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.
