What Data for This Category Looks Like
Data sources for duty-free intelligent due diligence reports fall into three categories: duty-free operation qualification documents filed with the national customs authority, policy announcements for offshore duty-free and cross-border duty-free, and supplier supply detail vouchers. Update cycles are not fixed. Policy documents are updated irregularly per regulatory requirements. Operation qualifications undergo annual inspection and updates each year. Supply details are synchronized monthly. Document formats include PDF qualification scans, Word policy interpretation documents, and Excel supply ledgers. Fields include unified social credit code, qualification validity period, duty-free quota (unit: yuan per passenger), supply category code, and some policy texts contain nested clause structures.
What Constraints These Characteristics Impose on Workflow Orchestration
The need to access multiple data sources requires the workflow to configure cross-source synchronization nodes. These nodes connect to the qualification filing system, policy announcement library, and supply ledger system separately. This avoids information loss from single data sources. Irregular update cycles require the workflow to support both flexible scheduled triggering and manual synchronization. The workflow supports triggering manual synchronization immediately after policy release, preventing missed updates to temporary regulatory documents. Diverse document formats require the workflow to adapt parsing logic for different formats. Separate configuration of parsing parameters for tables and long texts ensures correct parsing of Excel supply ledgers and PDF qualification files. Special field units and codes require the workflow to add standardized field processing nodes. These nodes perform format verification and unified mapping for duty-free quotas and category codes. This avoids unit confusion or code errors in reports.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
segment_length | 800–1200 characters | Duty-free due diligence documents are mostly long texts with nested clauses. This length preserves contextual relevance while avoiding overloaded single segments |
schedule_cron | 0 0 2 * * * | Triggers synchronization daily at 2:00 AM. This aligns with the qualification annual inspection cycle and supports supplementary synchronization for temporary policy updates |
similarity_threshold | 0.75–0.85 | Duty-free policy texts are mostly clause-based. This threshold filters irrelevant related content while retaining core policy clauses |
PARSE_TIMEOUT | 600 seconds | Parsing large qualification files typically takes a long time. This duration covers the full parsing process |
retry_count | 3 times | Temporary network fluctuations may occur when accessing multiple data sources. This retry count reduces the probability of synchronization failures |
plugin_retry_times | 2 times | Temporary exceptions may occur when calling external qualification verification interfaces. This retry count improves interface call success rates |
The parameter values provided on this page are common starting points for configuration. Actual values are affected by document format, 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 importing the workflow to another environment, the referenced qualification verification plugin fails to load. The interface displays the "Plugin not found" prompt. Cause: When exporting the workflow, only the JSON structure file was exported. Local configuration and dependency files for the plugin were not included. This causes the imported environment to fail to recognize the plugin path.
- Symptom: When parsing an Excel file of duty-free supply details, some category code fields are empty. Cause:
PARSE_FILE_TYPEwas not configured asexcel. The default parsing logic only recognizes plain text formats and cannot parse nested content in table cells. - Symptom: The workflow returns a
504 Gateway Timeouterror after triggering. Cause: ThePARSE_TIMEOUTsetting is lower than the actual parsing time of large qualification files. This causes the parsing process to terminate before completion.
How to Confirm Proper Workflow Configuration
- Manually upload a single duty-free operation qualification PDF file. Check if the parsed fields include required items such as the unified social credit code and qualification validity period.
- Trigger a manual synchronization task. Check the access logs for multiple data sources to confirm that all data sources have completed data pulling and parsing.
- Call the workflow to generate a single test due diligence report. Check if dynamic fields such as duty-free quotas and policy clauses are correctly replaced in the report.
- Export the JSON file of the current workflow. Import it to a test environment to confirm that all referenced plugins and nodes load normally and have no configuration errors.
