What transaction identification code (TRIC) is not an option for processing after disposition instructions for an unserviceable asset have been received?

The transaction identification code (TRIC) that is not an option for processing after disposition instructions for an unserviceable asset have been received is ISU. This code is utilized primarily for initiating the transfer of unserviceable property to a maintenance facility for repair or overhaul, not for processing disposition actions.

In contrast, the other TRICs listed play roles in the disposition process. TRD is used to indicate that the asset is being disposed of according to the instructions received. RDD is involved in the scheduled disposal of unserviceable items and can be used to record the action taken after the disposition instruction has been issued. AFD is used for reporting the administrative actions related to the disposal of unserviceable assets. Thus, while ISU is an essential code for repair processing, it does not align with the activities performed after the instructions for definitive disposal have been received.
