SharePoint (and Project Server) Shenanigans

Due to possible differences in calendars between EPM (Enterprise Calendars) and Microsoft Project (local project settings), resource rate changes using an effective from date may not be applied from the beginning of the working day. At one client in particular, where all resources in the Enterprise Resource Pool received an updated (increased) rate from the first of the financial year, this caused project financial information to be out by a couple of hundred to a few thousand pounds. Given that this particular client uses timesheet and therefore project actual work and cost figures to update their financial system for client billing, this is quite a big problem.
This article describes how to set the effective from time for the resource rate in order to ensure that it is applied from the beginning of the working day.

Setting Project Options
Open Microsoft Project and click on File > Options. Under the General tab, change the Date format to include the time, as below, and then click OK.

Updating resources
For resources that require a rate change, navigate to Resource Center in PWA. Select the resources for which the rates should be updated and click Open:

This will open the selected resources in Microsoft Project. To update the resource rate, double click on the resource and click on the Costs tab. The Effective Date will contain the time as well as the date. Ensure that the time is set to the same as the Enterprise Calendar for the start of the day.

Repeat for all resources as required. When complete, save the changes to enterprise resources (File > Save) and close  Microsoft Project.
If required, change the date display setting back to show only the date by repeating the steps above.
