Hi, I have a data table with 46000 rows and I want to monitor these using my rptdesign. This rptdesign has css style sheets and a script that substrings every row . However, BIRT is very slow and make me wait in the state of "Processing, please wait" and does not be able to monitor it. But there is not a error message or something else. For smaller queries like 100 rows, there seems no problem and monitors. Advice me, where can be the problem? Is it about style sheets or script?
