Select custom mode to define a parsing operation that uses one or more dictionary steps or regular expression steps.
You can create multiple steps in a single parse asset. At run time, the Parse transformation runs the steps that you specify.
Note: The Parse transformation runs any dictionary step in an asset before it runs any regular expression step. First, the transformation runs the dictionary steps in the order in which they appear in the step sequence. Next, the transformation runs the regular expression steps in the order in which they appear in the step sequence.
