CHARM Process Type in AIC_CM_TRANS_CR component

Does anyone know how to get the Process Type field ( holds Normal Change/Admin Change/RfC value) while inside the AIC_CM_TRANS_CR component class ZL_AIC_CM_T_TRANSPORTREQP_CN05? I have enhanced the AIC_CM_TRANS_CR/TransportReqPage1 view and redefined the GET_CHKB_REQ_TYPE_CUST ( the checkbox on the transport create screen for workbench or customizing ) .

In the class CL_AIC_CMCD_BTPARTNERSET_CN this is how you get it, iv_process_type = me->mo_view_controller->get_process_type( ), but that won't work in CL_AIC_CM_T_TRANSPORTREQP_CN05.

Any ideas?

Thanks for any help.
