	<GeneralSection><Paragraph>When <GUIRef href="/baanerp/cp" role="package">Enterprise Planning</GUIRef> carries out purchase-order planning, the volume that is planned for a supplier depends on the value of the <GUIRef href="/baanerp/cp/rpd/cprpd7120m000#cprpd720.diru" role="formfield">Allocation Rule</GUIRef> field in the <GUIRef href="/baanerp/cp/rpd/cprpd7120m000" role="session">Supply Strategy (cprpd7120m000)</GUIRef> session.</Paragraph>
		<Paragraph>The resulting volume is checked against the lot sizing rules. The ordered quantity can be divided over multiple purchase orders as a result of the lot sizing. See <Link href="/baanerp/cp/onlinemanual/000060" role="manual">Lot sizing</Link>.</Paragraph>

			<Formula><Paragraph UserLevel="Novice" UserType="Taskuser"> OQ = RQ x PE / 100</Paragraph>
			</Formula>
			<Paragraph>Where:</Paragraph>
			<TABLE border="1"><TBODY><TR><TD>OQ</TD>
						<TD>ordered quantity</TD>
					</TR>
					<TR><TD>REQ</TD>
						<TD>quantity that remains to be planned</TD>

						<TD>originally required quantity</TD>
					</TR>
					<TR><TD>PE</TD>
						<TD>percentage</TD>
					</TR>
				</TBODY>
			</TABLE>
			<Paragraph>If the ordered quantity (OQ) is greater than the quantity that remains to be planned (REQ), OQ is set to REQ.</Paragraph>
			<Paragraph>The percentage is defined in the <GUIRef href="/baanerp/td/ipu/tdipu0110m000#tdipu010.srcp" role="formfield">Sourcing Percentage</GUIRef> field in the <GUIRef href="/baanerp/td/ipu/tdipu0110m000" role="session">Item - Purchase Business Partner (tdipu0110m000)</GUIRef> session.</Paragraph>
