Workflow Orchestration for Steel Trade Intelligent Due Diligence Reports

Steel trade intelligent due diligence data sources include contract documents of both buyers and sellers, steel mill delivery orders, logistics

What the Data for This Category Looks Like

Steel trade intelligent due diligence data sources include contract documents of both buyers and sellers, steel mill delivery orders, logistics waybills, bank payment slips, customs declaration forms, and capacity circulation data from industry associations. Data update rhythm falls into two categories: document data for individual trades is uploaded in real time along with the transaction process, while industry macro data is updated on a fixed monthly schedule. The document structure is divided into four modules:

  • Basic trade information module: includes contract number, buyer and seller entity information
  • Goods ownership certificate module: includes steel grade, specification, net weight
  • Capital flow module: includes invoice information, settlement vouchers
  • Logistics module: includes warehouse receipts, transportation routes

Steel-related parameters must use standard grades (such as Q235, SPHC) and specifications (such as Φ16mm, 10mm*2000mm). Weight units are uniformly set to tons.

Constraints Imposed by These Characteristics on Workflow Orchestration

Multi-source data requires the workflow to connect multiple independent data pull nodes, which dock with contract systems, logistics systems, capital systems, and industry databases respectively. Cross-data source field mapping rules must be configured to resolve inconsistent field names across different systems. The real-time update rhythm of document data requires the workflow to support event-triggered mode, ensuring that due diligence reports for individual trades are generated immediately. Monthly industry data requires a scheduled trigger node to periodically synchronize and update report content. The complex document structure and segmented fields require the workflow to add verification nodes. These nodes verify the legality of steel grades, specifications, and weight units, and also verify cross-module field consistency, such as the matching degree between contract shipment volume and logistics net weight.

Configuration Settings

Configuration ItemRecommended SettingRationale
PARSE_FILE_TIMEOUT_SECONDS1200 secondsSteel trade due diligence documents include multiple attachments, with longer parsing time than general scenarios
WORKFLOW_TRIGGER_MODEEvent trigger + scheduled triggerBalance real-time uploads of individual trade documents and monthly updated industry data
FIELD_MAPPING_RULEMap by document type + manual completionField names vary across different source documents; for example, the "net weight" on a delivery order corresponds to "shipment volume" on a contract
DATA_VALIDATION_RULEUnit verification + cross-field consistency verificationMost steel trade weight units are tons, and shipment volume matching across data sources must be verified
IMAGE_DISPLAY_CONFIGBind to corresponding goods ownership nodes by URL for renderingDue diligence reports need to display image resources such as steel quality inspection reports and warehouse photos
SPEECH_TO_TEXT_CONFIGAutomatically call the corresponding engine based on audio formatSome trade scenarios require processing communication records in audio format, so speech-to-text functionality needs to be configured
PROMPT_LANG_AUTO_SWITCHAutomatically switch based on request header languageAdapt to Chinese and English report requirements for domestic and foreign trade parties

The parameter values provided on this page are all conventional recommendations used as a starting point for configuration. Actual values are affected by material form, data volume, and business rules. Specific issues require case-by-case analysis, and it is recommended to test on your own samples before finalizing settings.

Three Common Mistakes

  • Workflow execution returns ETIMEDOUT or 504 Gateway Timeout error. The cause is failure to adjust the PARSE_FILE_TIMEOUT_SECONDS parameter; using the default value causes parsing timeout for steel trade documents with multiple attachments.
  • Images are not rendered in due diligence reports, or audio-format communication records cannot be converted to text content. The cause is failure to configure IMAGE_DISPLAY_CONFIG and SPEECH_TO_TEXT_CONFIG, and not enabling image rendering and speech-to-text functionality.
  • Confusing the usage boundaries between workflows and plugins, and failing to achieve automatic switching of Chinese and English opening remarks. The cause is failing to clarify that workflows are used to connect multiple sequential steps, while plugins are used to encapsulate single functions, and not enabling the PROMPT_LANG_AUTO_SWITCH configuration.

How to Confirm Proper Configuration

  • Upload a steel trade delivery order that includes multiple attachments, and check if the parsing duration in the workflow execution log matches the configured timeout threshold.
  • Upload due diligence materials that include image URLs and audio formats, and check if images are correctly rendered in the report and that audio materials have been converted to text content.
  • Use Chinese and English requests to call the report generation interface respectively, and check if the returned report opening remarks automatically match the request language.
  • Simulate real-time upload of individual trade documents and scheduled triggering of industry data synchronization, and check if the workflow executes according to the configured trigger mode.
