      <Paragraph>Maintenance concepts are <Link href="/baanerp/ts/glossary/glossary#000075" role="glossary">item</Link>-specific reference
		activities, or predicted activities that are linked to an item. To do this,
		specify for each item which <Link href="/baanerp/ts/glossary/glossary#RefereActivi_ts" role="glossary">reference activities</Link> are
		required, and the number of times these activities must be carried out. You can
		specify the <Link href="/baanerp/ts/glossary/glossary#Requirements_ts" role="glossary">requirements</Link> for each
		reference activity.</Paragraph>
      <List>
         <ListIntro>You can define maintenance concepts in the following
		  sessions:</ListIntro>
         <ListItem> 
            <GUIRef href="/baanerp/ts/spc/tsspc1120m000" role="session">Maintenance Concepts - Item (tsspc1120m000)</GUIRef>
         </ListItem>
         <ListItem> 
            <GUIRef href="/baanerp/ts/spc/tsspc1125m000" role="session">Maintenance Concept - Predicted Activities (tsspc1125m000)</GUIRef>
         </ListItem>
      </List>
      <Paragraph>If you define a <Link href="/baanerp/ts/glossary/glossary#MainteConcep_ts" role="glossary">maintenance concept</Link>, you can
		make use of the functionality offered by the multilevel serialized item
		structure. If, for example, a maintenance activity is required for several
		products of one product family, the product family can be included in the
		serialized item structure. The family is included as a serialized item under
		which the common maintenance activities are defined.</Paragraph>
      <Paragraph>The <Link href="/baanerp/ts/glossary/glossary#UsageClass_ts" role="glossary">usage class</Link> enables you to
		define more than one maintenance concept for an item.</Paragraph>

         <SectionTitle>How to define a maintenance concept</SectionTitle>
         <Steps>
            <Step>
               <StepTitle>Reference Activities</StepTitle>
               <Paragraph>You must define the reference activity, which is the basic
				element of a maintenance concept, in the <GUIRef href="" role="manual">Reference Activities (tsacm1101m000)</GUIRef> session. You can use these reference activities to
				create a maintenance concept, a maintenance prediction, or a maintenance
				planning.</Paragraph>
               <Paragraph>The reference activity always contains a service type.
				This service type has an important role when a maintenance plan must be
				defined. For more details about service types, refer to the Master Data
				Management (MDM) module procedure.</Paragraph>
            </Step>
            <Step>
               <StepTitle>Inspection Templates</StepTitle>
               <Paragraph>If a measurement type is linked to a reference activity,
				the measurement type is called a measurement inspection. This measurement
				inspection must be performed as a part of the reference activity. When the
				measurement is carried out and norm values are exceeded, one or more activities
				must be performed. Therefore, the follow-up activity must be available to be
				inserted in the <GUIRef href="" role="manual">Reference Activities - Measurement Types (tsacm3160m000)</GUIRef> session. A measurement is the value of a specific
				variable (measuring quantity) of an object in a specific situation.</Paragraph>
            </Step>
            <Step>
               <StepTitle>Maintenance Concepts - Item</StepTitle>
               <Paragraph>Maintenance concept is a list of activities to be carried
				out on a anonymous item as a part of maintenance policy. The frequency at
				which, the activity has to be carried out is also specified. You can specify
				various maintenance concepts for the same anonymous item. To enable this, you
				can use the entity usage class.</Paragraph>
               <Paragraph>Use the <GUIRef href="" role="manual">Maintenance Concepts - Item (tsspc1120m000)</GUIRef> session to list the reference activities that
				constitute an item's maintenance concept. On the <GUIRef href="" role="manual">Specific</GUIRef> menu, click <GUIRef href="" role="manual">Generate Predictions</GUIRef> to start the <GUIRef href="" role="manual">Generate Prediction (tsspc1225m000)</GUIRef> session, which you can use
				to generate a list of predicted activities for the item, based on the item's
				reference activities listed in this session. You can click <GUIRef href="" role="manual">Resource Requirements</GUIRef> to start the <GUIRef href="" role="manual">Reference Activity - Resource Requirements (tsacm2120m000)</GUIRef> session, which you can use to view the
				list of resource requirement for the particular reference activity.</Paragraph>
