# Transfer Requirement

:lock: TransferRequirement.**Show**

A **Transfer Requirement** is a list that specifies quantity demands for **Products** (Material Definitions) that are required by a storage or production system. It groups a list of **products** and quantities that must be transferred from one *Storage Area* to another *Storage Area* or a **Resource**.

!!! note
	The transfer requirement list may contain duplicate products.

## Transfer Requirement Lifecycle

A **Transfer Requirement**, during its life cycle, follows the state model as illustrated in the next picture.

```

The lifecycle is further described in the table below. Note that there will be some release options that will control the options and degree of tracking that is required. For example, a transfer requirement can be marked to support partial releases and can also be considered automatically delivered after picking thus skipping the need for an explicit transfer order.

| State | Description |
|--|-----|
| **Requested** | The Transfer Requirement has been requested |
| **Approved** | The Transfer Requirement has been approved (transfer requirements cannot be further be modified at this point) |
| **Released** | All required quantity has been released |
| **Picked** | All required quantity has been picked |
| **In Transport** | All required quantity is assigned to a transport order |
| **Delivered** | All required quantity has been delivered |
| **Closed** | All required quantity has been delivered and necessary individual packaging units created |
| **Canceled** | The Transfer Requirement has been canceled |
