	<GeneralSection><Paragraph>Each <Link href="/baanerp/cp/glossary/glossary#000371" role="glossary">signal</Link> is a token of a certain signal type. Signal types, in turn, belong to broader categories of signal types.</Paragraph>
		<GeneralSection><SectionTitle>Types and categories</SectionTitle>
			<List><ListIntro>The following categories of signal types can be distinguished:</ListIntro>
				<ListItem>Inventory and demand signals</ListItem>
				<ListItem>Order signals</ListItem>
				<ListItem>Resource signals</ListItem>
				<ListItem>Error signals</ListItem>
			</List>
			<Paragraph>Resource signals are stored and retrieved per resource. You can view and print resource signals in the <GUIRef href="/baanerp/cp/rao/cprao1130m000" role="session">Resource - Signals (cprao1130m000)</GUIRef> session and the <GUIRef href="/baanerp/cp/rao/cprao1430m000" role="session">Print Signals by Resource (cprao1430m000)</GUIRef> session, respectively.</Paragraph>
			<Paragraph>All other signals fall under the generic label of item signals, because they are stored and retrieved per item. You can can view and print item signals in the <GUIRef href="/baanerp/cp/rao/cprao1125m000" role="session">Planner/Item Signals (cprao1125m000)</GUIRef> session and the <GUIRef href="/baanerp/cp/rao/cprao1425m000" role="session">Print Signals by Item/Planner (cprao1425m000)</GUIRef> session, respectively.</Paragraph>
			<List><ListIntro>Although all error signals are considered as item signals, some types of error signals do not refer to a specific item. For these signals the item field remains empty. This holds true for the following error signal types:</ListIntro>
				<ListItem><GUIRef href="/baanerp/cp/domains/rao.sign#fatal" role="enum">Fatal Error</GUIRef>
				</ListItem>
				<ListItem><GUIRef href="/baanerp/cp/domains/rao.sign#empty.plan.unit" role="enum">No Items for Plan Unit</GUIRef>
				</ListItem>
			</List>
		</GeneralSection>
		<Note><SectionTitle>Note</SectionTitle>
			<List><ListIntro>The following item signals can also be generated for <Link href="/baanerp/tc/glossary/glossary#000016" role="glossary">channels</Link>:</ListIntro>
				<ListItem><GUIRef href="/baanerp/cp/domains/rao.sign#actual.to.late" role="enum">Actual Demand Late</GUIRef>
				</ListItem>
				<ListItem><GUIRef href="/baanerp/cp/domains/rao.sign#demf.dif.act" role="enum">Forecast &lt;&gt; Actual Demand</GUIRef>
				</ListItem>
				<ListItem><GUIRef href="/baanerp/cp/domains/rao.sign#dem.is.zero" role="enum">No Demand (Master Plan)</GUIRef>
				</ListItem>
			</List>
		</Note>
		<GeneralSection><SectionTitle>When signals are generated</SectionTitle>
			<List><ListIntro>Item signals as well as resource signals are generated when you:</ListIntro>
				<ListItem>Run a signal update using the <GUIRef href="/baanerp/cp/rao/cprao1210m000" role="session">Update Signals (cprao1210m000)</GUIRef> session.</ListItem>
				<ListItem>Initialize or maintain a scenario by running the <GUIRef href="/baanerp/cp/rpd/cprpd4200m000" role="session">Initialize, Roll, and Update Scenario (cprpd4200m000)</GUIRef> session.</ListItem>
				<ListItem>Run a master-plan simulation.</ListItem>
				<ListItem>Run an order simulation.</ListItem>
			</List>
			<List><ListIntro>Only resource signals are generated when you:</ListIntro>
				<ListItem>Rebuild the resource planning by running the <GUIRef href="/baanerp/cp/rmp/cprmp3200m000" role="session">Rebuild Resource Planning (cprmp3200m000)</GUIRef> session.</ListItem>
				<ListItem>Update the resource planning in the <GUIRef href="" role="manual">Resource Master Plan (cprmp3501m000)</GUIRef> session.</ListItem>
				<ListItem>Update the resource signals in the <GUIRef href="/baanerp/cp/rao/cprao1130m000" role="session">Resource - Signals (cprao1130m000)</GUIRef> session.</ListItem>
			</List>
			<Paragraph>When you update your item signals in the <GUIRef href="/baanerp/cp/rao/cprao1125m000" role="session">Planner/Item Signals (cprao1125m000)</GUIRef> session, only item signals are generated. Some types of item signals are also generated when you run the <GUIRef href="/baanerp/cp/rmp/cprmp2240m000" role="session">Convert Master Plan to Planned Orders (cprmp2240m000)</GUIRef> session.</Paragraph>
		</GeneralSection>
		<GeneralSection><SectionTitle>Master planning and order planning</SectionTitle>
			<Paragraph>To a certain degree, <Link href="/baanerp/cp/glossary/glossary#000059" role="glossary">master planning</Link> and <Link href="/baanerp/cp/glossary/glossary#000060" role="glossary">order planning</Link> differ when it comes to the signals generated. Some item signals are typically generated when SSA ERP creates or updates an item master plan, whereas other item signals are usually created in the context of order planning.</Paragraph>
			<Paragraph>For example, order signals are mostly generated in order planning, while demand signals are usually generated in master planning. Inventory signals, on the other hand, are created in both types of planning.</Paragraph>
		</GeneralSection>
		<Note><SectionTitle>Note</SectionTitle>
			<Paragraph>When SSA ERP generates or updates planned orders, the item master plan for the item involved (if there is any) is checked as well. Running the <GUIRef href="/baanerp/cp/rrp/cprrp1210m000" role="session">Generate Order Planning (cprrp1210m000)</GUIRef> session, for example, not only yields item signals typically belonging to order planning, but can also produce item signals which are usually confined to master planning (such as demand signals).</Paragraph>
