Default values and required settings
Default value
The mobile phone field supports default values, but the default value can only be a mobile or phone type field from another object through a lookup relationship. Fixed text input or formula input is not supported.
[!NOTE] The default value is auto-filled when creating a new record in the front end. Users can modify it after pre-filling. After modifying the default value configuration, historical data is not recalculated.
Required configuration
- Field-level required: On the field configuration page, set “Required” to “Yes”. This applies across all scenarios (front-end entry and back-end import). Missing values prevent saving.
- Layout-level required: If the field is required only in specific business scenarios, set it as not required in the field properties. Then, in the specific page layout editor, check “Required”.
- Conditional required: If the required condition depends on the value of another field, configure validation rules.
Usage limitations
- The mobile phone field does not support formula-based default values.
