	<AimSection><List><ListIntro>You can maintain handling units with all statuses in all stages of the inbound flow, storage, or outbound flow, except for the following:</ListIntro>
			<ListItem>The handling unit is dormant and has the <GUIRef href="/baanerp/wh/domains/hust#inactive" role="enum">Inactive</GUIRef> status. However, you can link handling units to empty inactive handling units. As a result, the inactive handling unit becomes the parent and obtains the status of the handling unit that you linked. You can link other handling units to this parent if their statuses match the status of the parent.</ListItem>
			<ListItem>The handling unit has the <GUIRef href="/baanerp/wh/domains/hust#rejected" role="enum">Rejected</GUIRef> status.</ListItem>
			<ListItem>The handling unit is ready for shipment and has the <GUIRef href="/baanerp/wh/domains/hust#shipment.frozen" role="enum">Shipment Frozen</GUIRef> status.</ListItem>
			<ListItem>The handling unit has left the warehouse and has the <GUIRef href="/baanerp/wh/domains/hust#shipped" role="enum">Shipped</GUIRef> status.</ListItem>
			<ListItem>The handling unit is being transferred to another warehouse and has the <GUIRef href="/baanerp/wh/domains/hust#transit" role="enum">In Transit</GUIRef> status.</ListItem>
			<ListItem>The handling unit is no longer in use and has the <GUIRef href="/baanerp/wh/domains/hust#closed" role="enum">Closed</GUIRef> status.</ListItem>
		</List>

	<GeneralSection><Paragraph>Note that you cannot link handling units with different statuses.</Paragraph>
		<Paragraph>If any of these exceptions apply to a handling unit, the handling unit maintenance commands are unavailable. If you use the drag-and-drop functionality in the <GUIRef href="" role="manual">Tree Structure</GUIRef> to move handling units, messages appear if a particular action is unavailable.</Paragraph>
		<Paragraph>Linking and unlinking handling units can affect the underlying structure of advice lines or shipments. You cannot link handling units that are advised to different locations. Modifying handling unit structures for handling units linked to shipments and shipment lines results in the following:</Paragraph>
		<List><ListTitle>Handling units and shipments</ListTitle>
			<ListItem>If you move a child handling unit to another parent, the shipment line linked to the child handling unit is linked to the shipment header of the new parent and removed from the shipment header from which the child handling unit was moved.</ListItem>
			<ListItem>If you link a handling unit linked to a shipment line to an empty, inactive handling unit, the inactive handling unit becomes the parent, and SSA® ERP LN generates a shipment for the parent handling unit. The data for the new shipment are copied from the shipment from which the shipment line/child handling unit was removed.</ListItem>
			<ListItem>If you move all child handling units/shipment lines from a parent/shipment, the shipment linked to the parent handling unit is deleted.</ListItem>
		</List>
