Hi Experts,

When I use the export function to dowload report for PDF format from BIEE Analytics , and it will generate the following error message,so I do not know what happen. Please help me to solve this odd problem. Thanks.
By the way , if I try to drop some columns(retain 10 columns ) and export report for PDF, it will be OK. However, if I add any one more column , it will not work. So I think it is the configuration problem, but I do not know how to do it. Please give me the suggestion. Thanks
PS:
1. When I export the same report for  Excel (2003 or 2007+) format, it will be OK.
2. When I use agent to send this report for PDF, it will also be error.
3. The report involves 906 rows and 26 columns.
4. For more detail information, you can view the attachment.
