Table 13.   Reason codes associated with step "PREPACQC", program code 007 (last revised 9/25/2008). 
 

KEY:
     IN "R.CODE" COLUMN:

                                           B - OCCURS IN ALL OPERATIONAL VERSIONS OF PREPACQC EXCEPT RUC (THE PREPACQC STEP DOES NOT RUN IN THE RUC NETWORK).
                                           E - OCCURS ONLY IN NAM/NDAS VERSION OF PREPACQC. 
                                           N - CURRENTLY DOES NOT OCCUR IN ANY OPERATIONAL VERSION OF PREPACQC.
