	<GeneralSection><Paragraph>SSA ERP uses <Link href="/baanerp/tc/glossary/glossary#000370" role="glossary">calendar recurrences</Link> to model daily, weekly, monthly, or yearly recurring (non)available days in a <Link href="/baanerp/tc/glossary/glossary#Calendar.tc" role="glossary">calendar</Link>.</Paragraph>
		<Paragraph>Instead of defining a special <Link href="/baanerp/tc/glossary/glossary#ResoActiType.tc" role="glossary">availability type</Link> for (non)availability, or clearing the <GUIRef href="/baanerp/tc/ccp/tcccp0120m000#tcccp020.avlb" role="formfield">Available</GUIRef> check box for each date within a recurring range individually in the <GUIRef href="/baanerp/tc/ccp/tcccp0120m000" role="session">Calendar Working Hours (tcccp0120m000)</GUIRef> session, you can use calendar recurrences.</Paragraph>
		<Paragraph>The advantage of calendar recurrences is that you can define recurring exceptions in a calendar, and set a time schedule for daily, weekly, monthly, or yearly (non)available time in one action.</Paragraph>
		<ProcedureList><ListIntro>To define a calendar recurrence, take the following steps:</ListIntro>
			<ListItem>Define a <Link href="/baanerp/tc/glossary/glossary#000370" role="glossary">calendar recurrence</Link>. For each recurrence you must define the details in the <GUIRef href="/baanerp/tc/ccp/tcccp0141m000" role="session">Calendar Recurrences (tcccp0141m000)</GUIRef> session. When you define a calendar recurrence, you must fill the following fields: <List><ListItem><GUIRef href="/baanerp/tc/ccp/tcccp0141m000#tcccp041.kpat" role="formfield">Type</GUIRef>: the schedule according to which the (non)availability occurs, which can be <GUIRef href="/baanerp/tc/domains/ccp.kpat#dly" role="enum">Daily</GUIRef>, <GUIRef href="/baanerp/tc/domains/ccp.kpat#wkly" role="enum">Weekly</GUIRef>, <GUIRef href="/baanerp/tc/domains/ccp.kpat#mntly" role="enum">Monthly</GUIRef>, or <GUIRef href="/baanerp/tc/domains/ccp.kpat#yrly" role="enum">Yearly</GUIRef>.</ListItem>
					<ListItem><GUIRef href="/baanerp/tc/ccp/tcccp0141m000#tcccp041.stdt" role="formfield">Start Date</GUIRef> and <GUIRef href="/baanerp/tc/ccp/tcccp0141m000#tcccp041.endt" role="formfield">End Date</GUIRef>: the period for which the calendar recurrence is valid.</ListItem>
					<ListItem><GUIRef href="/baanerp/tc/ccp/tcccp0141m000#tcccp041.intl" role="formfield">Recurrence</GUIRef>: a value that determines the frequency at which (non)availability occurs.</ListItem>
				</List>
			</ListItem>
			<ListItem>Define the details for the calendar recurrence in the <GUIRef href="/baanerp/tc/ccp/tcccp0142m000" role="session">Calendar Recurrence Working Hours (tcccp0142m000)</GUIRef> session. You must define: <List><ListItem>The <Link href="/baanerp/tc/glossary/glossary#ResoActiType.tc" role="glossary">availability type</Link> to which the calendar recurrence applies.</ListItem>
					<ListItem>Whether the resource that uses the corresponding calendar is available or not. You can do so by selecting or clearing the <GUIRef href="/baanerp/tc/ccp/tcccp0142m000#tcccp042.avlb" role="formfield">Working Hours</GUIRef> check box.</ListItem>
					<ListItem>The working hours: the exact time of (non)availability. To define the working hours, you can select one of the <Link href="/baanerp/tc/glossary/glossary#TimeIntervTy.tc" role="glossary">working hours types</Link> that you defined in the <GUIRef href="/baanerp/tc/ccp/tcccp0103m000" role="session">Working Hours Types (tcccp0103m000)</GUIRef> session, or use the <GUIRef href="/baanerp/tc/ccp/tcccp0142m000#tcccp042.sttm" role="formfield">Start Time</GUIRef> field and the <GUIRef href="/baanerp/tc/ccp/tcccp0142m000#tcccp042.entm" role="formfield">End Time</GUIRef> field.</ListItem>
					<ListItem>The <Link href="/baanerp/tc/glossary/glossary#000368" role="glossary">efficiency factor</Link>.</ListItem>
					<ListItem>The <Link href="/baanerp/tc/glossary/glossary#CapaciPercen.tc" role="glossary">capacity percentage</Link>.</ListItem>
				</List>
			</ListItem>
		</ProcedureList>
		<Paragraph>If you click the <GUIRef href="/baanerp/tc/ccp/tcccp0120m000#actualize.calendar" role="formcommand">Update Calendar</GUIRef> button in the <GUIRef href="/baanerp/tc/ccp/tcccp0120m000" role="session">Calendar Working Hours (tcccp0120m000)</GUIRef> session, SSA ERP starts the <GUIRef href="/baanerp/tc/ccp/tcccp0226m000" role="session">Update Calendar (tcccp0226m000)</GUIRef> session. During the update of the working hours and the capacity data of the calendar with this session, SSA ERP takes into account the calendar recurrence details that you defined in the previously described process.</Paragraph>

			<Paragraph>If you defined the calendar recurrence for nonavailability, the entire day of the calendar is nonavailable, for the corresponding availability type.</Paragraph>
