Working with Ordinal Categorical Arrays
In order to combine or compare two categorical arrays, the sets of categories for both input arrays
must be identical, including their order. Furthermore, ordinal categorical arrays are always
protected. Therefore, when you assign values to an ordinal categorical array, the values must belong
to one of the existing categories. For more information see “Work with Protected Categorical Arrays”
on page 8-30.
