Form and Interaction for Building Construction Project Yield

What the data for this category looks like

Data related to building construction project yield rates mainly comes from project cost ledgers, monthly progress payment vouchers, cost consulting reports, and client settlement documents. The data update schedule aligns with construction node cycles, and is typically updated after each structural layer completion, facade construction completion, or monthly settlement node. Each record corresponds to single-node data for one construction section. The document structure includes fields such as project unique identifier, section code, node name, current period input cost, current period settlement revenue, total cumulative input cost, and total cumulative settlement revenue. The unit of measurement for construction quantities is square meters or cubic meters, and monetary amounts are denominated in yuan.

Constraints imposed by these characteristics on form and interaction

Building construction project data is uniquely identified by construction section and node, which requires the form to be configured with unique validation rules to avoid duplicate entries. Data requires batch import of monthly node information for multiple construction sections, so the form must support batch entry and nested sub-forms to adapt to the entry requirements of detailed sub-items. The fixed data update cycle requires the form to support saving reusable templates to reduce repeated configuration costs. Fields include amount and measurement data with different units, so the form must support automatic unit matching validation to reduce input errors. Additionally, data must be associated with subsequent knowledge base retrieval, so form fields can be passed as retrieval parameters to achieve precise matching.

How to set the configurations

Configuration Item	Recommended Setting	Rationale
`formUniqueField`	Bind the combination of `projectId` and `nodeCode`	Ensure that data for a single construction section and single node is not entered repeatedly, matching the unique identification rules for building construction project data
`subFormMaxLevel`	2	Adapt to the entry of secondary detailed sub-items for input and revenue, avoiding excessive levels that increase operation costs
`batchInputMaxSize`	50 entries per batch	Match the business scenario of monthly batch import of multi-section node data, balancing import efficiency and system stability
`inputUnitAutoMatch`	Enabled, linked to preset unit fields	Automatically validate the unit format of amounts and measurement quantities, reducing the error rate of manual input
`formTemplateSaveEnable`	Save templates according to monthly node cycles	Reuse entry configurations for fixed cycles, adapting to the rhythm of updating data by node for building construction projects
`formVariablePassEnable`	Enabled, map form fields as retrieval parameters	Adapt to the variable passing logic of v4.8.7 and above versions, ensuring that form fields can be passed as retrieval parameters to the knowledge base retrieval link

The parameter values provided on this page are all conventional recommendations used as starting points for configuration. Actual values are affected by material forms, data volume, and business rules. Specific issues require specific analysis, and it is recommended to test on your own samples before finalizing.

Three Common Configuration Errors

Symptom: Custom variables entered in the form cannot be passed to the subsequent knowledge base retrieval link, resulting in empty retrieval results. Cause: The formVariablePassEnable configuration is not enabled, and form fields are not mapped as retrieval parameters.
Symptom: Multiple sets of detailed sub-item data submitted in a single form cannot generate matching vector retrieval results, and the recalled content is unrelated to the input. Cause: The subFormVectorBind rule is not configured, and vectors are only generated for main form fields, excluding detailed sub-form data.
Symptom: Switching the knowledge base based on user-entered project information fails, and preset default knowledge base results are always returned. Cause: The knowledge base switching rule based on form fields is not configured, and only fixed knowledge base call configurations are used.

How to Verify the Configuration is Complete

Submit test data with duplicate projectId and nodeCode, check whether the system triggers unique validation interception.
After entering sub-form detailed sub-item data, view the vector generation preview interface to confirm that sub-form fields are included in the vector generation scope.
Set different form field values to trigger knowledge base retrieval, check whether the retrieved knowledge base adjusts according to the field values.
Save the current form configuration as a template, create a new entry page, check whether the template configuration is automatically loaded completely.
