What the Data for This Category Looks Like
Data for this category comes from the engineering construction project approval management system, construction drawing review system, enterprise qualification database, and public credit platform. The update frequency is daily. Commonly processed documents include construction permit applications, construction drawing review qualification certificates, quality and safety supervision procedures, completion record forms, and more. Most document structures include fields such as project ID, participating unit qualification information, approval node status, and application material list. There is no unified fixed unit, and fields need to match the official filling requirements of the corresponding approval stage.
What Constraints These Characteristics Impose on Workflow Orchestration
Multi-source data access requires workflow configuration to include cross-system data pull nodes. The daily update frequency requires trigger nodes to run on a daily scheduled basis. Different approval documents have significant field differences, so different extraction rules must be preset by document type via variables. Participating unit qualification information requires connection to external qualification databases for verification. Workflows must embed verification nodes to prevent invalid material circulation. Errors in approval stages can lead to unlicensed construction or record filing failures. Workflows must set pre-verification nodes to block abnormal data. They must also support parallel and serial scheduling logic for different approval nodes to adapt to parallel approval business scenarios for engineering approval.
How to Set Configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
variables | Set project ID, participating unit qualification, and approval node status as three types of variables grouped by approval document type | Match core fields of documents in this category, adapt to extraction rules for different materials |
| Single search limit | Top 5 entries | Match the conventional return count of qualification databases and credit platforms, avoid redundant data |
| Maximum context | 8000–12000 characters | Adapt to the average length of engineering approval documents, avoid context truncation |
| Workflow trigger mode | Triggered by approval node submission | Match the business process nodes of engineering approval, avoid invalid runs |
nodeId | Assign unique identifiers to cross-system data pull and qualification verification nodes | Facilitate locating abnormal nodes and troubleshooting operational faults |
| Timeout setting | 600 seconds | Adapt to the conventional response duration of cross-system data pulls, avoid process blocking |
Three Common Errors
- Phenomenon: Workflow runs normally in preview, but no results are returned on the chat page. Cause: No context transfer rules are configured for the chat scenario, so the context of the approval process is not synchronized to the dialogue link.
- Phenomenon: Workflow canvas drags with lag, and operation response is delayed. Cause: Using the workflow engine of FastGPT v4.6.5 or earlier versions, the node rendering optimization function added in FastGPT v4.17.0 is not enabled, and the number of nodes exceeds the performance threshold of the current version.
- Phenomenon: Search results do not combine the context of the current approval project, returning irrelevant general engineering documents. Cause: The project number in
variablesis not passed as a search context parameter, so the search scope is not limited to the corresponding approval project.
How to Confirm Proper Configuration
- Trigger a simulated approval submission, check whether the workflow runs in sequence according to preset nodes, and whether variables of each node are correctly extracted from corresponding documents.
- View workflow logs, confirm that the return results of cross-system data pull nodes are consistent with the content of external data sources.
- Simulate abnormal input with missing core fields, check whether the verification node triggers interception and returns corresponding prompts.
- Initiate a question related to the current approval project on the chat page, confirm that the context is correctly brought into the dialogue link.
