refresh report
I have a qurey. if I am refreshing a report , and in the midst of it an administrator starts processing a dimension , or runs optimisation, then my report gets interrupted and throws an error "EVDRE encountered an error retreving data from web server"
I would like to understand the following :
1. How to avoid this kind of error .
2. Even if I get this error ,what happens after the process of dimension or optimisation that the aministrator is running is completely finished ? will the report automatically start refreshing or do we have to close the report and open it again and start refreshing after the admin tasks are competely over ?
3.This become a serious issue when I put heavy files on refresh ,overnight.then if something gets interrupted at night ,then report has to be closed and I have to put it on refresh in the morning again . this is a real pain and a sheer waste of time .
Please let me know what generally happens next ? kindly help .
