Here is an overview of some key ANSI X12 transactions used in the supply chain sector, with a step-by-step flow through logistics and warehouse processes:


### 1. 850 Purchase Order

   - Step 2: The supplier receives the purchase order and begins processing it.


### 2. 855 Purchase Order Acknowledgment

   - Step 1: The supplier sends an 855 Purchase Order Acknowledgment back to the retailer to confirm receipt and acceptance of the purchase order.
