Mapping a source column
Use the Column Map Editor to map a source column to a target.
Source and target columns with the same name and compatible data types
are automatically mapped.
Applying a classification
Use the Classification column in
the Column Map Editor to apply a classification to a source column
in the map. If a source column uses a masking policy, the map will
use the policy as the default classification type.
Working with column map procedures A column map procedure is a procedure that
is used to mask or transform the data in a column when you run a service.
As the name indicates, you must add column map procedures to a column
map. You can write column map procedures by using the Lua scripting
language.
