	<GeneralSection><Paragraph>The third step that SSA ERP carries out in the calculate objective criteria ratings process, is the creation of rating records for each purchase order line in the <GUIRef href="/baanerp/td/pur/tdpur8106m000" role="session">Objective Ratings (tdpur8106m000)</GUIRef> session.</Paragraph>
		<Paragraph>In the <GUIRef href="/baanerp/td/pur/tdpur8106m000" role="session">Objective Ratings (tdpur8106m000)</GUIRef> session, the ratings for all objective criteria are displayed. Also, the overall rating for the concerned purchase order line is displayed.</Paragraph>
		<GeneralSection><SectionTitle>Calculation of overall rating purchase order line</SectionTitle>
			<Paragraph>The overall rating for the purchase order line is calculated as follows:</Paragraph>
			<Formula><Paragraph UserLevel="Novice" UserType="Taskuser">
Overall rating purchase order line = sum (objective rating * weighting) </Paragraph>
			</Formula>
			<Paragraph>SSA ERP retrieves the weightings of the objective criteria from the <GUIRef href="/baanerp/td/pur/tdpur0100m800" role="session">Vendor Rating Parameters (tdpur0100m800)</GUIRef> session. The weightings are recalculated to true percentages, which are taken into account.</Paragraph>

			<List><ListIntro>Every time you add a new line, SSA ERP automatically updates the objective criteria ratings per business partner/criterion combination in the following sessions:</ListIntro>

			</List>
		</GeneralSection>
		<Paragraph>The new rating is the running average, which is calculated as follows:</Paragraph>
		<Formula><Paragraph UserLevel="Novice" UserType="Taskuser">New rating = ((old rating * old value) + (this 
rating * this value)) / (old value + this value)
</Paragraph>

			<Paragraph>The value can be of three different types, according to the setting of the <GUIRef href="/baanerp/td/pur/tdpur0100m800#tdpur000.wmth.8" role="formfield">Weighting Method</GUIRef> field in the <GUIRef href="/baanerp/td/pur/tdpur0100m800" role="session">Vendor Rating Parameters (tdpur0100m800)</GUIRef> session:</Paragraph>

		<GeneralSection><SectionTitle>Update of total values</SectionTitle>
			<List><ListIntro>The total values (also called: running totals) of the three above mentioned value types, are also automatically updated when you add an order line. The total values are updated by business partner in the following sessions:</ListIntro>
				<ListItem><GUIRef href="/baanerp/td/pur/tdpur8102m000" role="session">Vendor Ratings by Period (tdpur8102m000)</GUIRef>
				</ListItem>
				<ListItem><GUIRef href="/baanerp/td/pur/tdpur8102m100" role="session">Vendor Ratings by Criterion (tdpur8102m100)</GUIRef>
				</ListItem>
			</List>
			<Paragraph>The total values of all three value types are always updated, regardless of the used weighting methods. So, if you have a hundred business partners in a specific period, then three hundred running totals must be updated.</Paragraph>

		<Note><SectionTitle>Note</SectionTitle>
			<Paragraph>Subjective criteria are not taken into account in the calculation of the objective-criteria ratings and the overall rating per purchase order line. So, the overall vendor rating per business partner per period can only be calculated after the subjective-criteria ratings are also calculated.</Paragraph>
