What the data for this category looks like
Data sources for packaging and printing intelligent due diligence reports include order sheets exported from internal enterprise printing production ERP, material requisition details, quality inspection reports, and supply settlement documents from upstream paper material suppliers. Update frequency varies by business type. Production order data updates in real time with printing batches. Material ledgers update weekly. Qualification documents update annually. Most documents are structured Excel tables. Each row corresponds to an independent order or material detail, with fields including order number, printing format (unit: millimeters), paper grammage (grams per square meter), number of printing colors, delivery date, settlement unit price, and other fields. Some documents are PDF-format quality inspection reports, which include defect point markings, batch pass rates, and other content.
What constraints do these characteristics impose on deployment and upgrade?
The structured characteristics and update rhythm of packaging and printing due diligence data impose clear constraints on deployment and upgrade workflows. The multi-column, multi-field structure of Excel tables requires preset field mapping rules during deployment. This prevents unit confusion or field misalignment during parsing. Real-time updated production data requires continuity of data synchronization tasks during upgrades. Otherwise, due diligence report data will be delayed. The multi-row detail document structure requires adjusting segmentation rules to ensure complete contextual logic. Otherwise, retrieval results will be chaotic. During cross-version upgrades, the parameter format of old configurations must be compatible. This prevents service exceptions caused by changes to verification logic. It is also necessary to adapt to the new structure of workflow nodes to ensure that migrated workflows run normally.
How to configure the settings
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
PARSE_EXCEL_ROW_SEGMENT | Enabled, enforce single-row segmentation units | Each row in packaging and printing due diligence Excel data corresponds to an independent business detail. Row-by-row segmentation ensures complete contextual logic and resolves automatic segmentation chaos |
UPLOAD_FILE_MAX_SIZE | 2000 MB | Combined PDF quality inspection reports and order ledger Excel files for packaging and printing have large file sizes. This setting supports bulk upload requirements |
MONGO_CONNECTION_TIMEOUT | 600 seconds | Packaging and printing data volumes are large. Sufficient time must be reserved for database connection timeouts to prevent connection failures during upgrade restarts |
WORKFLOW_IMPORT_COMPATIBLE | Enable compatibility mode | When importing workflows across versions (such as v4.6.7 to v4.8.10), adapt to the new node parameter structure to avoid import failures |
PARSE_OCR_ACCURACY | High-priority mode | Defect markings in PDF quality inspection reports are critical information. This ensures OCR recognition accuracy |
RECALL_SIMILARITY_THRESHOLD | 0.75–0.85 | Order fields for packaging and printing have high similarity. A reasonable threshold must be set to filter irrelevant retrieval results |
The parameter values provided on this page are all common recommended starting points for configuration. Actual values are affected by material form, data volume, and business rules. Specific issues require individual analysis. It is recommended to test on your own samples before finalizing settings.
Three common configuration mistakes
- Symptom: After upgrading from v4.6.7 to v4.6.8 and modifying the Mongo configuration file, a
502 Bad Gatewayerror appears after restarting, and the platform cannot be accessed. Cause: The updated Mongo connection parameter verification logic adds required fields. Failure to modify the configuration to the new format causes database connection failure. - Symptom: After uploading multi-column Excel due diligence data, RAG retrieval results have chaotic contextual splicing. A single business detail is split into multiple segments. Cause: The
PARSE_EXCEL_ROW_SEGMENTconfiguration is not enabled. The default character-by-character segmentation rule is used, causing cross-row contextual splitting. - Symptom: When importing a workflow exported from v4.6.7 into v4.8.10, an error prompt about missing node parameters appears. Cause: Compatible import mode is not enabled. The parameter structure of new workflow nodes differs from the old version, and adaptation verification is not completed.
How to confirm proper configuration
- Upload a preset packaging and printing order Excel test file, view the parsed segmentation details, and confirm that each segment corresponds to a complete order or material detail row.
- Modify the Mongo database connection configuration, restart the service, and call the built-in health check interface to verify that the database connection status is normal and there are no timeout errors.
- Export an old-version workflow file, enable compatible import mode, upload it to the new-version platform, and verify that all workflow nodes are successfully loaded and parameters can be edited normally.
- Upload a single large-volume PDF quality inspection report, confirm that the upload process has no errors, the parsing task completes normally, and valid segments are generated.
