Problem when display report
I am trying to show report on Crystal Reports Server 2008 using Crystal Report Viewer (version: Crystal Report XI). This report extracts data from a table in SQL Server 2000. But when Report Viewer is opening this report, it displays 2 error messages, one by one, before display report:
- The first: "Information is needed before this report can be processed".
- The second: "Object reference not set to and instance of an object".
I do not know why, please help me to avoid them.
