Can negative cost values be added in Project Server? RRS feed

  • Question

  • We are being asked by a user to add a negative cost value to reduce the total value of the project after the project has been closed. We are a support team to resolve issues - not to provide specific coding or custom fields to the tool without a major corporate process initiative to do so.

    Our assumption is that a negative value can not be added to a standard cost field without impacting the associated reports in a way that throws a ###, NULL, or #VALUE# error. Is this a correct assumption?

    Has anybody tried using a negative value? If so, what were your results?

  • Hi Watson,

    Negative cost cannot be entered for cost resources. That being said, you can enter negative costs for the fixed cost field or all the cost custom fields.

    What I suggest would be to use one of the cost 1 to 10 custom fields renaming it as "cost adjustment" for instance and enter a negative cost. Then you could use it or not in your reports depending if you are willing or not to include this adjustement in the total project cost.

    Please note that if you want to negative cost to directly reduce your project cost, you might use the fixed cost field.

    Hope this helps,
