What the data for this category looks like
Core data for warehousing and logistics originates from systems including warehouse management systems (WMS), RFID sorting terminals, express sorting systems, employee attendance terminals and scheduling systems, and capacity scheduling systems. Data update frequencies fall into three categories:
- Real-time data such as sorting progress and employee clock-in records, updated every second or minute
- Inventory data and inbound/outbound document data, updated daily
- Monthly capacity reports, updated monthly
Document structures primarily use structured documents, including fields such as inbound ID, SKU code, inventory quantity, warehouse area number, inbound time, and employee ID. Most field units are pieces, pallets, and hours. Time formats follow the ISO 8601 standard, and employee IDs are fixed-length strings.
What constraints do these characteristics impose on the tool calling and plugins workflow
The high-frequency updates of real-time sorting data require tool call response latency to be controlled at the second level. Otherwise, real-time scheduling of sorting nodes will be affected. Structured documents with multiple fields require tool calls to strictly match field names and formats, to avoid call failures caused by parameter incompatibility. Differences in update frequencies require tool calls to distinguish data source types: real-time data must skip caching and read directly, while non-real-time data can be configured with a reasonable caching period to balance real-time performance and call efficiency. The fixed format of employee attendance data requires field type validation during tool calls, to prevent parsing failures caused by invalid characters or format errors.
How to configure the settings
| Configuration Item | Recommended Setting | Rationale | |
|---|---|---|---|
| Tool calling mode | toolChoice | Auto | Adapts to scenarios of parallel tool calls for warehousing and logistics, covering core needs such as inbound and outbound query, employee attendance query |
| Tool calling timeout | 600 seconds | Tool calls for warehousing and logistics mostly involve combined queries across multiple data sources; 600 seconds covers the response window for complex report generation | |
| Number of entries returned per tool call | First 10 entries | Document data volume for warehousing and logistics is moderate; 10 entries covers core information for a single query and avoids returning redundant data | |
| Field validation rules | Validate by SKU code and inbound time format | Data field formats for warehousing and logistics are fixed; validation can filter invalid call requests | |
| Cache expiration time | 30 minutes | Inventory data is updated daily; a 30-minute cache balances real-time performance and call efficiency | |
| Tool call trigger condition | Triggered by user questions | Adapts to internal office tool call scenarios for warehousing and logistics; triggers only when there are office or service needs to avoid invalid calls |
Three common mistakes
- Tool calls return empty results. Cause: The dedicated data source interface for warehousing and logistics is not correctly bound. For example, the inbound and outbound data interface of the WMS system is not associated, so valid information cannot be obtained.
- Tool calls throw an Invalid JSON error. Cause: Tool parameters contain line breaks or invisible control characters. Special symbols are included in warehouse area names for warehousing and logistics, and no escape processing is performed, triggering format validation failure.
- Tool calls time out. Cause: A reasonable timeout period is not set. Complex report queries exceed the preset 600-second threshold, leading to call interruption.
How to confirm the configuration is complete
- Trigger an inbound and outbound data query tool, and check whether the returned results include core fields such as SKU code and inbound quantity.
- Call the employee attendance query tool, and check whether the returned result format conforms to the preset ISO 8601 time format.
- Simulate a query for a warehouse area name containing special characters, and verify that the corresponding data can be correctly parsed and returned.
- View the tool call logs in FastGPT v4.17.0 to confirm that the timeout configuration is set to 600 seconds.
