What the data for this category looks like
Residential development yield rate data serves real estate finance scenarios. It is sourced from internal real estate enterprise cost ledgers, housing price data filed with local housing and urban-rural development authorities, and signed payment collection records from sales systems. The data updates once per calendar month. Each single project’s data uses a structured table format. Fields include project unique identifier, total land acquisition cost, allocated engineering construction cost, total marketing and management expenses, total salable housing area, current period signed amount, and cumulative payment received amount. Units are none, ten thousand yuan, ten thousand yuan, ten thousand yuan, square meters, ten thousand yuan, ten thousand yuan respectively.
Constraints on Form and Interaction Workflows
Dispersed data sources require forms to support multi-system field mapping to avoid manual entry errors. Monthly update cycles require form auto-sync intervals to match calendar month periods. Do not set refresh frequencies that are too short. Structured multi-field document formats require forms to support collapsible grouped layouts. Split and organize modules such as total cost and payment collection to avoid page clutter. Differences in custom cost items exist across projects, so forms must provide an entry for custom field configuration. Internal financial attribute data requires forms to bind role permissions, restricting editing and viewing access for unauthorized users.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
recallTopK | Top 8–12 entries | Residential development data has many fields. Too many recalled entries will increase interaction latency; too few will fail to cover complete cost breakdown items |
similarityThreshold | 0.72–0.85 | Need to distinguish cost fields of different projects to avoid confusing data of different projects with the same name |
workflowNodeTimeout | 300 seconds | Pulling cost data across systems requires a longer interface response time |
customFieldEnable | Enabled | Different residential development projects have differentiated cost items such as supporting facilities and municipal allocation costs |
permissionControl | Enabled and configured per project group | Internal financial data requires isolation by project permissions |
autoSyncInterval | 720 hours | Data update rhythm follows the calendar month cycle, matching monthly update requirements |
The parameter values provided on this page are common starting points for configuration. Actual values are affected by material form, data volume, and business rules. Specific issues require specific analysis. It is recommended to test on your own samples before finalizing settings.
Three Common Mistakes
- Phenomenon: A generic error returns when processing the yield rate calculation node in a workflow. The missing business field is not specified. Cause: No dedicated business field validation prompt is configured. Only the default generic error text is used, which cannot match the dedicated data requirements of residential development projects.
- Phenomenon: The embedded frontend iframe form cannot send user-submitted project data to the backend. Cause: FastGPT API callback configuration is not enabled. The backend receiving interface address and verification key are not bound.
- Phenomenon: When voice input is used to enter professional cost terms, the recognition result has deviations or omissions. Cause: No large model system prompt is configured. Recognition rules for business-specific terms are not specified.
How to Confirm Proper Configuration
- Submit single-project test data to confirm the form displays each module’s fields according to preset grouped folding rules.
- Call the bound backend interface to confirm receipt of all custom and standard field data submitted by the form.
- Switch accounts with different roles to verify that permission control rules take effect. Unauthorized accounts cannot edit or view cross-project data.
- Manually trigger a data sync to confirm the sync interval matches the monthly update rhythm, with no abnormal delays.
