What the data for this category looks like
Refined petroleum product sales declaration and case file data primarily comes from gas station POS transaction systems, oil product purchase ledgers, inventory check reports, and internal approval circulation documents. Data update frequency aligns with business nodes. Individual sales transactions generate corresponding case entries in real time. Monthly summary declaration materials are updated at the end of each month. Each case file document includes structured fields such as transaction serial number, oil product grade, sales volume (liters/ton), unit price, payment voucher number, and approval node records. Some approval materials include scanned signed vouchers. Field units uniformly follow metrology specifications for the petroleum and petrochemical industry.
Constraints imposed by these characteristics on citation source and traceability
Individual sales transactions generate dense case entries in real time. The citation traceability link must limit the recall time window and business scenarios, to prevent irrelevant data from interfering with context. Some approval case files include scanned signed vouchers. Traceability must support associative traceability between OCR-recognized text and structured transaction fields, to ensure cited content matches original vouchers one-to-one. Monthly summary declaration materials include multiple cross-cycle documents. Traceability must support parallel recall of multiple files and cross-document data association. Unified metrology field units in the petroleum and petrochemical industry require the traceability link to automatically match units, to prevent citation deviations caused by unit conversion.
How to set up the configuration
Reference only; verify against the target FastGPT release and deployment documentation.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
| Maximum Context | 800–1200 characters | Adapts to the average length of individual refined petroleum product sales case files, to avoid context overflow |
quoteMaxToken | 1500–2000 tokens | Matches the total length of structured fields and text content in petroleum and petrochemical industry case files |
| Recall Limit | Top 8 entries | Controls the number of returned entries for individual transaction traceability, to avoid redundant information interfering with review |
responseData | Return only structured fields and corresponding file paths | Ensures traceability results only contain valid citation information, to simplify review logic |
detail | Enable full traceability | Retains OCR text from scanned vouchers and original file associations, to meet compliance requirements for case file review |
| Timeout Threshold | 60 seconds | Adapts to processing duration for batch traceability of multiple documents, to avoid timeout interruptions |
Three common errors
- Phenomenon: A
quote type erroris thrown during invocation, and the interface prompts that the input variable format is abnormal. Cause: Reference variables are not configured per the structured field format of petroleum and petrochemical industry case files, and non-standard field names or unit parameters are used. - Phenomenon: Batch traceability results do not include corresponding file names, only text content is displayed. Cause: The
responseDataconfiguration item is not enabled correctly, and the return file path field is not specified. - Phenomenon: Citation content returned by the large model does not match the original case files, and incorrect cross-transaction associations occur. Cause: The recall time window and business scenarios are not limited, and irrelevant sales case entries are recalled.
How to verify proper configuration
- Upload a single refined petroleum product sales transaction case file, trigger the citation traceability process, and verify that the returned results include preset structured fields and file association information.
- Batch upload monthly summary declaration materials, and confirm that traceability results automatically filter out irrelevant case entries outside the target business scope.
- Call the API interface, and check that the returned citation data includes specified file names and corresponding content.
- Input abnormally formatted reference variables, and verify that a
quote type erroris thrown, confirming that the configuration item's verification logic is active.
