	<AimSection><Paragraph>SSA ERP uses <Link href="/baanerp/tc/glossary/glossary#000306" role="glossary">unit effectivity</Link> in order planning to support interchangeability of units. If a unit is interchangeable, SSA ERP can use it to meet requirements of a unit with the same configuration.</Paragraph>

	<GeneralSection><Paragraph>This topic gives an example of a situation in which SSA ERP uses the inventory of an interchangeable unit to cover demand of an other unit.</Paragraph>

		<Paragraph>In week 12, the following requirements and receipts exist for item X:</Paragraph>
		<TABLE border="1"><THEAD><TR><TD>Day</TD>
					<TD>Required quantity unit 101</TD>

		</TABLE>
		<Paragraph>The projected inventory on day 1 is as follows:</Paragraph>
		<List><ListItem>Unit 101: 8</ListItem>
			<ListItem>Unit 102: 0</ListItem>
		</List>
	</ExampleSection>
	<GeneralSection><SectionTitle>Interchangeable</SectionTitle>
		<Paragraph>If units 101 and 102 are interchangeable, the inventory and the firm-planned receipts can be used for both units. In other words, no planned order need be generated in this situation. The firm-planned receipt on day 4 must be rescheduled to day 3: SSA ERP indicates this in a <Link href="/baanerp/ti/glossary/glossary#RescheMessag.ti" role="glossary">rescheduling message</Link>.</Paragraph>
	</GeneralSection>
	<GeneralSection><SectionTitle>Not interchangeable</SectionTitle>
		<Paragraph>If units 101 and 102 are not interchangeable, SSA ERP generates:</Paragraph>
		<List><ListItem>A rescheduling message for the firm-planned receipt on day 4 (reschedule to day 2).</ListItem>
			<ListItem>A planned order for unit 101 on day 3.</ListItem>
			<ListItem>Possibly, a planned order for unit 101 on day 5 (depending on the lot-size rules and the order interval).</ListItem>
