What the data for this category looks like
Financing daily report data for the optoelectronics sector comes primarily from publicly disclosed listed company announcements on the Shanghai, Shenzhen, and Beijing Stock Exchanges, monthly statistical releases from industry self-regulatory organizations, and public securities firm research reports. The system updates all data uniformly after each day’s trading session ends. Each daily report document includes seven core fields: full company name, securities code, financing method, financing amount, disclosure date, investor entity, and affiliated sub-segment. All amount values use ten thousand yuan as the unit. The date format follows YYYY-MM-DD. Online links to original announcements are included with each report.
What constraints these characteristics impose on workflow orchestration
The daily updated data source requires a fixed trigger time to be configured for the workflow. This prevents early scraping of undisclosed information. Multiple data sources may contain duplicate entries. A data deduplication node must be configured to filter redundant content. The core fields include securities code and sub-segment. Classification filtering rules must be set to retain only financing entries from the optoelectronics sector. Attached original announcement links must be bound to final results to support subsequent preview calls for original documents. The amount field uses ten thousand yuan as the unit. A unit validation node must be configured to prevent mixed units from other categories that cause format errors.
How to set configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
Scheduled task cron expression | 0 18 * * * | Matches the update window after domestic securities market daily trading ends, avoiding scraping undisclosed data |
Data deduplication matching fields | Full company name + Disclosure date | Filters duplicate financing announcement entries for the same company on the same day |
Pull entry limit | Top 15 entries | Daily financing disclosures in the optoelectronics sector are limited, so excessive redundant content does not need to be pulled |
Original file link binding switch | Enabled | Associates original announcement links to support subsequent online preview calls for original documents |
Field format validation rule | Amount field must be validated for ten thousand yuan unit | Aligns with the unified amount measurement standard for this category of data, preventing format errors |
Node timeout period | 600 seconds | Adapts to the time required for multi-source data pulling and cleaning |
The parameter values provided on this page are general recommendations to serve as a starting point for configuration. Actual values are affected by material form, data volume, and business rules. Each case requires specific analysis. It is recommended to test on your own samples before finalizing settings.
Three Common Mistakes
- Symptom: The tool call node stops directly after execution with no return results. Cause: No access permission whitelist is configured for the data source, so the workflow cannot pull public data from the stock exchanges.
- Symptom: Generated share links point to local addresses. Cause: No public network access domain name is configured during deployment, only the default local port configuration is retained.
- Symptom: The original file online preview function cannot be invoked. Cause: The original announcement link field is not bound in the workflow, only cleaned structured data is imported.
How to confirm the configuration is correct
- Manually trigger the workflow to verify if returned results match the preset optoelectronics sector filtering conditions.
- Check workflow run logs to confirm the scheduled task executes at the configured time, with no node timeouts or error records.
- Inspect the format of result fields to confirm the amount unit conforms to the category’s unified standard, with no abnormal content.
- Test link jumps in results to confirm the original announcement page can be accessed normally.
