If a required field has no data entered or there are any other such data entry-related issues when you try to save a record, the error message "Cannot save the record because of error(s) in the following input data." will appear.
Below the error message, there will be a list of the fields (item names) that need to have their input value corrected.

Check the error details displayed below each field that has an issue, and update the input values as needed.
For information on how to resolve the errors that may be displayed, refer to the following section.

If "(Cannot display the item name)" appears in the error message, it may be because you do not have permission to view the field in which an error was detected.
In order to solve the error, you need to ask an app administrator to check the settings of the app.
For details on how to resolve the issue, see the following page.

If the field name mentioned in the error message is not found on the screen to edit or add a record, there is a possibility that the field name is hidden. Look for the field with error details displayed below it, and modify the input value.

If you cannot find the field with error details, there is a possibility that the field is temporarily hidden due to customization using an API or a plug-in.
Ask an app administrator to check if there are any problems in the app's customization or plug-in settings.

Note that, even if a field name is set to be hidden on the app form, the field name will be used for error messages and filter settings. For this reason, make sure to assign a field name that is easy to identify.

See below for solutions to the errors that are displayed below fields.

If this error appears, it means the field cannot be left empty and needs to be filled in.

If your kintone display language is set to English, dates need to be in the "month/day/year" format, with slashes used as separators (e.g., 06/05/2020). If your display language is set to Japanese, dates need to be in the "year-month-day" format, with hyphens used as separators (e.g., 2020-06-05).

Times need to be entered either with the 12-hour clock format (e.g., 05:25 PM) or the 24-hour clock format (e.g., 17:25), depending on which format you are using.
