         <List>
            <ListIntro>To update the demand and inventory data displayed in the
          item master plan (but not generate a supply plan), you have the following
          options:</ListIntro>
            <ListItem>Choose the Update
          command in the <GUIRef href="/baanerp/cp/rmp/cprmp2101m000" role="session">Item Master Plan (cprmp2101m000)</GUIRef> session.</ListItem>
            <ListItem>Run the <GUIRef href="/baanerp/cp/rpd/cprpd4200m000" role="session">Initialize, Roll, and Update Scenario (cprpd4200m000)</GUIRef> session.</ListItem>
         </List>
         <Paragraph>If you use the Update
        command in the <GUIRef href="/baanerp/cp/rmp/cprmp2101m000" role="session">Item Master Plan (cprmp2101m000)</GUIRef> session, the master plan data of the
        current item is updated, including the <Link href="/baanerp/cp/glossary/glossary#000044" role="glossary">goods-flow</Link> data from the <Link href="/baanerp/cp/glossary/glossary#000027" role="glossary">execution level</Link>.</Paragraph>
         <Paragraph>If you want to update
        the item master plan data for a range of plan items, and/or need more options,
        you can use the <GUIRef href="/baanerp/cp/rpd/cprpd4200m000" role="session">Initialize, Roll, and Update Scenario (cprpd4200m000)</GUIRef> session. Here you can enable or disable the update of
        the goods-flow data, as well as the generation of requirements (for an existing
        production plan). You can also use this session to update goods-flow data for
        product families (by aggregation from the item master plans of the child
        items).</Paragraph>
         <Paragraph>If you do not only
        want to update the demand and inventory data, but to (re)generate a supply plan
        as well, you need to run a master plan simulation.</Paragraph>

A number of options are
          available for the simulation run. For example, you can:</ListIntro>

          plan periods for which the simulation is performed.</ListItem>

          master plan simulation. This session can handle a range of plan items, and has
          a number of extra options. For example, you can:</ListIntro>
