MFGF,
Thanks for your response.
One strange thing is that , I had developed earlier a report ABC (detail) with burst options and it works perfectly fine.This is a new report (SUMMARY, the one with stuck status) is based on the same package as the ABC , just the layout is different,and we are facing this issue.
We are planning to restart Cognos services and see if it makes any difference. If not, then will log a case with the support team.
Also what happens, if we just leave it as it is? Anyway, the report is bursting and e-mails are sent and received. Also I can run the report multiple times, so can it just be left as it is..?
If anyone who has faced this issue, can pass on the information on how they solved it, it would be of a great help.
