What the Data for This Category Looks Like
Tender announcement data comes from public resource trading platforms at all levels, official government procurement websites, and public disclosure channels of industry authorities. Update frequency adjusts based on tender project progress. Regular projects receive multiple daily updates, while emergency procurement projects use real-time pushes. Document structures include core metadata fields such as tender number, purchaser entity, project budget, qualification thresholds, bid deadline, bid opening location, and attached PDF-format tender documents. For field units, budget is marked in ten thousand RMB. Time fields uniformly use the Gregorian year-month-day format. Some projects include sub-item fields for section splitting.
Constraints on Workflow Orchestration
Multi-source heterogeneous data sources require configuring multi-format parsing rules to match metadata field positions across different platforms. The high-frequency update feature requires workflows to use scheduled triggering or real-time webhook triggering modes to avoid data delays. Attached PDF tender documents require workflows to integrate a file parsing node to complete text extraction and structuring. Differences in field formats and units require configuring standardized conversion rules to unify budget units and time formats. The wide range of single-document content lengths requires workflows to adapt to context configurations for long-text processing.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | PDF tender documents attached to tender announcements typically have a large number of pages, so sufficient parsing time must be reserved to avoid timeout interruptions |
max_context_length | 8000–12000 characters | The text length of single tender announcements varies widely, adapting to context processing requirements for long documents |
workflow_trigger_type | Scheduled trigger (every 30 minutes) + real-time webhook | Balances the needs of regular batch updates and real-time push for emergency projects |
field_mapping_rule | Match using preset templates per source platform | Metadata field naming varies widely across different tender platforms, so dedicated mapping rules must be configured per source |
form_data_file_field | Tender Attachment | When calling a third-party interface to upload tender documents in the workflow, the identifier name of the corresponding file field must be specified |
UPLOAD_FILE_MAX_SIZE | 500 MB | Large PDF tender document attachments typically have a large size, adapting to attachment upload limits for regular projects |
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, and it is recommended to test on your own samples before finalizing settings.
Three Common Configuration Mistakes
- Phenomenon: Workflows generate normal results in the run preview page, but return no content when called via the chat window. Cause: No workflow authorization rules for chat window triggering are configured, or correct context parameters are not passed during triggering.
- Phenomenon: When configuring a form-data type HTTP request in the workflow, tender document attachments cannot be passed correctly. Cause: The form-data file field identifier name is not specified, or the correct file input node is not bound.
- Phenomenon: A "Load file error" prompt appears when uploading tender document attachments to a workflow node, but direct upload to the knowledge base works normally. Cause: The workflow node's file parsing configuration does not match the attachment format, or the temporary storage threshold is set too low.
How to Confirm Proper Configuration
- Trigger a workflow test, verify that metadata fields have completed standardized conversion as configured, and confirm that fields from different source tender announcements match consistently.
- Upload a test PDF tender document, check that the file parsing node extracts text normally with no error prompts.
- Configure test tasks for scheduled triggering and webhook triggering, verify that the workflow starts normally in high-frequency update scenarios.
- Call the workflow via the chat window triggering method, confirm that returned results match the preview page with no missing parameters.
