Correcting and Cancelling a "Calculated" Execution Report

Imported from previous forum

[ original email was from Vinay Gaur - vinay.gaur@ubsw.com ]
Should ExecTransType of Correct/Cancel be used only to correct/cancel fills? Or, can we also use ExecTransType = Correct/Cancel to correct/cancel "Calculated" Execution Reports?

Thanks in advance
