How can we create Data Subflow and explain how it will work in while execute design?

We have to create data sub flow with same logic which we want to implement in data flow after we have to create data flow with multiple sources. We can drag subflow transformation in data flow and connect to all sources, execution will success by apply logic on each source and data will load. We see in detail explanation with an example

Example:

I have crated preview of data flow in Tera data data sub flow with simple logic using transformations which i want to implement in data flow

I have created teradata data flow and drag multiple sources, connect each source to sub flow which is having my logic and connected to target and executed. We can reuse same sub flow at all sources as see in below
