What the data for this category looks like
Financial report data related to coke mainly comes from regular reports of listed coal-coke enterprises, monthly operation briefs released by industry self-regulatory organizations, and quality standard documents for coke delivery products from domestic futures exchanges.
Data update rhythms fall into three categories: regular reports are updated quarterly and annually, industry briefs are updated monthly, and delivery standard documents are revised annually.
Document structures include structured production and operation data tables, business segment analysis text, and quality indicator description chapters. Fields covered include production capacity scale, daily average output, average ex-factory price, particle size composition, and crushing strength. Corresponding units are ten thousand tons, tons, yuan/ton, millimeters, and megapascals.
What constraints do these characteristics impose on workflow orchestration
Data sources are scattered, so the workflow must be configured with multiple data source pull nodes to connect enterprise financial reports, industry briefs, and standard documents.
Different data sources have different update rhythms. This requires setting layered scheduled trigger rules that match quarterly and monthly update cycles.
Documents contain both structured tables and unstructured text. Parsing rules must be configured separately: extract structured content from tables, and perform segment processing on text content.
Specific fields and unit requirements add a need for a data validation step. This filters extraction results that do not meet unit specifications, avoiding data bias in subsequent analysis.
The coke industry also requires data association across production, sales, and futures segments. This means the workflow must include branch orchestration logic, triggering different processing branches based on report type.
How to set the configurations
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
PARSE_TABLE_ENABLE | Enabled | Coke financial reports contain large volumes of structured production and sales data tables. Enabling this allows accurate extraction of core business fields |
SCHEDULE_CRON | 0 0 1 1,4,7,10 * (quarterly trigger) and 0 0 1 * * * (monthly trigger) | Matches the quarterly disclosure rhythm of enterprise financial reports and monthly update rhythm of industry briefs |
Segment Length | 1200-1500 characters | Covers core information in the industry analysis chapters of coke financial reports, while avoiding exceeding model context limits |
VAR_ALLOWED_TYPES | ["file", "number", "string"] | Supports uploading coke test reports, calling numeric capacity data, and passing text-based analysis instructions |
PARSE_FILE_TIMEOUT_SECONDS | 900 seconds | Adapts to the file size of annual reports from large coke enterprises, preventing parsing interruptions due to timeout mid-process |
Similarity Threshold | 0.75 | Filters low-relevance non-financial report documents, retaining highly matched industry data and enterprise announcements |
The parameter values provided on this page are common recommended starting points for configuration setup. Actual values are affected by material format, 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 mistakes
- Phenomenon: AI chat node returns context over-limit error with status code 413. Cause: The
maxContextparameter is not configured to limit input length, and no input length validation node is added. - Phenomenon: Global variables selected for the custom knowledge base cannot properly associate data, and output fields are empty. Cause: The
VAR_ALLOWED_TYPESparameter is not set correctly, and the variable type associated with the knowledge base is not specified. - Phenomenon: File upload node cannot trigger document parsing, and the interface prompts that the file format is not supported. Cause: The
PARSE_TABLE_ENABLEparameter is not enabled, orUPLOAD_FILE_MAX_SIZEis set too small, exceeding the conventional file size of coke financial reports.
How to confirm the configuration is complete
- Manually trigger the workflow once, check that the parsed table fields include coke-related capacity and output indicators, with no irrelevant redundant fields.
- View the scheduled task running logs to confirm that the workflow runs automatically according to the set
SCHEDULE_CRONcycle. - Upload a test file of an enterprise's coke financial report, check that the parsing time does not exceed the threshold set by
PARSE_FILE_TIMEOUT_SECONDS. - Test input of ultra-long text, confirm that the input length limit interception is triggered, and no unresponsive or abnormal error is returned.
