	<GeneralSection><List><ListIntro><Link href="/baanerp/cp/glossary/glossary#000059" role="glossary">Master planning</Link> is a planning concept that has the following aspects:</ListIntro>
			<ListItem>A method to maintain planning data (in a bucketed fashion)</ListItem>
			<ListItem>A method for supply planning (by generating a supply plan)</ListItem>

		<GeneralSection><SectionTitle>Master-planning view</SectionTitle>
			<List><ListIntro>Master planning works with the following types of master plans:</ListIntro>

				<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 these master plans, planning data is maintained over a planning horizon, which is divided into time buckets or <Link href="/baanerp/cp/glossary/glossary#000109" role="glossary">plan periods</Link>.</Paragraph>
			<Paragraph>The length of these plan periods can vary. You can use periods with a fixed length throughout the planning horizon, but you can also use shorter periods (for example, days or weeks) for the immediate future and longer periods (for example, months) for longer-term planning.</Paragraph>
			<Paragraph>Master-plan functionality is available for items, item/channel combinations, and resources for which you maintain a master plan. This is true for the whole planning horizon, even if you do not use master planning for supply planning.</Paragraph>

			<List><ListIntro>During a master-plan simulation, supply is planned in the form of a <Link href="/baanerp/cp/glossary/glossary#000073" role="glossary">supply plan</Link>. You can carry out a master-plan simulation in the following sessions:</ListIntro>

				</ListItem>
			</List>
			<List><ListIntro>For the supply plan, three sources of supply are used: production, purchase, and distribution (from another warehouse location in the same company, or from a related company). Accordingly, the item master plan contains the following supply plan fields:</ListIntro>
				<ListItem><Link href="/baanerp/cp/glossary/glossary#000018" role="glossary">Production plan</Link>
				</ListItem>
				<ListItem><Link href="/baanerp/cp/glossary/glossary#000023" role="glossary">Purchase plan</Link>
				</ListItem>
				<ListItem><Link href="/baanerp/cp/glossary/glossary#000049" role="glossary">Planned distribution orders</Link> (generated outside the order horizon)</ListItem>
			</List>
			<Paragraph>Enterprise Planning can compute these plans during a master-plan simulation. Alternatively, you can directly enter (or modify) production-plan volumes or purchase-plan volumes in the item master plan.</Paragraph>
			<List><ListIntro>For the production plan, Enterprise Planning uses:</ListIntro>
				<ListItem><Link href="/baanerp/ti/glossary/glossary#000081" role="glossary">Bills of critical materials</Link> to explode critical material requirements</ListItem>
				<ListItem><Link href="/baanerp/ti/glossary/glossary#BillOfCritic.ti" role="glossary">Bills of critical capacities</Link> to calculate lead times and to determine the necessary critical resource capacity</ListItem>

			<Paragraph>In infinite planning, it is assumed that there are no serious constraints on the availability of components and capacity. Therefore, no constraints are taken into account. For more information, see <Link href="/baanerp/cp/onlinemanual/000142" role="manual">Infinite master planning</Link>.</Paragraph>
			<Paragraph>In workload control, material constraints and/or capacity constraints do play a role. Based on the idea that the workload on the shop floor significantly affects the <Link href="/baanerp/tc/glossary/glossary#000010" role="glossary">order lead time</Link>, this method aims at controlling and leveling the amount of workload. For more information, see <Link href="/baanerp/cp/onlinemanual/000003" role="manual">Workload control</Link>.</Paragraph>
			<Paragraph>By default, Enterprise Planning carries out infinite planning. If you want to use workload control, you must assign the items involved to a <Link href="/baanerp/cp/glossary/glossary#000004" role="glossary">plan unit</Link>, and set its master-planning engine to <GUIRef href="/baanerp/cp/domains/rpd.plme#workloadcontrol" role="enum">Workload Control</GUIRef>.</Paragraph>
