Why are burden cost amounts in the Burden Details window different from those on the resource assignment?

The burden cost amounts are calculated based on the latest built burden schedule version. If the burden rates on a resource assignment are not refreshed on the project plan, budget, and forecast, then the burden cost amounts may not match.

The burden cost amounts in the Burden Cost Details window is calculated using a single transaction date, therefore a single burden schedule version. When a resource assignment spans multiple periods, there is a chance that the individual period start dates reside within multiple burden schedule versions. When viewing burden cost details for a resource assignment, the resource assignment start date is used to determine the burden schedule version, therefore the burden cost amounts may mismatch with the resource assignment burden cost amounts. This is due to the actual burden cost of the resource assignment being an aggregate of the individual periods, which may have used different multipliers.
