	<GeneralSection><List><ListIntro>When SSA ERP determines the required inventory level for order-based planning, it takes the following data into account:</ListIntro>
			<ListItem>Safety stock</ListItem>
			<ListItem>Inventory plan</ListItem>
		</List>
		<Paragraph>You can define the <Link href="/baanerp/wh/glossary/glossary#000377" role="glossary">safety stock</Link> in the <GUIRef href="/baanerp/tc/ibd/tcibd2500m000" role="session">Items - Ordering (tcibd2500m000)</GUIRef> session. In the same session, you can define a <Link href="/baanerp/tc/glossary/glossary#SeasonPatter.tc" role="glossary">seasonal pattern</Link> for safety stock.</Paragraph>
		<Paragraph>You can define the <Link href="/baanerp/cp/glossary/glossary#000011" role="glossary">inventory plan</Link> in the <GUIRef href="/baanerp/cp/rmp/cprmp2101m000" role="session">Item Master Plan (cprmp2101m000)</GUIRef> session. You can also generate the inventory plan (see <Link href="/baanerp/cp/onlinemanual/000114" role="manual">Inventory planning in Enterprise Planning</Link> ).</Paragraph>
		<Paragraph>If the item has a master plan, the inventory plan determines the required inventory level. However, the inventory level in the first simulated period must be at least equal to the safety stock.</Paragraph>
		<Paragraph>If the item has no master plan, the required inventory level in each plan period is equal to the safety stock.</Paragraph>
