Dear Customer,

The renewal rule entered in the header will copy into items which are not Completed/Cancelled. It is to alert you, there is at least one line which is completed/cancelled.

The error message appears after you changing the renewal rule but before clicking Save button. However, you are still able to click SAVE and see the success message.

Please follow the resolution steps provided in ##0003416203 - Error "Changing not possible; field is read-only" is Displayed While Updating the Renewal Rule in Contract Header

Thanks & Regards,
