What the data for this category looks like
This category of data originates from formulation and process libraries, raw material batch records, reactor DCS systems, weighing systems, LIMS, and warehouse management systems. Updates occur per production batch and each critical production step. Daily documentation includes batch production instructions, feeding verification sheets, reaction process logs, cleaning validation records, test reports, and deviation and change orders. Fields include batch identifiers, feeding parameters, reaction parameters, test results, and more. Units include kilograms, degrees Celsius, hours, and others. Given the production practice of switching between multiple product varieties and batches, data must be stored in isolated batch-specific dimensions.
What constraints these characteristics impose on the "HTTP Interfaces and External Systems" link
The production practice of switching between multiple batches requires interfaces to support dynamic batch parameter input, to pull cross-system data for the corresponding dimension. High update frequencies and real-time audit needs require interfaces to have low latency, to avoid delays in production audit workflows. Sensitive formulation and batch data require strict access permission controls for interfaces, to prevent information leaks. Differences across multiple system data sources require interfaces to adapt to varying system return formats, to ensure consistent data parsing.
How to set the configurations
| Configuration Item | Recommended Setting | Rationale for This Setting |
|---|---|---|
Authorization | Configure a Bearer token, set token validity period to 7200 seconds | Ensure access security for sensitive data such as formulations and batches, and comply with confidentiality requirements for fine chemical production |
variables | Pass three core variables: batch number, raw material batch number, and reactor number | Adapt to dynamic data pulling requirements for each production batch, and connect to batch dimension data from multiple systems |
responseData | Only return fields for feeding verification results, reaction end status, and cleaning check results | Compress transmission data volume to meet real-time requirements in production links |
| Interface call timeout | 600 seconds | Match the average operation duration of critical reactor steps to avoid interrupting the audit process due to timeout |
| Interface retry count | 3 times | Respond to temporary network fluctuations and ensure the stability of pulling data from multiple systems |
Three common errors
- Phenomenon: The interface returns a 401 unauthorized error, or sensitive fields are empty. Cause: The
Authorizationparameter is not configured correctly, or the token validity period is set too short, resulting in failure to normally pull production data. - Phenomenon: The number of returned results after calling the interface does not match expectations, or fields are missing. Cause: Correct batch parameters are not passed through
variables, causing the system to fail to match LIMS and DCS data corresponding to the production batch. - Phenomenon: Interface call times out, or failure persists after multiple retries. Cause: The interface timeout setting is shorter than the actual duration of critical reactor steps, or the actual delay of pulling data from multiple systems is not adapted to.
How to confirm the configuration is correct
Initiate a test call via the interface debugging tool of FastGPT v4.17.0, and check if the returned responseData field includes preset core audit results. Pass different batch numbers as the variables parameter, confirm that returned data changes with the batch number and matches document records for the corresponding production link. Simulate temporary network interruptions, check if the interface automatically retries according to the configured retry count, and can normally pull data after retries. Verify the access scope of the Authorization token, confirm that only data related to the currently configured production batch is permitted for access, and that no permission exists to access other batches or formulations beyond authorized scope.
