         <ListIntro>An extension consists mainly of invoicing agreements. The
		  relation to the budget is defined in the initial budget and/or the budget
		  adjustment detail lines. To control extensions, four status values are
		  available:</ListIntro>
         <ListItemHead>
            <GUIRef href="/baanerp/tp/domains/ptc.stls#free" role="option">Free</GUIRef>
         </ListItemHead>
         <ListItem>Use the extension for budgeting but not for registering actual
		  costs.</ListItem>
         <ListItemHead>
            <GUIRef href="/baanerp/tp/domains/ptc.stls#actual" role="option">Actual</GUIRef>
         </ListItemHead>
         <ListItem>You can post actual costs to the extension, but it is not
		  possible to invoice the extension.</ListItem>
         <ListItemHead>
            <GUIRef href="/baanerp/tp/domains/ptc.stls#definite" role="option">Final</GUIRef>
         </ListItemHead>

         </ListItemHead>
         <ListItem>You can post costs to the extension and you can invoice the
		  extension.</ListItem>
      </List>
      <Paragraph>Extensions can be
		invoiced according to a fixed price, the budgeted contract amount or the
		billing amounts from the actual transactions. If it is necessary to control
		orders separately, you can define a start and finish date for the extension.
		You register the progress of an extension by extension or by extension within <Link href="/baanerp/tp/glossary/glossary#ControCode_tp" role="glossary">control code</Link>. Projects can
		be controlled by specific extensions or with the control budget.</Paragraph>
      <List>
         <ListIntro>You can use the sessions relating to <Link href="/baanerp/tp/glossary/glossary#000017" role="glossary">extensions</Link> to enter, display
		  and print out changes to a project that affect customer invoicing. Four
		  extension types are supported:</ListIntro>

         <ListIntro>The following types of fluctuation settlement exist:</ListIntro>
         <ListItemHead>Index fluctuation settlement</ListItemHead>
         <ListItem>You can settle a
		  percentage of the contract price according to price indices. The billable
		  amount is based on invoiced installments or on the progress.</ListItem>
         <ListItemHead>Price fluctuation settlement</ListItemHead>
         <ListItem>You can settle items in
		  the budget that contain a specific material (for example, copper) while
		  accounting for possible price fluctuations of that material. Price indices are
		  maintained at the material and data level. The invoicing is based on the
		  progress registered in Project Progress. Invoices concerning the billing of
		  price variations are generated. These invoices are processed by <GUIRef href="/baanerp/ci/sli" role="module">Sales Invoicing</GUIRef>, based on
		  the invoicing method defined in the <GUIRef href="/baanerp/tp/pdm" role="module">Project Definition</GUIRef> module. Budget entries that contain specific materials can be settled while
		  taking account of possible price fluctuations for those materials. Price
		  indices are maintained by material and date. Billing is based on progress.</ListItem>

         <Paragraph>You cannot define extensions of type Fluctuation Settlement
