why is system creating accounting entries for burden cost

Summary:

We have not included few expenditure types in the Burden Structure. When raw cost is booked on transactions with these expenditure types, burden cost is not calculated. However, we notice that the system is still trying to create an accounting entry for burden cost (equal to raw cost). This accounting entry is not required and should not be sent to GL. Accounting entry for raw cost should only be generated and sent to GL from Projects.

Is there a way to stop the system from creating accounting entries for burden cost even if there was no burden cost calculated on the expenditure?
