Hi Jimmy,
have a look to the data elements
DPR_TV_CHECKLIST_ITEM_NOK
DPR_TV_CHECKLIST_ITEM_OK
DPR_TV_NOT_RELEVANT
I think you have to modify them, to get changed descriptions. As Ravi said, there are to much dependencies to have other result values (e.g. convertion in cl_dpr_api_services=>convert_cit_result_to_attr)
