### **General description**

The Copy using a pattern Transformer takes a part of the entity data and copies it. This can be useful, for example, when only a shipping address is given but no additional billing address. If a target API requires both, the Copy using a pattern Transformer can be used to duplicate the data across both required fields.

### **The different parts of the Copy using a pattern Transformer**

- **Pattern (required field)**  
This is the path towards the entity data that needs to be copied.

- **Replacement** **(required field)**  
This is the output location where the copied data will be added.

- **Conditions**  
This ensures that it copies the data only when a certain condition is met. For example, when a box is checked to confirm that the billing and shipping are the same address.
