Bypassing the calculation errors of Project Server 2007 (pre-sp1)

The problem:
When adding non-working time in a resource’s calendar, in Project Server 2007, you may experience data inconsistencies between submitted actual work, using MS Project server PWA, and actual values in MS Project 2007 after opening the specific project. It looks like the application has problems calculating actual work and non working time in parallel. A common example is when submitting a timesheet with actual work and sick time together (non-working by default) and importing this timesheet into my tasks view.

A way to bypass the problem:
Before accepting actual work updates from your team members, open the project, save it, publish it and check it in. Then accept actual work from your team members and repeat the save and publish procedure. Using this method you are updating the project with the resources calendars before updating actual work, avoiding that way the calculation errors.
