This transformer is predominantly used when there is a requirement of copying objects to another key.
Here’s how you can implement the transformer.
Step 1: Click on Add Data Transformer and select the Copy Using A Pattern transformer.
Step 2: You have to select the Pattern (origin key) first.
Step 3: Next, you have to select the Replacement (copy destination). The best part is that you can copy multiple objects while implementing this transformer. All you need to do is utilize the * notation after the variable in the field of Pattern and $1 notation after the copy destination in the Replacement field.
Step 4: If you click on the Run Test button, you will see that the transformer has copied the objects to the destination key (provided in the Replacement field).
