Citation Sources and Provenance for Vehicle Financing Daily

What This Category’s Data Looks Like

The data sources for vehicle financing daily reports primarily include public API interfaces from partner supply chain financial service providers, dealer financing ledger systems of vehicle manufacturers, and public vehicle transaction filing data. Data is synchronized in full batches for the previous working day every midnight. Each structured data entry includes fields such as vehicle identification number, dealer entity name, credit limit, daily loan amount, due repayment date, and payment status. The unit for credit limits is Renminbi yuan, and date fields use the ISO 8601 standard format.

Constraints Imposed on the Citation Sources and Provenance Workflow

Multi-data-source access requires the provenance chain to associate a unique identifier for each data source, to ensure traceability to the specific interface or ledger system. Daily full-data updates require labeling the data synchronization batch time in provenance information, to avoid referencing expired or duplicate data. Using vehicle identification number as the unique identifier requires binding this field as the core association condition during provenance, to prevent confusion between financing data of different vehicles. Using Renminbi yuan as the credit limit unit requires clearly marking the currency in provenance information, to avoid errors from cross-currency calculations. Financial compliance requirements require retaining complete call chains and data verification records, to ensure provenance information can be used for audits.

How to Configure Settings

Configuration Item	Recommended Value	Rationale
`recall_count`	`Top 10 entries`	Vehicle financing daily reports have concentrated fields per entry, with core financing information in the top few matching results. Excessive recall leads to redundant context
`similarity_threshold`	`0.75-0.85`	Vehicle identification number is used as the unique identifier, so a high matching degree is needed to avoid confusion between different VINs, while covering approximate spelling scenarios for dealer names
`UPLOAD_FILE_MAX_SIZE`	`200 MB`	Batch data files for vehicle financing daily reports may contain tens of thousands of records, so support for large single-file upload capacity is required
`PARSE_FILE_TIMEOUT_SECONDS`	`600 seconds`	Batch parsing of large financing daily report files takes extended time, preventing mid-parsing timeout interruptions
`citation_provenance_toggle`	`Enabled`	Financial scenarios require retaining complete data reference chains to meet compliance audit requirements
`rerank_return_count`	`Top 5 entries`	Core financing information does not need excessive redundancy; only the most relevant provenance data after reranking should be retained

The parameter values provided on this page are common starting points for configuration. Actual values are affected by material format, data volume, and business rules. Specific issues require specific analysis, and it is recommended to test against your own samples before finalizing values.

Three Common Misconfigurations

Symptom: An input error occurs when clicking run after referencing a configured vehicle financing daily report plugin in a workflow. Cause: The plugin's input parameter validation rules were not correctly configured, and passing vin_code as the core retrieval condition was not required, leading to failure to match precise data during retrieval.
Symptom: A 408 Request Timeout error is returned after calling the plugin. Cause: The PARSE_FILE_TIMEOUT_SECONDS parameter was not adjusted, exceeding the default timeout period when batch parsing large financing daily report files.
Symptom: When configuring recall_count, the selectable range only includes discrete values such as 100, 900, making it impossible to select a value around 300. Cause: The system's default recall count configuration item uses a segmented selectable range and does not offer custom input functionality, leading to an inability to match precise recall quantity requirements.

How to Confirm Configuration Is Complete

Upload a test vehicle financing daily report file, view the parsed field list, and confirm that core fields such as vin_code and financing_amount have been correctly identified.
Initiate a knowledge base recall test, check whether the number of returned results matches the configured recall_count value, and confirm that the configuration is active.
View the provenance information of recall results, confirm that it includes data source interface identifiers, synchronization batch time, and vin_code association information, to meet compliance requirements.
Adjust the similarity_threshold value, initiate a test recall, and confirm that the relevance of matching results changes as expected with the threshold.
