		<Paragraph>Use a baseline for... A baseline is a snapshot of the scheduled time line of activities. It can be used to time-phase a top down budget version in the <GUIRef href="/baanerp/tp/ptc/tpptc5200m000" role="session">Generate Time Phased Budget (tpptc5200m000)</GUIRef> session. The time-phased budget is calculated by using the budget version and the baseline (taking into account the earned value method, and the scheduled dates of the activities).</Paragraph>
		<Paragraph>A baseline is used for performance measurement. If you want to generate performance measurement, the baseline must be Approved and also the budget version must be Actual. Amounts of the scheduled activities that can be released depends on where the activity on the baseline is positioned in the performance measured periods.</Paragraph>
		<Paragraph>For example, activity A has a distributed amount of a 10,000 guilders with the Start and End Date Percent earned value method. 10% is released when starting the activity, 90% is released at finishing it. The baseline is approved and falls into three periods. In the first period A starts, therefore an amount of 1000 guilders is released for that period. In the second period work is still performed on A and so none is released, and in the third period when A is finished, an amount of 9000 guilders is released. To release the budget amount SSA ERP looks at the baseline data and the EVM.</Paragraph>

		<List><ListIntro>Create a baseline The baseline data depends on the start and end dates of the activity structure or milestones used in a project. In <GUIRef href="/baanerp/tp/pss" role="module">Project Scheduling System</GUIRef> there are two sessions where you can indirectly create or update a baseline:</ListIntro>
			<ListItem>The <GUIRef href="/baanerp/tp/pss/tppss2121m000" role="session">Milestone Baseline (tppss2121m000)</GUIRef> session.</ListItem>
			<ListItem>The <GUIRef href="/baanerp/tp/pss/tppss2120m000" role="session">Activity Baseline (tppss2120m000)</GUIRef> session. From one of these session you can enter <GUIRef href="/baanerp/tp/pss/tppss2220m000" role="session">Create/Update Baseline (tppss2220m000)</GUIRef> session where you can create or update a baseline that is based on the underlying activity structure of this specific project.</ListItem>
		</List>
		<Paragraph>The <GUIRef href="/baanerp/tp/pss/tppss0520m000" role="session">Baselines (tppss0520m000)</GUIRef> session provides an overview and enables you to change the baseline status.</Paragraph>
