PPS-N Version 2.0: This effort will focus on constructing functionality to update the local copy of the NDF VistA files using the PPS-N data eliminating the need for NDFMS to include the patches. The new functionality will eliminate the need to update the national NDF files, increase the timeliness of the local copy of the NDF Vista files, and increase the efficiency of the NDF/local drug file (#50) matching process. In addition, this effort will correct anomalies, defects, and user interface issues which are critical or require minimal effort to fix.
