# Input data

This zone brings the **required input data** into the project and standardizes where it is stored so downstream steps can run reliably. It synchronizes the raw inputs into managed datasets used by the rest of the Flow.

## What this zone supports

- Building a clean and consistent **orders history** dataset for spend & performance analysis
- Preparing the inputs required to create an **open-orders** view for prediction
- Enabling optional enrichment with **duty/tariff** information (if provided)

## Main objects

### Inputs
- `input_supplier_orders`  
  Source dataset (or folder-backed dataset) containing purchase order and delivery history.

- `Updated_duty_tariffs`  
  Optional enrichment input containing duty/tariff information to join later with orders.
