To automate form field calculations in YiDa, enable formulas in field properties and use the {#{fieldId}} reference syntax to trigger automatic calculations and default value population. This approach handles default values, field validations, and cross-field rules.

Field references in low-code form formulas require the {#{fieldId}} syntax. Formulas must also use uppercase function names and English punctuation to properly execute default values, validations, and cross-field business rules.

Yes, you can set default values for date, text, and number fields using business rules. By configuring formulas directly on these fields, the form auto-populates values, reducing manual data entry and ensuring consistency.

You add field validation to a form by applying custom validation formulas to the target fields. These formulas execute during submission to enforce business rules and ensure data accuracy before the form is accepted.

Limitations of using formulas for cross-field calculations include strict syntax requirements: functions must be uppercase, punctuation must be English, and field references must use the {#{fieldId}} format, which may require precise adherence to avoid errors.
