Schedules cannot be edited, but you can create a new schedule, apply it to transactions using mass update, and delete the obsolete schedule. The application will not allow you to delete a schedule if it has depending records (transactions, categories, or subcategories). Make sure all transactions based on the original schedule have been edited or deleted. You must also modify any Category Configuration and/or Subcategory Definition that refers to the schedule to delete.
Choose Administration | Schedules.
Select the schedule to delete.
Click Delete.
Choose OK.
