An accounting mistake in which an entry is recorded in the
incorrect account, violating the fundamental principles of
accounting. An error of principle is a procedural error, meaning
that the value recorded was the correct value but placed
incorrectly. For example, a company may record personal expenses as
business expenses. An error of principle is different than failing
to record the item in question ("error of omission"), or recording
the wrong value in the correct account ("error of commission").
These errors are referred to as input errors.
