-- the add icon can be used to add a new accrual plan.

-- the delete icon can be used to remove a particular accrual plan from your system.  

Note that due to referential integrity constraints, you can often not delete a record if it is being referenced elsewhere in the system.  In particular, you will not be allowed to delete an accrual plan if it has had accrual amounts posted to it.  When deleting an accrual plan, it will also remove associated entries (including user associations to that plan, associated assignments, associated schedules, etc.).

-- the edit icon can be used to modify a record.  Note that in most instances, double clicking on a row will provide the same behavior as clicking the edit icon.
