Data Visibility in Child Tables
Switch to Un-editable Grid
If you wish to display more values in the preview of the Quotation Item table, you can opt to deactivate the Editable Grid for the Quotation Item DocType.
Once the Editable Grid feature is turned off for the Quotation Item, the values will be presented in a preview format within the Quotation Item table.
To ensure that a particular field’s value appears in the preview, ensure that for that specific field, the “In List View” property is enabled within the Customize Form tool.
