Question

我在MS报告服务中有一个报告，可以在屏幕上呈现良好状态（通过报告服务Web界面查看报告时），但是当我将其导出为PDF时，它会出错。

尝试通过Web服务访问报表时会显示以下YSOD，但报表服务Web界面中呈现为PDF时报表也会出错。

关于如何追踪导致此问题的原因的任何想法？

修改

看起来当报告非常大（不确定阈值是多少）时，PDF无法呈现。（40多个PDF页面使其成为错误但不是5或更少）。

Answer 1

尝试查看呈现报告的服务器上的错误日志可能是个好主意。看看RS是否有特定的事情发生。您可以从Visual Studio本地生成报告到PDF吗？

如果实际超时，我之前就已经看到了类似的行为。该报告是否需要花费一些时间来制作？那么导出到其他格式呢？
