different totals in timephased and non-timephased data sources RRS feed

  • Question

  • We recently experience data inconsistencies in MS Project Server 2010 database between timephased and non-timephased data sources: a task (with duration of several months) is assigned a material resource. Cost, let's say 100000€, for that material resource is entered using Prof. client.

    Now MS Project distributes the cost to single periods/days. But comparing total cost in timephased and non-timephased data sources for that task show different results: timephased reports only lists 96354€ for this task (e.g. Portfolio Analyzer cube or MSP_EpmAssignmentByDay table). There were no fxed cost entered, no cost per use etc. And we're just looking at 'Cost' field. Any idea what's going wrong here?

  • I believe the latest Cumulative Update listed a hotfix for this behavior. I don't have the link handy but you should do a search for the August 2012 CU.

  • Hi Tale,

    I continued my tests to reproduce the issue and found that calendar assignments on project level influence distribution of material costs for timephased cubes/tables. Let me describe the situation in detail:

    1. The project is assigned a calendar that includes local bank holidays as non-working days. A material is defined as resource for a task in a week with a local bank holiday. overall cost (entered for that material in that week and that task) is 6k€. MSP Prof. 2010 client displays 6k€ cost in any view (especially on Task Usage view on per day basis).

    2. Table MSP_EpmAssignmentByDay, however, simply reports cost for 4 days, i.e. 4.8k€.

    Any idea, if this behavior is a known "constraint"?

    Kind regards

  • We've found it best to not mix work and cost resources on the same tasks due to oddities like this. As material resources can't have a calendar, this would seem to be a bug, as the cost should match the amount for the duration of the task. 

    If you separate the tasks out into a material task and a work task, do you see the same behavior?

  • Mixing material and work resources is of no relevance in this case. The only thing that counts is the project calendar (I've not tested yet, if other calendars play a similar role)
