		<Paragraph>Usually, you will only do a <Emphasis>full update</Emphasis> of the vendor rating, if you changed the parameters in the <GUIRef href="/baanerp/td/pur/tdpur0100m800" role="session">Vendor Rating Parameters (tdpur0100m800)</GUIRef> session and/or no longer want the manual changes to be taken into account.</Paragraph>
		<List><ListIntro>You can update the vendor ratings in the following ways:</ListIntro>
			<ListItem>By selecting the <GUIRef href="/baanerp/td/pur/tdpur8850m000#full.update" role="formfield">Full Update</GUIRef> check box in the <GUIRef href="/baanerp/td/pur/tdpur8850m000" role="session">Update Vendor Rating (tdpur8850m000)</GUIRef> session.</ListItem>

		</List>
		<Note><SectionTitle>Note</SectionTitle>
			<Paragraph>If you did not change parameters and also did not change the vendor ratings manually, the calculation of the vendor rating has the same result for both a selected check box and a cleared check box.</Paragraph>
		</Note>
		<GeneralSection><SectionTitle>The <GUIRef role="formfield" href="/baanerp/td/pur/tdpur8850m000#full.update">Full Update</GUIRef> check box is cleared</SectionTitle>
			<Paragraph>If the <GUIRef href="/baanerp/td/pur/tdpur8850m000#full.update" role="formfield">Full Update</GUIRef> check box is cleared, only the net changes are taken into account. So, only the purchase order lines that are newly processed in the <GUIRef href="/baanerp/td/pur/tdpur4223m000" role="session">Process Purchase Orders (tdpur4223m000)</GUIRef> session and fall within the defined period, are taken into account. The calculation is as follows:</Paragraph>
			<Formula><Paragraph UserLevel="Novice" UserType="Taskuser">
 NR = ((OR * V) + (nRL * nVL)) / (V + nVL)
</Paragraph>
				<FigLegend><LegendEntry><Symbol>NR</Symbol>
