Long text
Overview
The long text field addresses scenarios where the 2,000-character limit of the multi-line text field is insufficient, such as contract terms and lengthy remarks. This field provides greater text capacity but cannot be used as a filter condition for roll-up summary fields or lookup relationship fields. Consider future filtering and aggregation needs before configuring this field type.
Basic specifications
| Attribute | Description |
|---|---|
| Applicable scenario | Lengthy descriptions, contract terms, extensive remarks, etc. |
| Capacity | Exceeds the 2,000-character limit of multi-line text |
Configuration highlights
- The long text field is similar to multi-line text but supports greater character capacity.
- Supports basic attributes such as default values and help text.
Default values and required settings
Default value
Long text fields support the following default value methods:
- Fixed text: Enter a text string as the default value.
- Formula: Use a formula to dynamically generate the default value, such as inserting global variables or system variables.
[!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 a default value formula, 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
- Long text fields cannot be used as filter conditions for roll-up summary fields or lookup relationship fields.
- Long text fields cannot be used as operands in formula fields.
