What the documents look like
Export tax rebate filing matches tax vouchers after goods have left the country. The work draws on the electronic tax bureau, the export rebate filing system, customs electronic information and the finance ledger. Day-to-day documents include the export tax exemption and rebate filing form, the export customs declaration, purchase invoices and foreign exchange receipt vouchers. Compared with export customs declaration, rebate filing performs voucher matching after export, so material status and authorization status frequently sit at different points. Handover management deals with that gap: a customs declaration may already show export while the matching purchase invoice is still moving through authentication, and the foreign exchange receipt voucher may cover only part of the declared amount. Workflow routing connects interaction nodes with downstream processing nodes so that materials, actions and requests each rest in a state that can be checked, and so that a retrieval result or a form submission is not treated as completed authorization.
Constraints at the workflow routing step
The form input node is a user interaction node. When it triggers, the conversation enters an interaction state, the workflow state is recorded, and after the user completes the required information and submits, the node collects the submitted values and passes them to later nodes. The user selection node is also a user interaction node: it enters the interaction state, records the workflow state, and when the user makes a choice the node evaluates that choice and executes the corresponding "yes" branch. The interaction state is behavior of the interaction node itself; no separate global state-recording switch is documented. Collected information must be passed explicitly to subsequent retrieval, judgment or interface nodes, and outputs must be compared against inputs item by item. Order writing, document backfill and external status synchronization require a separate business interface or a later process. The form collects values only.
Hypothetical paper exercise sample: a finance staff member at a foreign trade enterprise submits a request during rebate filing handover. The material text reads: "Export customs declaration number A-001, export date 12 March 2024, corresponding purchase invoice number B-002, invoice status authenticated; foreign exchange receipt voucher C-003 shows a receipt amount equal to 60% of the declared amount, receipt date 2 April 2024." The draft sentence to be judged reads: "The rebate filing materials for this export batch are complete and ready for submission." The fields needed for judgment are the same customs declaration number, the invoice status and receipt ratio for the same filing period. The material does not state the filing period or the arrangement for the remaining receipt; both remain unsupported.
Configuration and implementation checks
| Configuration item | Type | Description |
|---|---|---|
| Form input node | Interaction node | Enters the interaction state on trigger, collects required information, passes it to later nodes after submission |
| User selection node | Interaction node | Executes the corresponding "yes" branch after the user makes a choice; verify each branch connection |
| Output handoff check | Implementation check | Pass collected information explicitly to later retrieval, judgment or interface nodes; compare outputs against inputs item by item |
| External action division | Implementation check | Order writing, document backfill and external status synchronization connect to a separate business interface or later process |
| Retrieval scope check | Implementation check | Check the vector model identifier, exclude libraries from a different model, record actual observations |
| Empty result handoff | Implementation check | Use the paper input [] to check downstream design; do not claim that a fictional rule retrieval necessarily returns [] |
Three common errors
- Treating form submission as completed authorization. In the sample, the draft sentence says the materials are complete and ready for submission. The form collects values only; filing submission and rebate review are downstream business actions that need a separate interface or process, and the submission action itself does not create an authorization state.
- Treating a retrieval hit as a permission filter. A relevance score is not a category, entity or permission filter, and retrieval does not perform authorization judgment. Libraries from different vector models cannot be associated together; check the identifier and exclude non-matching libraries rather than running a cross-model retrieval to compare missed recalls.
- Treating a pending item as a negative finding. The sample does not state the filing period or the remaining receipt arrangement; this is unsupported, and it cannot be written as a material conflict or as missing filing permission. A pending review does not show that operating permission is absent, and a quotation validity period does not indicate a supply period.
How to verify the setup
- Input the sample material text and the draft sentence. Compare "complete" in the draft sentence against the invoice status and the 60% receipt ratio stated in the source, and against the filing period that is not stated. Observe whether a conclusion appears that goes beyond the source text. The condition is satisfied if the draft sentence keeps the unsupported fields as unsupported.
- Input the sample material text and the user selection branch. Compare the selection result against the "yes" branch connection and observe whether the branch executes according to the selection. The condition is satisfied if the branch connection matches the selection.
- Input the paper empty result [] and the downstream handoff design. Compare whether the downstream design has an explicit handling path for an empty result, and observe whether an assertion appears that a fictional rule retrieval necessarily returns []. The condition is satisfied if the downstream design retains an empty-result branch.
This page addresses one scope only: export tax rebate filing, operations permission and handover management, workflow routing. During operations handover, the authorization state of each material, action and request must be identified, and retrieval or form submission must not be treated as executed authorization.
