Correlation bug in pertmaster
- 1. Issue due to correlating a big number of activities in Pertmaster (Primavera Risk Analysis) Issue Description The uncertainty for my project has common cause, it is a financial issue, so I made correlation for more than 8000 activities which will be affected by this issue, after I have applied templated quick risk with correlationand saved the file the size of file increased from 60 MB to 1.7 GB causing hang to the program. Even when I tried to correlate these activities into groups every group does not increase than 2000 activities I got the same result. Work around solution I made using risk factors instead of uncertainty, each risk factor assigned to 2000 activities, the program hang up. Operating System Microsoft Windows x64 (64-bit) OS Version 8.1 Primavera Risk Analysis version 8.7.0076 (including update Patch file SP8) Oracle Support Team I shared this issue with Oracle SupportTeam and they investigate it and classify as “Severity 2- significant”. They replied me “this fix would require a major codechange as the current algorithm used to model correlation is running out of memory when running the scenarios in your plans. “ Oracle workaround To create new tasks to represent groups of tasks. So say for example you have 3000 tasks that represent engineering and you want to correlate their risk. Create a single task using the earliest start date of this group of activities for the Start and the latest finish of this group of activities as Finish. You can then apply risk to this task and correlate to other tasks if needed. Just I wanted to share this information with you, Some Risk Analysis Programs don’t include “correlation” option But I think that any software has limitation and bugs and it is very necessary for any professional to identify them and find a workaround.
