Summary:

Is it possible to derive the cost center for project revenue from the project task in the SLA instead of the project header?

Content (please ensure you mask any confidential information):

We re-org annually and do not want to re-post all the costs to the new org which happens when we change the project header org. Can we pull the project task org instead to derive the cost center in the revenue distribution?
