What the data for this category looks like
Commercial vehicle financial report data primarily comes from quarterly public financial reports released by vehicle manufacturers, Ministry of Industry and Information Technology vehicle production catalog announcements, and monthly operation monitoring data from industry associations. Updates follow two schedules: core operating data is disclosed on a fixed quarterly basis, while vehicle filing, production capacity, and dealer inventory data are updated irregularly.
Each financial report document includes fields such as segmented vehicle sales, production cost composition, per-vehicle operating costs, and channel inventory turnover. Common units include units, ten thousand yuan, and per 100 kilometers. Some fields cover commercial vehicle-specific dimensions such as single-batch production capacity and per-vehicle maintenance costs.
What constraints these characteristics impose on HTTP interfaces and external systems
Quarterly bulk financial report data has a large volume, which imposes constraints on the load capacity of single interface requests. Interfaces must support batch upload or paginated data pulling. Irregularly updated vehicle filing and production capacity announcements require interfaces to support dynamic trigger calls, to adapt to non-fixed scheduling scenarios.
Multi-dimensional segmented fields such as per-vehicle operating costs and single-batch production capacity require interfaces to support pulling specified fields, reducing invalid data transmission. Differences in data formats across multiple sources require interfaces to support multi-format parsing and adaptation, avoiding data parsing failures.
How to set configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
UPLOAD_FILE_MAX_SIZE | 1000 MB | Single commercial vehicle quarterly financial report documents include multi-page segmented vehicle data, and their volume is typically larger than general financial report documents |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Table parsing and field extraction for multi-page financial reports require longer processing time, adapting to the parsing rhythm of large documents |
API_BATCH_SIZE | 20–30 items | Single batch of financial report data includes multiple segmented vehicle reports. Controlling batch quantity avoids interface overload |
FIELD_FILTER_ENABLE | Enabled | Commercial vehicle financial reports include a large number of specialized segmented fields. Enabling this allows pulling specified data on demand, reducing redundant transmission |
DYNAMIC_TRIGGER_ENABLE | Enabled | Commercial vehicle announcement data is updated irregularly, requiring support for interface calls with non-fixed scheduling |
EMBEDDING_BATCH_SIZE | 10–15 items | Vector generation for multiple fields in a single financial report requires adapting to batch processing rhythm, avoiding model request timeouts |
The parameter values provided on this page are common recommended starting points for configuration. Actual values are affected by material format, data volume, and business rules. Specific issues require case-by-case analysis. It is recommended to test on the reader’s own samples before finalizing settings.
Three common mistakes
- Calling the document insertion interface returns the
413 Request Entity Too Largestatus code. The cause is failure to adjust theUPLOAD_FILE_MAX_SIZEconfiguration, which does not adapt to the large document volume of commercial vehicle financial reports. - Testing the multimodal Embedding interface fails, returning an error response starting with
Invalid. The cause is failure to adjustEMBEDDING_BATCH_SIZEfor the multi-field data of commercial vehicle financial reports, leading to batch requests exceeding model load limits. - The data fields pulled by the interface are empty. The cause is failure to enable the
FIELD_FILTER_ENABLEconfiguration and specify the required commercial vehicle financial report-specific fields, resulting in return of redundant invalid data.
How to confirm configurations are correctly set
- Upload a single complete commercial vehicle quarterly financial report document. Check the upload status code and parsing progress returned by the interface to confirm that the configuration adapts to the document volume and processing duration.
- Initiate a dynamically triggered interface call. Check whether the interface successfully pulls announcement data during non-fixed scheduling periods to confirm that the dynamic trigger logic takes effect.
- Initiate a pull request specifying commercial vehicle financial report-specific fields. Check whether the returned data includes the specified fields to confirm that the field filtering rule takes effect.
- Initiate a batch document insertion request. Check whether the processing results returned by the interface meet the batch configuration requirements to confirm that the batch request logic functions normally.
