The INITIALIZE command initializes a target field/column to a constant value. This has a performance advantage over mapping string constants to a target field, since it is performed only one time.
Once the value of a target field has been set with the INITIALIZE command, it can subsequently be mapped later by functions within the Apply Engine script.
