This article provides important notes on changing process management settings and solutions to related errors.

Even if you disable process management, the statuses of existing records and the history of status changes will remain.
However, disabling the feature will delete permission settings and record filter settings where assignees are set as a filter condition.

If you enable process management again, each record will be restored to the status it had just before the feature was disabled.

Check the cause and solution below for the error message that appears.

Only statuses that are currently not applied to any records can be deleted.
It is not possible to use a status name if it has already been used for an existing or deleted status.

When you try to delete a status that is currently applied to one or more records, the following error message will appear.

If this error appears, you will be able to delete the relevant status after deleting the records it is applied to or changing the statuses of those records.

The following precautions should be taken when changing assignee settings.

Changing your assignee settings will not change the assignees already set for existing records.
If there are records for which the assignee needs to be changed, an app administrator needs to make the changes individually.

It will no longer be possible to change the status of records for which the deactivated user is specified as the current assignee.
If an app administrator changes the current assignee to a user who can currently use kintone, it will be possible to change the status again.

You cannot change the assignee selection method (User chooses one assignee from the list to take action, All assignees in the list must take action, or One assignee in the list must take action) if the status you want to change the assignee selection method for is currently applied to one or more records.
If you try to change the assignee selection method in such a case, the following error message will appear.

If this error message appears, you can change the assignee selection method after performing one of the following actions.

• Delete the records that have the relevant status
• Change the statuses of the records that have the relevant status
• Go to the Record details screen of the records that have the relevant status, click Change assignee, and delete all of the current assignees.

Even if you re-configure the settings for an action, the statuses of existing records will not change.

An action cannot be deleted if both of the following conditions apply.

• There are existing records with the status for which the relevant action can be performed.
• The records mentioned above will have no other actions available if the relevant action is deleted.

An error message may appear when you try to update an app after changing the process management settings.

If a record with the status that you made changes to is created and an assignee is specified before you update the app with your changed settings, the following error message will appear when you click Update app.

If you delete a status and a new record with that status is created before you update the app, the following error will appear when you click Update app.

In both of the cases above, you will be able to change the process management settings after the relevant records are deleted or have their statuses changed.

If you try to delete a field that is being used to specify a process management assignee, the following error message may appear.

This error occurs because the field you are trying to delete is set as an assignee in the Process management settings.
Open the Process management settings and remove the target field from Assignee list, then delete the field on the app form.

For example, if this error message appears when you try to delete an "Approver" field, you need to go to the Process management settings and delete "Approver" from Assignee list under 3. Process flow settings.
The "Approver" field can then be deleted from the app form.
