	<GeneralSection><Paragraph>An engineering bill of material (EBOM) describes the relationships of components to their parent items in the same way that a <Link href="/baanerp/ti/glossary/glossary#BillOfMateri.ti" role="glossary">production</Link> bill of material (PBOM) does. The main difference between an EBOM and a PBOM is that rather than having a <Link href="/baanerp/ti/glossary/glossary#SequenNumber.ti" role="glossary">sequence number</Link> to take account of items valid on different dates, EBOMs use different <Link href="/baanerp/ti/glossary/glossary#Revision.ti" role="glossary">revisions</Link> of E-items.</Paragraph>
		<GeneralSection><SectionTitle>Copying an EBOM</SectionTitle>
			<List><ListIntro>A single-level EBOM can be copied to a single-level PBOM by one of the following three methods:</ListIntro>
				<ListItem><GUIRef href="/baanerp/ti/domains/edm.updm#all.lines" role="enum">All Available Lines</GUIRef>. All PBOM lines expire and are replaced by the EBOM lines and non-EBOM lines. Non-EBOM lines are lines from a non-project PBOM that are copied to a project. See the copy method <GUIRef href="/baanerp/ti/domains/edm.cpmt#copy.std.cust" role="enum">NonProj Item to Proj Item</GUIRef>.</ListItem>
				<ListItem><GUIRef href="/baanerp/ti/domains/edm.updm#corresponding" role="enum">Only Corresponding Pos.</GUIRef>. Lines in the PBOM whose line numbers match the line numbers in the EBOM are replaced by the corresponding EBOM lines and non-EBOM lines. The other PBOM lines remain unchanged.</ListItem>
				<ListItem><GUIRef href="/baanerp/ti/domains/edm.updm#previous.linked" role="enum">Corresp. and Linked Pos.</GUIRef>. Both lines in the PBOM whose line numbers match the EBOM line numbers, and lines which do not match but have been created by previous finalizing actions performed on engineering data (the <GUIRef href="/baanerp/ti/bom/tibom1110m000#tibom010.ledm" role="formfield">Link with EDM</GUIRef> check box in the <Link href="/baanerp/ti/bom/tibom1110m000" role="session">Bill of Material (tibom1110m000)</Link> session is selected, are replaced by the EBOM lines and non-EBOM lines.</ListItem>
			</List>
			<Paragraph>The other lines from the PBOM remain unchanged. These unchanged lines are not engineering-related. An example of one of these lines could be packing materials. In this way, you can make a clear distinction in production BOMs between engineering-related components and logistics components that do not relate to engineering.</Paragraph>
			<List><ListIntro>If you copy the EBOM to the PBOM, the expiry date of the PBOM component is filled by either:</ListIntro>
				<ListItem>The effective date of the revision for the parent E-item from the EBOM.</ListItem>
				<ListItem>The effective date of the PBOM line, if it expires later.</ListItem>
			</List>
			<List><ListIntro>The effective date of the PBOM line expires later than that of the EBOM line if:</ListIntro>
				<ListItem>A line is removed from the PBOM.</ListItem>
				<ListItem>A line is replaced by a line from the EBOM, and the <GUIRef href="/baanerp/ti/edm/tiedm0100m000#tiedm000.pbhs" role="formfield">PBOM History</GUIRef> check box in the <Link href="/baanerp/ti/edm/tiedm0100m000" role="session">Engineering Data Management Parameters (tiedm0100m000)</Link> session is selected.</ListItem>
			</List>
			<Paragraph>To include the line from the EBOM, a new serial number is created for the line in the PBOM.</Paragraph>

			<Paragraph>An EBOM's parent item is a particular <Link href="/baanerp/ti/glossary/glossary#Revision.ti" role="glossary">revision</Link> of an E-item. The components can be items or E-items.</Paragraph>
			<List><ListIntro>When you copy a component from an EBOM to a PBOM, you can use the <GUIRef href="/baanerp/ti/edm/tiedm1120m000" role="session">EBOM Copy Data (tiedm1120m000)</GUIRef> session to define one of the following copy methods:</ListIntro>

				<ListItem>No components are copied. <List><ListIntro>This occurs in the following circumstances:</ListIntro>
						<ListItem>The units of the components in the Component and To Item fields do not match.</ListItem>
						<ListItem>There is no valid released revision of the E-item.</ListItem>

				<ListItemHead>Question 3</ListItemHead>

					</List>
				</ListItem>
				<ListItemHead>Question 5</ListItemHead>

			<List><ListIntro>When searching for items using relationships defined in <GUIRef href="/baanerp/ti/edm/tiedm1100m000" role="session">Engineering Item Revision (tiedm1100m000)</GUIRef> session, SSA ERP uses the following rules:</ListIntro>
				<ListItem>When data is copied to a project, relationships with project items take priority over relationships with non-project items.</ListItem>
				<ListItem>When data is not copied to a project, only relationships with non-project items apply.</ListItem>
			</List>
			<List><ListIntro>When searching for relationships, the following priorities apply:</ListIntro>
				<ListItem>relationships created by, or used in, copying from an EBOM have priority over relationships created by, or used in, copying an E-item to an item.</ListItem>
				<ListItem>Relationships created by, or used in, copying an E-item to an item have priority over relationships not used in copying.</ListItem>
