Slow performance for Excel-link reports when using 'automatic' calculation, when using Excel 2013 or later

Troubleshooting


Problem

User clicks F9 to run/refresh an Excel-link report. This takes a long time (or may actually appear to never finish).

Symptom

Main symptom

Slow performance when running Excel link reports.

Secondary symptom

In some circumstances, it has been seen that (sometimes - intermittently) Controller goes into a 'loop'.

  • Specifically, it re-runs "Analysing Sheet" for a second time.
  • In fact, this 'Analyzing Sheet' message may never disappear (it may stay on the screen forever / constantly).
