What the data for this category looks like
Data for bid rejection tendering reports primarily comes from public procurement service platforms, official bid rejection announcements published by tendering agencies, and internal bid evaluation archive records from financial institutions. Data updates are triggered when a single project’s bid rejection announcement is released, with each update only covering the bid rejection information for that single tendering project. Each data document includes fields such as project number, project name, bid rejection reason category, list of involved bidders, announcement release time, and contact information of the purchasing unit. Most fields use plain text, string, or array formats, with no unified quantitative units.
What constraints do these characteristics impose on workflow orchestration?
Data sources are scattered across multiple public platforms and internal archive systems, requiring workflow configurations to include multi-source data pull nodes that adapt to authentication and format requirements of different APIs. Update triggers rely on the release event of a single project’s bid rejection announcement, which cannot be fully covered by fixed-cycle polling, so event trigger nodes must be configured to adapt to single-project-level updates. The fields include an array-formatted list of involved bidders, requiring array parsing nodes to split the array into individual fields. Bid rejection reasons exist as free text, requiring text preprocessing nodes to unify formats and avoid parsing errors in subsequent steps. The volume of each data document is small but sources are scattered, so concurrency control nodes must be configured to limit the number of requests pulled in a single operation, avoiding interface rate limits.
Configuration Settings
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
workflow_trigger_mode | Event trigger, bound to bid rejection announcement push API | Bid rejection item data only updates when a single project’s bid rejection announcement is released, eliminating the need for fixed-cycle polling |
PARSE_ARRAY_FIELD_ENABLE | Enabled, specify the involved bidder field | Raw data includes an array-formatted list of involved bidders, which must be split for use in subsequent workflows |
TEXT_PREPROCESS_TIMEOUT | 30 seconds | Most bid rejection reason texts are under 500 characters; 30 seconds covers complete format unification and keyword extraction processes |
CONCURRENT_REQUEST_LIMIT | 2 concurrent requests | Public tendering platform interface rate limits typically range from 1 to 3 requests per second per IP; 2 concurrent requests adapts to most public data sources |
UPLOAD_FILE_MAX_SIZE | 10 MB | The size of individual bid rejection announcement documents usually does not exceed 10 MB, so this value covers most scenarios |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Parsing a single document under 10 MB takes no more than 600 seconds, preventing mid-process timeout interruptions |
The parameter values provided on this page are common recommended 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
- Symptom: A "400 Bad Request" error is returned when calling the workflow API, with a prompt indicating the missing
filefield. Cause: The uploaded bid rejection announcement file was not configured as a workflow input parameter, resulting in the API request not carrying a valid identifier for the corresponding file. - Symptom: After the workflow executes, the involved bidder field is not correctly split and remains in array format. Cause: The
PARSE_ARRAY_FIELD_ENABLEconfiguration item was not enabled, and the target field to split was not specified, resulting in the array field not being parsed into individual entries. - Symptom: The workflow execution times out, with a status code of "504 Gateway Timeout". Cause: A reasonable
TEXT_PREPROCESS_TIMEOUTvalue was not set, and the bid rejection reason text preprocessing process exceeded the system’s default timeout threshold, causing the workflow to interrupt.
How to Confirm Proper Configuration
- Manually trigger the workflow, upload a bid rejection announcement document matching the business scenario, and verify that execution logs for each data source node indicate successful pull operations.
- Review the workflow’s input parameter configuration to confirm that allowed file upload types align with the formats of the announcement documents in use.
- Inspect the array field parsing node configuration to confirm that the involved bidder field has been bound, and verify that parsed results are split into individual entries post-execution.
- Access the system log panel to confirm that workflow execution records are properly stored with no abnormal errors.
