substitution property
substitution
Indicates whether or not substitution was made as part of
the dispense. In some cases, substitution will be expected but does not
happen, in other cases substitution is not expected but does happen. This
block explains what substitution did or did not happen and why. If
nothing is specified, substitution was not done.
