					<Paragraph>If you did not specify a carrier in the <GUIRef href="/baanerp/cp/rpd/cprpd7130m000" role="session">Supplying Relationships (cprpd7130m000)</GUIRef> session, SSA ERP calculates the order start date with the supply lead time that you defined in that same session.</Paragraph>
					<Paragraph>SSA ERP plans the supply lead time using the calendar linked to the supply resource specified in the <GUIRef href="/baanerp/cp/rpd/cprpd7130m000" role="session">Supplying Relationships (cprpd7130m000)</GUIRef> session. If you did not specify a supply resource, <GUIRef href="/baanerp/tc" role="package">Common Data</GUIRef> uses the calendar of the item's enterprise unit.</Paragraph>
