What data for this category looks like
Data sources for solid waste treatment financing daily reports include local ecological environment department solid waste disposal project filing ledgers, cooperative bank credit approval records, and public resource trading platform solid waste treatment project bid winning announcements. Data updates occur daily, with full aggregate data for the previous day generated on the same day. Document structure includes structured tables and attachments. Structured table fields include project number, disposal type, disposal volume, financing amount, project region, and approval status. Disposal volume unit is tons, financing amount unit is ten thousand yuan. Attachments are mostly project site photos and scanned measurement voucher documents.
What constraints these characteristics impose on the "workflow orchestration" link
Multiple data sources require the workflow to be configured with multiple interface pull nodes, connecting to public APIs or data export channels of the ecological environment department, bank, and trading platform respectively. The daily update rhythm requires a scheduled trigger cycle matching a 24-hour interval to avoid duplicate data pulls or missed data. The scenario with image and scanned document attachments requires integrating an OCR parsing node to extract measurement data from images. Fields with fixed units require adding field validation rules to ensure disposal volume and financing amount formats meet industry standards, preventing invalid data from entering subsequent stages. Cross-system data synchronization requirements also require configuring a retry mechanism to handle interface fluctuations from different platforms.
How to set configurations
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
schedule_cron | 0 8 * * * | Solid waste treatment financing daily reports are typically finalized before 8 AM daily. This configuration ensures data pull and generation processes trigger at a fixed daily time |
PARSE_IMAGE_ENABLE | Enabled | Daily report attachments are mostly project site photos and measurement vouchers. Enabling this configuration activates built-in OCR parsing capabilities to extract key data from images |
API_RETRY_MAX_TIMES | 3 | Multi-source data connection interfaces may experience temporary fluctuations. Setting 3 retries resolves temporary exceptions without affecting task progress |
FIELD_VALIDATION_RULES | Disposal Volume Unit: tons; Financing Amount Unit: 10k CNY | Core fields of solid waste treatment financing daily reports have fixed units. This rule validates field formats to prevent non-standard data from flowing into subsequent stages |
WORKFLOW_TIMEOUT | 600 seconds | Total time for multi-source data pull, OCR parsing, and field validation typically does not exceed 10 minutes. This configuration terminates abnormally timed-out tasks to avoid resource occupation |
The parameter values provided on this page are common 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 errors
- Symptom: Workflow API call returns 400 status code, and the
disposal_volumefield is empty. Cause:FIELD_VALIDATION_RULESis not configured, and non-standard disposal volume data is not filtered, leading to field validation failure and subsequent discarding of the field. - Symptom: Workflow execution log shows
timeouterror, and the task terminates early. Cause:WORKFLOW_TIMEOUTis set too short, failing to reserve reasonable time for multi-source data pull and OCR parsing. - Symptom: No valid financing data is returned after publishing the workflow via API, with a 500 status code returned. Cause: Authorization parameters for multi-source data interfaces are not configured, preventing external ledger data from being pulled.
How to confirm correct configuration
- Enter the workflow test panel, upload a simulated solid waste treatment financing daily report image and structured data, run the test, and check node output to confirm the
disposal_volumeandfinancing_amountfields are included with correct units. - View scheduled task historical execution records to confirm the task triggers automatically around 8 AM daily, with no timeout or interface error records.
- Call the workflow test API interface, pass simulated parameters, and check that the returned JSON data format matches the preset field rules.
- Temporarily set
API_RETRY_MAX_TIMESto 0, simulate an interface fluctuation scenario, and confirm the task triggers the retry mechanism and completes execution.
