從Reporting Services呈現到PDF時發生錯誤

Question

我在MS報告服務中有一個報告，它可以很好地顯示在屏幕上（通過報告服務Web界面查看報告時），但是當我將它導出到PDF錯誤。

嘗試通過Web服務訪問報告時顯示以下YSOD，但報告服務Web界面呈現爲PDF時報告錯誤。

關於如何追蹤導致此問題的任何想法？

它看起來當報告是非常大的（不知道的門檻是什麼）像那麼PDF無法呈現。 （例如，40頁以上的PDF頁面出現錯誤，但不是5頁或更少）。

嘗試查看呈現報表的服務器上的錯誤日誌可能是個好主意。看看RS是否有特定的事情發生。你能從Visual Studio本地生成PDF報告嗎？

我以前見過類似的行爲，如果它實際上超時。該報告是否需要一些時間才能生成？那麼導出爲其他格式呢？
