	<GeneralSection><Paragraph>Error signals are item signals that indicate errors occurring during a planning run.</Paragraph>
		<Paragraph>Some errors are relatively easy to solve, for example, by supplying a default value or parameter where SSA ERP expects one. In other cases, however, the error can be of a more serious nature, and can lead to failure of the planning as a whole.</Paragraph>
		<GeneralSection><SectionTitle>Fatal Error</SectionTitle>
			<List><ListIntro>A fatal error occurred. A message is given to specify the fatal error. Examples of a fatal error:</ListIntro>
				<ListItem>The program is running out of memory.</ListItem>
				<ListItem>An internal sort failed.</ListItem>
			</List>
			<Paragraph>In most cases the session that started the signal generation will be aborted. If any planning has been generated, it can probably not be trusted.</Paragraph>
			<Paragraph>This signal is not related to a specific item.</Paragraph>

			<Paragraph>While trying to generate orders for <Link href="/baanerp/ti/glossary/glossary#RepetiItem.ti" role="glossary">repetitive items</Link>, no default order quantity could be found.</Paragraph>
			<List><ListIntro>The default order quantity for repetitive items is calculated in <GUIRef href="/baanerp/ti" role="package">Manufacturing</GUIRef>, on the basis of:</ListIntro>
				<ListItem>The <Link href="/baanerp/ti/glossary/glossary#BasicCapaci.ti" role="glossary">basic capacity</Link> of the <Link href="/baanerp/ti/glossary/glossary#BottleWorkce.ti" role="glossary">bottleneck workcenter</Link> for the repetitive item in question, as specified in the <GUIRef href="/baanerp/ti/rou/tirou1101m000" role="session">Item - Routings (tirou1101m000)</GUIRef> session.</ListItem>
				<ListItem>The basic capacity by resource unit for this bottleneck work center, as specified in the <GUIRef href="/baanerp/ti/rou/tirou0101m000" role="session">Work Centers (tirou0101m000)</GUIRef> session.</ListItem>

		<GeneralSection><SectionTitle>No Supplying Relationship</SectionTitle>
			<Paragraph>While trying to generate a planned distribution order, SSA ERP could not find any <Link href="/baanerp/cp/glossary/glossary#000005" role="glossary">supplying relationships</Link> for the item involved. As a result, no planned distribution order is generated.</Paragraph>
			<Paragraph>You can define supplying relationships for a plan item in the <GUIRef href="/baanerp/cp/rpd/cprpd7130m000" role="session">Supplying Relationships (cprpd7130m000)</GUIRef> session.</Paragraph>
		</GeneralSection>
		<GeneralSection><SectionTitle>No Supplying Business Partner</SectionTitle>
			<Paragraph>While trying to generate a planned purchase order, SSA ERP could not find any suppliers for the item involved. However, the planned purchase order is still generated.</Paragraph>
			<Paragraph>You can define suppliers for a plan item in the <GUIRef href="/baanerp/td/ipu/tdipu0101m000" role="session">Item - Purchase (tdipu0101m000)</GUIRef> session.</Paragraph>
		</GeneralSection>
		<GeneralSection><SectionTitle>Item Error</SectionTitle>
			<Paragraph>An item-specific error occurred. The nature of the error is specified in the signal. In most cases the error is such that the planning for the specified item has failed and cannot be trusted.</Paragraph>
		</GeneralSection>
		<GeneralSection><SectionTitle>No Items for Plan Unit</SectionTitle>
			<Paragraph>A particular plan unit is empty, that is, no plan items have been assigned to it.</Paragraph>
			<Paragraph>You can assign a plan item to a plan unit in the <GUIRef href="/baanerp/cp/rpd/cprpd1100m000" role="session">Items - Planning (cprpd1100m000)</GUIRef> session, by entering the plan unit in the <GUIRef href="/baanerp/cp/rpd/cprpd1100m000#cprpd100.mrpu" role="formfield">Master Plan Unit</GUIRef> field.</Paragraph>
			<Paragraph>This type of signal is not related to a specific item.</Paragraph>
		</GeneralSection>
		<GeneralSection><SectionTitle>No WLC Parameters Defined</SectionTitle>
			<Paragraph>A particular item is assigned to a plan unit for which the <Link href="/baanerp/cp/glossary/glossary#000061" role="glossary">master-planning engine</Link> is <GUIRef href="/baanerp/cp/domains/rpd.plme#workloadcontrol" role="enum">Workload Control</GUIRef> (see the <GUIRef href="/baanerp/cp/rpd/cprpd6100m000" role="session">Plan Unit (cprpd6100m000)</GUIRef> session), but the plan unit's WLC parameters have not been defined.</Paragraph>
			<Paragraph>You can define the WLC parameters in the <GUIRef href="/baanerp/cp/wlc/cpwlc2101m000" role="session">Work Load Control Parameters (cpwlc2101m000)</GUIRef> session.</Paragraph>
		</GeneralSection>
		<GeneralSection><SectionTitle>Insufficient Capacity</SectionTitle>
			<Paragraph>The production plan is decreased due to insufficient free capacity on one of the resources defined in the <Link href="/baanerp/ti/glossary/glossary#BillOfCritic.ti" role="glossary">bill of critical capacities</Link>. This type of signal is generated in the <Link href="/baanerp/cp/glossary/glossary#000013" role="glossary">workload control (WLC)</Link> planning engine.</Paragraph>
		</GeneralSection>
		<GeneralSection><SectionTitle>Insufficient Materials</SectionTitle>
			<Paragraph>The production plan is decreased due to a lack of one of the components specified in the <Link href="/baanerp/ti/glossary/glossary#000081" role="glossary">bill of critical materials</Link> for a certain plan item. This type of signal is generated in the <Link href="/baanerp/cp/glossary/glossary#000013" role="glossary">workload control (WLC)</Link> planning engine.</Paragraph>
		</GeneralSection>
		<GeneralSection><SectionTitle>Planning Failed</SectionTitle>
			<Paragraph>Planning has failed because the required quantity could not be planned. The nature of the error is specified in the signal.</Paragraph>
