How can we avoid 'No data fetch"

We have couple of report which are having around 10 data providers. The report is consuming more than 20 minutes to complete refresh due to huge amont of data But some of the data provides does not fetch data at that time user is getting prompt saying 'No data to fetch' until we click on ok it will not running further. Due to this the person has to watch the report until it complete refresh which is conuming lot of effort

Could some one suggest me how can we avoid that 'No data fetch" so that the report will refresh completely even if any dataprovider not fetching data.

Thanks in advance

Just a curiosity, have you tried writing macro for this?
