This page’s configuration rules apply to FastGPT v4.17.0 and later versions.
What the data for this category looks like
Typical entities for this category include raw material warehouses, line-side warehouses, finished product warehouses, and logistics and material control departments. Daily documents include receiving slips, putaway slips, material picking and return slips, warehouse transfer slips, inventory count sheets, lot ledgers, first-in first-out records, and expiration date records. Data sources include ERP/WMS systems, barcode or RFID equipment, procurement and work order information, warehouse location data, AGV or conveyor systems, and weighing data. Update frequencies fall into three categories: real-time, daily batch synchronization, and monthly inventory counts. Core business fields typically include unique identifiers such as material codes, lot numbers, warehouse location positions, and expiration dates.
What constraints do these characteristics impose on HTTP interfaces and external systems
Data sources for this category are scattered and have varying formats. This requires HTTP interfaces to support return formats from multiple systems, as well as both real-time and batch data pulling. The uniqueness and accuracy of core business fields directly affect the effectiveness of work instructions and technical standard Q&A, so interface parameters must be fixedly bound to unique fields such as lot numbers and warehouse locations. Differences in update frequencies require interfaces to support both short synchronous requests and asynchronous long task processing, to avoid timeouts caused by excessive data volumes. Additionally, the consequences of business errors are severe, so validation and retry mechanisms must be added during interface calls to ensure stable data interaction.
How to set the configurations
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
Authorization | Bearer {pre-generated system access token} | Complies with API authorization specifications for internal industrial systems, ensuring access security for warehousing and lot data |
| Request timeout threshold | 300-600 seconds | Warehousing and logistics interfaces often involve cross-ERP/WMS data pulling and barcode verification operations, so sufficient response time must be reserved |
variables | Bind fields to business documents: lot number, warehouse location code, expiration date | Core data for this category revolves around material lots and warehousing locations, so interface return values must be mapped to corresponding business variables |
responseData | Extract core validation fields: material code, lot status, warehouse location available quantity | Work instructions and technical standard Q&A require quick access to key information, so full interface data does not need to be returned |
| Async task polling | Poll every 30 seconds, retry up to 10 times | Tasks such as lot synchronization and file uploads for warehousing and logistics take a long time, so asynchronous processing is required to avoid request interruptions |
Three common mistakes
- Symptom: HTTP request returns a 504 timeout error, or the request disconnects automatically after no response. Cause: The timeout threshold was not adjusted for the time-consuming scenario of cross-system data pulling for warehousing and logistics, and the default timeout duration cannot cover operations such as barcode parsing and cross-ERP data synchronization.
- Symptom: After calling an external system interface, the returned fields do not match the warehousing business documents, or key fields are empty. Cause: The
variablesconfiguration was not used to correctly bind the unique business fields for this category, causing interface return values to fail to map to corresponding business variables. - Symptom: After uploading a lot ledger or inventory count file, it is impossible to confirm whether file indexing and data synchronization are complete. Cause: Async task polling rules were not configured, and task status fields were not extracted via
responseData, making it impossible to actively validate execution results.
How to confirm the configuration is complete
- Send a test request to the target warehousing system interface, verify that the
Authorizationheader is recognized normally, and no permission-related errors occur. - Trigger a simulated lot validation request, check that the fields bound via
variablescorrespond one-to-one with the fields on actual warehousing documents, with no missing or misaligned fields. - Initiate a long-running task such as a batch lot synchronization request, confirm that the system triggers status polling according to the configured rules.
- View the
responseDataextraction results from the interface return, confirm that they include the core validation fields required for work instructions and technical standard Q&A.
