	<GeneralSection><Paragraph>Enterprise Planning uses master plans to maintain planning data in a bucketed fashion.</Paragraph>
		<List><ListIntro>There are three types of master plans:</ListIntro>
			<ListItem><Link href="/baanerp/cp/glossary/glossary#000019" role="glossary">Item master plan</Link>
			</ListItem>
			<ListItem><Link href="/baanerp/cp/glossary/glossary#000020" role="glossary">Channel master plan</Link>
			</ListItem>
			<ListItem><Link href="/baanerp/cp/glossary/glossary#000132" role="glossary">Resource master plan</Link>
			</ListItem>
		</List>
		<Paragraph>In each master plan, planning data is recorded by plan period.</Paragraph>
		<GeneralSection><SectionTitle>Item master plan</SectionTitle>
			<Paragraph>With a few exceptions, you can maintain an <Link href="/baanerp/cp/glossary/glossary#000019" role="glossary">item master plan</Link> for any plan item. If you want to use a <Link href="/baanerp/cp/glossary/glossary#000303" role="glossary">master-planning horizon</Link> and generate a <Link href="/baanerp/cp/glossary/glossary#000073" role="glossary">supply plan</Link> for a plan item, you must maintain an item master plan. If you only use order-based supply planning, the item master plan is optional.</Paragraph>
			<Paragraph>The advantage of an item master plan is that it provides access to several types of master-planning functionality. The disadvantage is that it has an adverse effect on system performance.</Paragraph>
			<List><ListIntro>As a rule, you need an item master plan in the following situations:</ListIntro>
				<ListItem>You want to use a long <Link href="/baanerp/cp/glossary/glossary#000066" role="glossary">planning horizon</Link> for an item (longer than one year), but you do not want to work with <Link href="/baanerp/cp/glossary/glossary#000050" role="glossary">planned orders</Link> over the complete horizon.</ListItem>
				<ListItem>You want to generate forecasts based on demand history, or based on sales budgets.</ListItem>
				<ListItem>You want to maintain an <Link href="/baanerp/cp/glossary/glossary#000011" role="glossary">inventory plan</Link> for the item.</ListItem>
				<ListItem>You want to <Link href="/baanerp/ti/glossary/glossary#Aggregate.ti" role="glossary">aggregate</Link> or <Link href="/baanerp/ti/glossary/glossary#Dissagregate.ti" role="glossary">disaggregate</Link> forecasts, supply plans, or inventory plans.</ListItem>
				<ListItem>You want to use <Link href="/baanerp/cp/glossary/glossary#000037" role="glossary">channel ATP</Link> for the item.</ListItem>
				<ListItem>The item is a <Link href="/baanerp/ti/glossary/glossary#ProducFamily.ti" role="glossary">product family</Link>.</ListItem>
				<ListItem>You want to aggregate the item's <Link href="/baanerp/cp/glossary/glossary#000044" role="glossary">goods-flow</Link> data to a product family.</ListItem>
			</List>
		</GeneralSection>
		<Note><SectionTitle>Note</SectionTitle>
			<Paragraph>You determine whether an item master plan is maintained for an item by means of the <GUIRef href="/baanerp/cp/rpd/cprpd1100m000#cprpd100.osys" role="formfield">Maintain Master Plans</GUIRef> check box in the <GUIRef href="/baanerp/cp/rpd/cprpd1100m000" role="session">Items - Planning (cprpd1100m000)</GUIRef> session. Master-plan functionality is only available for an item if this check box is selected.</Paragraph>
		</Note>
		<GeneralSection><SectionTitle>Channel master plan</SectionTitle>
			<Paragraph>For a particular item/channel combination, you can maintain a <Link href="/baanerp/cp/glossary/glossary#000020" role="glossary">channel master plan</Link>. A channel master plan is comparable to an item master plan, but only contains demand-related data, such as forecast and actual demand, and <Link href="/baanerp/cp/glossary/glossary#000037" role="glossary">channel ATP</Link>.</Paragraph>
			<List><ListIntro>You need a channel master plan in the following situations:</ListIntro>
				<ListItem>You want to maintain demand forecasts by channel</ListItem>
				<ListItem>You want to use <Link href="/baanerp/cp/onlinemanual/000125" role="manual">Channel ATP</Link>
				</ListItem>
			</List>
		</GeneralSection>
		<GeneralSection><SectionTitle>Resource master plan</SectionTitle>
			<List><ListIntro>For a particular resource (work center), you can maintain a <Link href="/baanerp/cp/glossary/glossary#000132" role="glossary">resource master plan</Link>. A resource master plan contains information on:</ListIntro>
				<ListItem>Total available capacity</ListItem>
				<ListItem>Capacity required by various types of activities that are planned and/or carried out in Enterprise Planning, Manufacturing, and Service.</ListItem>
				<ListItem>Free capacity and <Link href="/baanerp/cp/glossary/glossary#000092" role="glossary">capacity CTP</Link>
				</ListItem>
			</List>
			<Paragraph>As a rule, you need a resource master plan for each resource that SSA ERP must take into account during a capacity CTP check.</Paragraph>
