WAWF / PIEE guide
Treat rejection messages as control signals
The message usually points to one of four evidence chains: contract data, receiving evidence, routing, or invoice value.
Routing
Validate DoDAACs, roles and document type against the controlled contract setup.
Receiving evidence
Match quantities, acceptance and receiving-report status before presenting an invoice as ready.
Contract-line reconciliation
Trace billed quantities and amounts to the applicable CLIN, funding and prior billing state.
Operational boundary: This guide explains a controlled workflow. Contract terms, permits, portal instructions and official decisions remain authoritative.
