What Data Looks Like for This Category
Data for refined petroleum product sales declarations and file reviews originates primarily from retail fuel station systems, invoicing ledgers, inventory transfer orders, and internal approval circulation archives. Data update frequencies range from real-time submission of individual orders to daily aggregated monthly reports. Documents primarily use structured forms, with supporting attachments including quality inspection reports and purchase vouchers. Core fields include fuel grade, sales volume, purchase and sales unit prices, approval nodes, submission time, and operator information. Common units are physical and monetary units such as liters, yuan, and tons.
How These Characteristics Impose Constraints on Workflow Orchestration
Declared sales data for refined petroleum products is scattered across multiple business nodes including fuel station systems, invoicing ledgers, and inventory systems. Workflows must connect to different data sources in sequence to gather complete file information, avoiding data silos. Individual declared files may include multiple attachments such as quality inspection reports and purchase vouchers. Workflows must support batch upload of multiple files and field binding. Approval nodes across different business stages follow a fixed circulation order. Form input must only trigger after preceding nodes are completed. Processing large volumes of monthly aggregated data increases single task execution duration. Workflows must adapt scheduling rules for long-running tasks.
Configuration Settings
Reference only; verify against the target FastGPT release and deployment documentation.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
| File upload node configuration | Allow simultaneous upload of 1-5 attachments, maximum single file size 1000 MB | Declared attachments for refined petroleum product sales are mostly quality inspection reports and purchase vouchers, with single files typically under 200 MB. Batch upload prevents timeouts caused by too many submissions at once |
variables binding rules | Bind core fields including fuel grade and sales volume to form input components, calibrate variable mapping rules based on actual testing | Core validation for refined petroleum product declarations relies on standardized fields. Precise binding prevents data extraction errors |
| Node execution timeout settings | Set single node timeout to 1200 seconds, set batch task timeout to 3600 seconds | Typical execution duration for individual file reviews is 300-600 seconds. Batch monthly data processing requires a longer timeout window |
| Form trigger condition | Trigger workflows only after preceding approval nodes are completed and all form fields are fully filled out | Refined petroleum product declaration approval processes follow a fixed sequence. Submissions before preceding nodes are completed will result in incomplete file information |
nodeId binding rules | Bind the approval node's nodeId to circulation order, calibrate node ID mapping based on actual testing | Refined petroleum product declaration approval processes follow a fixed node sequence. Precise binding ensures correct circulation logic |
| API callback configuration | Enable asynchronous task callback mode, set callback interval to 60 seconds | Batch declaration task execution duration may exceed 1200 seconds. Asynchronous callbacks prevent synchronous call timeouts |
Three Common Configuration Errors
- Phenomenon: When calling workflow APIs to process batch monthly declaration data, timeout status codes are returned or task execution is interrupted. Cause: Asynchronous task callback mode is not configured, and synchronous call timeout thresholds are not adapted for long-running tasks.
- Phenomenon: Uploaded files received by workflows cannot be bound to the
variablesparameter, causing subsequent validation nodes to fail to read attachment content. Cause: Variable mapping rules for file upload nodes are not correctly configured, and uploaded file objects are not bound to workflow variables. - Phenomenon: Users can still submit forms to trigger workflows before preceding approval nodes are completed, resulting in missing file information. Cause: Preceding node validation conditions for form triggers are not set, and workflows are not restricted to triggering only after preceding nodes are completed.
How to Verify Configurations Are Correct
- Submit an individual refined petroleum product declaration file, check that all core fields are correctly bound to workflow variables, and that attachments can be read in workflow nodes.
- Simulate a batch monthly declaration task, confirm that the workflow uses asynchronous callback mode and no synchronous call timeout issues occur.
- Intentionally skip preceding approval nodes when submitting a form, confirm that the workflow does not trigger execution, verifying that the trigger condition configuration is active.
- Upload multiple declaration attachments, confirm that the workflow can normally receive and process all uploaded files.
