SYMPTOM
Users may see the following error when executing an Enterprise Manager report or document in 3-tier in Strategy 9.3.1 and newer releases.
Error: SQL Generation Complete The job execution time limit set in Strategy Intelligence Server has been exceeded for job ###: at (###). The job was cancelled.

Since job prioritizations do not affect 2-tier connections, the issue is not seen in 2-tier. The timeout setting is due to the “Interactive reports” governing limit at the project level.
ACTION
The user can either modify the job prioritization settings of the default Statistics database instance OR the user can create a new database instance to the Statistics repository, which will have 2 connections set for each job priority.
