	<GeneralSection><Paragraph>The calculation of the overall vendor rating per <Link href="/baanerp/tc/glossary/glossary#BusinePartne.tc" role="glossary">business partner</Link> is the fourth stage in the vendor rating calculation procedure.</Paragraph>
		<Paragraph>The overall vendor rating is calculated by the <GUIRef href="/baanerp/td/pur/tdpur8850m000" role="session">Update Vendor Rating (tdpur8850m000)</GUIRef> session and displayed in the <GUIRef href="/baanerp/td/pur/tdpur8102m000" role="session">Vendor Ratings by Period (tdpur8102m000)</GUIRef> session and the <GUIRef href="/baanerp/td/pur/tdpur8102m100" role="session">Vendor Ratings by Criterion (tdpur8102m100)</GUIRef> session.</Paragraph>
		<Paragraph>Before SSA ERP calculates the overall vendor rating, the period rating for the newest business partner/period combination is calculated. SSA ERP calculates the period rating for the business partner/period combination as follows:</Paragraph>

Period rating = sum (all criteria ratings * actual weightings)
