What data for this category includes
Data for this category primarily comes from ERP/WMS systems, barcode or RFID identification devices, purchase work orders, storage location management data, AGV transport systems, and weighing equipment. Daily generated documents include receiving slips, putaway slips, material picking and return slips, warehouse transfer slips, inventory checklists, lot ledgers, first-in first-out (FIFO) and expiration date records. Data update frequencies fall into three categories: real-time (for inbound/outbound and barcode scanning actions), daily (for inventory summaries), and monthly inventory (for book vs. physical stock reconciliation). Core fields include material code, lot number, storage location number, expiration date, and inbound/outbound quantity. Corresponding units include pieces, pallet positions, kilograms, and other standard units.
Constraints on HTTP Interfaces and External Systems
Data sources for this category are scattered, and update frequencies vary widely. Real-time barcode scanning requests require support for high-frequency calls, while monthly inventory tasks need support for bulk data transfer. HTTP interfaces must therefore adapt to different request frequencies and data transfer scales. Core fields include exclusive identifiers such as lot number and expiration date, so interfaces must define clear field mapping rules to avoid mismatches between general fields and business-specific fields. Additionally, the core requirements of book-physical stock consistency and lot traceability mean interfaces must verify the completeness of required fields. This prevents errors in subsequent process documents and exception reports caused by missing key business information.
Configuration Settings
This configuration applies to FastGPT v4.17.0.
| Configuration Item | Recommended Approach | Rationale |
|---|---|---|
Authorization | Bearer {API key of the connected external warehousing system} | Verifies call permissions between the external system and FastGPT, preventing unauthorized access |
variables | Pass business fields such as material code, lot number, and storage location number in key-value pair format | Injects warehouse-specific business data into the report generation process, ensuring report content matches actual warehouse status |
responseData | Structured fields including book-physical stock matching results, lot traceability chain, and expiration date check status | Synchronizes business verification results from the external system to the generated process documents and exception reports |
| Interface timeout setting | 600–1200 seconds, calibrated based on actual testing | Adapts to high-frequency calls for real-time barcode scanning and bulk data transfer for monthly inventory, avoiding interruptions to long-duration requests |
| Bulk request limit | No more than 500 entries per request | Adapts to bulk data upload requirements for monthly inventory, preventing interface overload |
Three Common Misconfigurations
- Failing to filter returned warehouse data by lot number when calling the interface. This occurs when the lot number is not passed as a filter parameter in
variables, leading the interface to return all business data. - Receiving a 401 Unauthorized error during interface calls. This occurs when the
Authorizationparameter is misconfigured, the key format is invalid, or a valid key is not provided. - Missing expiration date information in generated reports. This occurs when the
responseDatafield does not include expiration date check return fields, so verification data from the external system is not synchronized to the report.
How to Verify Successful Configuration
- Call the test interface with preset material codes and lot numbers, then check if
responseDataincludes the corresponding book-physical stock matching results. - Review interface call logs to confirm the
Authorizationparameter format is correct, with no unauthorized access errors. - Generate a test exception report and verify that the report includes the submitted business fields and verification results.
- Simulate a bulk request of 500 entries, then confirm the interface does not throw timeout or overload errors.
