What This Type of Data Looks Like
Coal transportation and sales business data primarily comes from internal waybill management systems, weighing systems, cargo right registration ledgers, and transportation scheduling platforms. Data updates trigger with business nodes. Each completed shipment, weighing, or cargo right transfer operation updates the corresponding record. Individual business documents include fields such as cargo right number, departure location, destination location, approved tonnage, transportation vehicle license plate, weighing time, carrier information, and more. Most field units are tons, trips, and hours. Some associated fields must match real-time transportation capacity status.
Constraints on Forms and Interactions From These Data Characteristics
Coal transportation and sales business data has many closely linked fields. Forms must be split by business nodes. Too much information on a single page can cause filling errors. The real-time data update feature requires interactive components to support dynamic option loading, instead of static preset drop-down lists. Business documents such as weighing slips and transportation contracts have large file sizes. Upload components must support large-capacity files and multiple formats. Some fields like tonnage require strict numerical format matching. Targeted validation rules must be configured to ensure data compliance.
Configuration Settings
| Configuration Item | Recommended Approach | Rationale |
|---|---|---|
formInput | Split by business nodes, 800–1200 characters per section | Adapt to segmented filling habits of coal transportation and sales business forms, avoid single-page information overload |
userSelect | Bind to real-time business data sources, drop-down option update interval no more than 300 seconds | Match real-time changes in coal transportation and sales transportation capacity and cargo rights |
| File upload configuration | Support maximum 1000 MB per file, allow jpg, png, pdf formats | Meet size and format requirements for business documents such as weighing slips and transportation contracts |
| Dynamic association trigger | Automatically load corresponding transportation vehicle information after selecting cargo right number | Align with associated data logic of coal transportation and sales business |
| Input validation rules | Set positive integer validation for tonnage fields, unit is tons | Ensure correct format of business data |

Three Common Misconfigurations
- The form page does not show the file upload entry, preventing submission of business attachments such as weighing slips. This happens when the display switch for the file upload component is not enabled in the form configuration.
- After selecting a cargo right number, the transportation vehicle list does not update automatically. This happens when the
userSelectcomponent is not bound to a real-time business data source, or the update interval is set too long. - A parameter error returns after form submission, and the weighing tonnage field shows empty. This happens when no format validation is set for the numeric field, so non-numeric content cannot be recognized by the system.
How to Verify Successful Configuration
- Enter the form editing page, confirm all required fields for coal transportation and sales business are present, including cargo right number, tonnage, transportation vehicle information, and others.
- Simulate selecting a cargo right number, check if the corresponding transportation vehicle list loads automatically to confirm the dynamic association logic works.
- Try uploading a jpg format file, confirm the upload entry displays normally and the file size meets preset requirements.
- Enter non-numeric content in the tonnage field, check if the system displays a format validation prompt to confirm the validation rules work.
