What the data for this category looks like
Bulk commodity trading declaration materials and case file data mainly comes from three sources: enterprise internal ERP systems, customs declaration ports, and ownership registration platforms. Each individual case file contains multiple pages of structured sub-documents, including trade contracts, quality inspection reports, customs declarations, ownership certificates, and more. Core fields include commodity name, transaction quantity, unit price, customs declaration number, inspection batch number, and ownership number. Units are mostly specialized units such as tons, cubic meters, USD/ton, etc. Data is generated in real time with each trade transaction, and the length of a single document typically ranges from 5000 to 15000 characters.
What constraints do these characteristics impose on workflow orchestration
Bulk commodity trading declaration case file data characteristics bring three core constraints to workflow orchestration. First, multi-page long documents with scattered fields require the workflow to retain field identifiers during knowledge base chunking to avoid losing associated information after splitting. Second, data sources are scattered and generated in real time with transactions, requiring the workflow to support dynamic access to multiple data sources and scheduled synchronization. Third, a single case file is associated with multiple types of sub-documents, requiring workflow nodes to execute in the logical order of documents: first verify basic information, then call associated files. There are large differences in declaration formats across different bulk commodity categories, requiring the workflow to support switching corresponding rules via configuration.
How to set configurations
Reference only; verify against the target FastGPT release and deployment documentation.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
| Chunk Length | 800–1200 characters | Adapt to the paragraph length of bulk commodity declaration forms, retain complete core field groups such as commodity name and quantity |
| Overlap Length | 100–200 characters | Prevent field association breaks caused by long paragraph splitting, ensure the completeness of recalled content |
| Single Search Limit | Top 6 entries | Meet the recall requirements for matching multiple fields of a single case file, cover core information of associated sub-documents |
| Workflow Timeout | 300 seconds | Adapt to the average latency of cross-system calls to customs data and ERP interfaces, avoid task interruptions |
| Node Execution Order | Execute in the order bound to nodeId | Ensure the workflow triggers nodes sequentially according to the document verification logic |
| Variables | Trigger by document number | Bind exclusive data sources and verification rules for each trade order, avoid data confusion across different documents |
Three Common Misconfigurations
- Workflow execution returns empty fields. This occurs when core field identifiers of the declaration form are not retained during chunking, causing recalled content to fail to match query keywords.
- Workflow fails to call databases or tools after triggering. This occurs when
variablesare not correctly configured to bind data source permissions, resulting in nodes lacking access rights. - Workflow times out with an error (status code 504). This occurs when a reasonable timeout period is not set, and the waiting duration exceeds the threshold when calling customs data across systems.
How to Confirm Proper Configuration
- Upload a standard bulk commodity declaration form to the enterprise knowledge base, enter a query containing the customs declaration number, and check whether the recalled content includes complete core fields such as commodity name and transaction quantity.
- Trigger the configured workflow, view the node execution logs, and confirm that the time taken for each step does not exceed the set timeout period.
- Switch the knowledge base source bound to
variables, test bulk commodity declaration forms of different categories, and verify whether the workflow correctly calls the corresponding data sources. - Enter a query containing a specific inspection batch number, confirm that the audit results returned by the workflow match the quality inspection information in the document.
