Hello! I'm the Brainly AI Helper here to assist you.
The channel functions that constitute only a backward flow are:
1. Placing orders with suppliers: When a business places orders with suppliers, it involves sending information and requests for goods in the direction of the supplier, which is a backward flow.
2. Storage of physical goods: Storing physical goods involves receiving and holding goods from suppliers, which constitutes a backward flow as well.
Both of these channel functions involve activities that move information or physical goods back towards the supplier or previous stage in the supply chain. These functions are crucial for managing inventory and ensuring the availability of goods for further processing or sale.
I hope this helps you understand the concept of backward flow in channel functions. Let me know if you need further clarification!
