What Data for This Category Looks Like
Data for this category originates from PLM, ERP, and MES systems, supplier documentation, validation test records, and customer-specific requirement documents. Daily produced and circulated documents include ECN/ECR forms, change assessment reports, drawing and BOM version records, process validation reports, production switching plans, inventory disposal documents, and customer approval documents. Data updates have no fixed cycle; they are triggered by each process or engineering change, and involve collaborative circulation across R&D, process, quality, production, and procurement teams.
What Constraints These Characteristics Impose on Workflow Orchestration
Multi-source heterogeneous data sources require the workflow to be configured with cross-system data pull nodes, adapting to the interface formats of different systems such as PLM, ERP, and MES. The lack of a fixed update cycle requires the workflow to use change triggers as startup conditions, without relying on scheduled scheduling rules. Multiple types of associated documents require the workflow to support multi-node parallel verification, ensuring that documents such as ECNs, process validation reports, and customer approval files circulate synchronously. Scenarios involving cross-team participation require the workflow to be configured with node permission groups, restricting the operation scope of different roles on change approval nodes.
Configuration Recommendations
This configuration applies to FastGPT v4.17.0.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
variables | Bind change order ID, BOM version number | Associate corresponding change data pulled from multiple systems, ensuring the workflow context accurately matches the current change request |
nodeId | Assign in the order of change process steps | Ensure the workflow node execution sequence aligns with the actual change approval and verification process, avoiding execution misalignment |
| Timeout Threshold | 600 seconds | Adapt to the average response time of cross-system data pulls from PLM and ERP, preventing workflow interruptions caused by invalid waiting |
| Context Length | 800–1200 characters | Adapt to the content length after splicing multiple documents, avoiding exceeding the model's processing limit |
| Number of Parallel Processed Documents | First 3 items | Adapt to the scenario of synchronous verification of multiple documents, processing associated files such as process validation reports and switching plans simultaneously |
| Judgment Rule | Match the "customer approval document exists" field | Correspond to the mandatory requirement of customer approval for this category, ensuring the change process complies with compliance requirements |
Three Common Misconfiguration Issues
- Phenomenon: The judge triggers the ELSE branch when matching "equals" or "starts with" rules, and triggers the IF branch when matching "contains" or "ends with" rules. Cause: The string matching logic of the judge is not configured correctly, causing the rule matching order to differ from expectations.
- Phenomenon: The workflow cannot obtain parameters passed by the system, and the corresponding fields do not exist in the global variables. Cause: System parameter mapping is not configured in the workflow startup node, causing parameters to not be correctly written to the
variablesstorage area. - Phenomenon: The workflow does not correctly process the returned content after calling an external interface, triggering a timeout error. Cause: A reasonable timeout threshold is not set, or the analysis node for the interface returned content is not configured, causing the workflow to fail to recognize valid responses.
How to Verify Proper Configuration
- Submit a test change order, check whether the workflow starts the corresponding nodes in the preset order.
- View the
variablesstorage area, confirm that parameters such as change order ID and BOM version number have been correctly bound. - Simulate triggering different matching rules, verify whether the judge's branch logic meets expectations.
- Check the cross-system node call logs, confirm that data pulling has been completed normally.
