DCAA ISSUE: DEC. 8, 2015. As a result of Section 893 of Public Law 114-92, which prohibits the Defense Contract Audit Agency (DCAA) from providing contract audit support to NASA, DCAA is no longer reviewing cost type contract vouchers for NASA. Thus, there is a need to slightly modify the process for vendors to submit vouchers for review and payment. Please contact your Contracting Officer for specific instructions; DO NOT submit hardcopy vouchers to the NASA Shared Services.
Note: As a result of this new public law, the DCAA DoDAACs (Department of Defense Activity Address Codes) and the DoDAAC for the NASA Center has to be changed in order to route for proper review/approval by Center Procurement. The DoDAAC for the NSSC Paying Office will not change.

Wide Area Workflow (WAWF) is not to be used for the submission of fee vouchers.
NASA Implements E-Invoicing Phase IA:
Effective March 31, 2014, NASA implemented e-Invoicing Phase IA and will expand the scope to include all cost type contracts as required by the Department of Defense Federal Acquisition Regulations System (DFARS) change of August 29, 2012. NASA Headquarters Procurement issued Procurement Information Circular (PIC) 14-02 to implement Wide Area Workflow (WAWF) on all cost type contracts to Center Procurement Policy Offices.
The class deviation will provide authority to deviate from the auditor receipt of voucher requirements at NASA FAR Supplement (NFS) 1842.803(b)(1)(D). This class deviation will implement the revised Defense Contract Audit Agency (DCAA) policy and procedures for the submission and pre-payment processing of contractor interim vouchers as delineated in DFARS 242.803 (b) (B) entitled "Disallowing costs after incurrence, auditor receipt of voucher," dated August 29, 2012.
