Recently we did a couple of Project Server/Online Implementation based projects which involved customization’s like Demand Management Workflow, Document Approval workflow, Issue or Risk Escalation workflow and much more. During these customization’s, we were posed with a challenge on updating the complete percentage of project tasks using the project server workflow of the project to submit an event.

We assumed that there should be an easy solution using SharePoint designer workflow and it should not take much time to implement. But later, we realized that project tasks could not be updated in the same way in which project-level field can be.
