Ledger Summary and Report Generation for Engineering Construction Project Approval: Workflow Orchestration

Ledger Summary and Report Generation for Engineering Construction Project Approval: Workflow Orchestration This document is based on FastGPT v4.17.0.

Reference only; verify against the target FastGPT release and deployment documentation.

What this category of data looks like

Data for this category comes from engineering construction project approval management systems, construction drawing review systems, enterprise qualification databases, and credit platforms. The update frequency is daily. Daily documents include construction permit applications, construction drawing review qualification certificates, quality and safety supervision procedures, completion record forms, and more. Data fields cover project unique identifiers, participating unit qualification information, approval node status, processing time limit nodes, and other details. Some documents contain multimodal construction drawing attachments. The data structure changes with the approval process, and required fields vary across different stages.

What constraints do these characteristics impose on workflow orchestration

Data sources are scattered and updated daily. Workflow orchestration must support sequential scheduling of data pulls from multiple systems to avoid repeated pulls of expired data. Daily documents include multimodal attachments and structured fields. Workflows must include separate node configurations for structured field extraction and multimodal content parsing. Variations in required fields across approval stages require workflows to support branch judgment, to automatically adapt to corresponding data validation rules for different approval nodes. The daily data update frequency requires workflow scheduled trigger intervals to match the daily update rhythm, to avoid ledger data lag caused by overly long pull intervals.

How to set configurations

Configuration ItemRecommended SettingRationale
Chunk Length800–1200 charactersMatches the structured field and text content length of daily documents, avoids overly fragmented or overly long chunks that reduce extraction accuracy
Single Search LimitTop 6 entriesMatches the number of associated documents per project for engineering construction project approval data, avoids redundant results
variables configurationBind project numbers and approval node identifiersEnables cross-node data transfer and conditional judgment within workflows, adapts to field requirements for different approval stages
nodeId configurationAssign unique node identifiers by approval stageFacilitates workflow debugging and abnormal node localization, matches the sequential logic of multi-system data pulls
Timeout Setting600 secondsMatches the average response time for multi-system data pulls, avoids workflow interruptions caused by network delays
Scheduled Trigger IntervalOnce dailyMatches the daily data update frequency, avoids pulling expired or unupdated data
Branch Trigger RuleTrigger corresponding nodes by approval node typeAdapts to field validation and document processing requirements for different stages

Three common mistakes

  • Phenomenon: Multimodal attachments and plain text requests in workflows are not assigned to corresponding processing nodes by type, leading to plain text requests calling multimodal models and incurring additional costs. Cause: No content type judgment branch is configured in the workflow, and the input data type stored in variables is not distinguished.
  • Phenomenon: The number of search results returned by the knowledge base in the workflow is far lower than expected, with only 3 or fewer entries returned. Cause: The single search limit configuration value is not adjusted, the default low limit parameter is retained, and the multi-document association requirement for engineering construction project approval is not matched.
  • Phenomenon: Workflow nodes designed for plain text queries trigger document parsing processes, leading to processing delays. Cause: The automatic document parsing switch in workflow nodes is not turned off, and ordinary text input is mistakenly treated as a document attachment for processing.

How to confirm correct configuration

  • Manually trigger the workflow, input structured data and attachments for a single project, and verify that fields passed between nodes via variables are complete and accurate.
  • View workflow run logs, confirm that nodes corresponding to nodeId trigger in approval stage order, with no abnormal interruptions.
  • Adjust the single search limit configuration, trigger a search action, and verify that the number of returned results matches the configured value.
  • Simulate scenarios with multimodal attachments and plain text input, confirm that the workflow automatically enters the corresponding processing branch.
