Question

Ho un rapporto in MS di Reporting Services che rende bene allo schermo (quando si visualizza il report tramite l'interfaccia web di servizi di segnalazione), ma quando vado ad esportare che ad un PDF esso errori.

Il seguente YSOD viene visualizzato quando si tenta di accedere al report via web services, ma gli errori di report per il rendering in PDF dall'interfaccia web di servizi di segnalazione pure.

Modifica

sembra che quando il rapporto molto grande (non so cosa la soglia è) è quindi il PDF non riesce a rendere. (40+ pagine PDF rende errore, ma non 5 o meno, per esempio).

Answer 1

Può essere una buona idea per cercare e guardare i registri degli errori sul server che rende il rapporto. Guardare per vedere se c'è qualcosa di specifico che si verificano con RS. Si può produrre il rapporto localmente da Visual Studio in un file PDF?

Ho visto un comportamento simile prima, se esso è in realtà timeout. Se questo rapporto prendere un po 'di tempo per produrre? Che dire di esportazione in altri formati?
