	</Header>
	<HelpTopic><AimSection><Paragraph>Use this session to detect errors (loops) in <Link href="/baanerp/ti/glossary/glossary#MultilBillOf.ti" role="glossary">multilevel production bills of material</Link>. A loop appears when the same item is used at several levels in a <Link href="/baanerp/ti/glossary/glossary#BillOfMateri.ti" role="glossary">bill of material (BOM)</Link>, while the item is one time a parent item, and another time a child.</Paragraph>
		</AimSection>
		<GeneralSection><Paragraph>When you calculate cost prices and material requirements, SSA ERP checks multilevel bills of material for loops. You are therefore advised to run this session regularly, as it allows you to correct incorrect data at an early stage.</Paragraph>
