	<GeneralSection><Paragraph>Interchangeability means that the demand for a specific material's and/or end item's effectivity unit can be fullfilled by inventory of another effectivity unit of the same item.</Paragraph>
		<List><ListIntro>Interchangeability can be used in the following processes:</ListIntro>
			<ListItem>During order planning in <GUIRef href="/baanerp/cp" role="package">Enterprise Planning</GUIRef>.</ListItem>
			<ListItem>In an outbound advice in <GUIRef href="/baanerp/wh" role="package">Warehouse Management</GUIRef>. If effectivity units are interchangeable, one unit can use another unit’s inventory to meet a requirement.</ListItem>
		</List>
		<List><ListIntro>The basic question is: can an effectivity unit A be replaced by an effectivity unit B for an item XYZ? To answer this, interchangeability of effectivity units (indicated by the setting of Interchangeable check boxes) is checked on three levels:</ListIntro>
			<ListItem>Company level</ListItem>
			<ListItem>Item level</ListItem>
			<ListItem>Item – effectivity series level</ListItem>
		</List>
		<Paragraph>How to set interchangeability in SSA ERP on different levels is described below.</Paragraph>
		<GeneralSection><SectionTitle>Company level</SectionTitle>
			<Paragraph>Interchangeability on the company level is leading. If the <GUIRef href="/baanerp/tc/uef/tcuef0100s000#tcuef000.ichg" role="formfield">All Effectivity Units are Interchangeable</GUIRef> check box in de <GUIRef href="/baanerp/tc/uef/tcuef0500m000" role="session">Unit Effectivity Parameters (tcuef0500m000)</GUIRef> session is selected, all effectivity units are interchangeable for all orders.</Paragraph>
			<ExampleSection><SectionTitle>Example</SectionTitle>
				<Paragraph>The order-planning engine in <GUIRef href="/baanerp/cp" role="package">Enterprise Planning</GUIRef> has a demand for item Q-DEVICE with effectivity unit 75. No inventory exists for this item/unit. However, inventory is available for item Q-DEVICE with effectivity unit 79. If the <GUIRef href="/baanerp/tc/uef/tcuef0100s000#tcuef000.ichg" role="formfield">All Effectivity Units are Interchangeable</GUIRef> check box is selected, interchangeability is defined on the company level so the inventory for Q-DEVICE/79 can be used to replace the demand for Q-DEVICE/75.</Paragraph>
			</ExampleSection>
			<Paragraph>If the <GUIRef href="/baanerp/tc/uef/tcuef0100s000#tcuef000.ichg" role="formfield">All Effectivity Units are Interchangeable</GUIRef> check box is selected, the pegging function of the <GUIRef href="/baanerp/tc/uef" role="module">Unit Effectivity</GUIRef> module is not fully exploited but unit effectivity is used for configuration issues and non-material matters, for example, to test alternative routings and sourcing strategies, or to examine learning curves.</Paragraph>

		<GeneralSection><SectionTitle>Item level</SectionTitle>
			<Paragraph>If the <GUIRef href="/baanerp/tc/uef/tcuef0100s000#tcuef000.ichg" role="formfield">All Effectivity Units are Interchangeable</GUIRef> check box in the <GUIRef href="/baanerp/tc/uef/tcuef0500m000" role="session">Unit Effectivity Parameters (tcuef0500m000)</GUIRef> session is cleared, you can set interchangeability at the item level in the <GUIRef href="/baanerp/tc/ibd/tcibd0501m000" role="session">Items - General (tcibd0501m000)</GUIRef> details session. If you select the <GUIRef href="/baanerp/tc/ibd/tcibd0101s000#tcibd001.ichg" role="formfield" Update="No">Effectivity Units are Interchangeable</GUIRef> check box in the <GUIRef href="/baanerp/tc/ibd/tcibd0501m000" role="session">Items - General (tcibd0501m000)</GUIRef> details session, all effectivity units for a specific item are interchangeable.</Paragraph>
			<ExampleSection><SectionTitle>Example</SectionTitle>
				<Paragraph>The order-planning engine in <GUIRef href="/baanerp/cp" role="package">Enterprise Planning</GUIRef> has a demand for item Q-DEVICE with effectivity unit 75. No inventory exists for this item/unit. However, inventory is available for item Q-DEVICE with effectivity unit 55. The effectivity units are not interchangeable at the company level. However, the <GUIRef href="/baanerp/tc/ibd/tcibd0101s000#tcibd001.ichg" role="formfield" Update="No">Effectivity Units are Interchangeable</GUIRef> check box in the <GUIRef href="/baanerp/tc/ibd/tcibd0501m000" role="session">Items - General (tcibd0501m000)</GUIRef> details session is selected, so the item Q-DEVICE is defined as interchangeable. <GUIRef href="/baanerp/wh" role="package">Warehouse Management</GUIRef> can therefore issue material of Q-DEVICE/55 to the shop floor.</Paragraph>
			</ExampleSection>
			<Paragraph>Selecting the <GUIRef href="/baanerp/tc/ibd/tcibd0101s000#tcibd001.ichg" role="formfield" Update="No">Effectivity Units are Interchangeable</GUIRef> check box in the <GUIRef href="/baanerp/tc/ibd/tcibd0501m000" role="session">Items - General (tcibd0501m000)</GUIRef> details session is mainly useful to be able to interchange effectivity units of common material in the lower levels of the BOM.</Paragraph>
		</GeneralSection>
		<GeneralSection><SectionTitle>Item – effectivity series level</SectionTitle>
			<List><ListIntro>You can define interchangeability on the item – effectivity series level in three ways in the <GUIRef href="/baanerp/tc/uef/tcuef0101m000" role="session">Items - Effectivity Series (tcuef0101m000)</GUIRef> session:</ListIntro>
				<ListItem>If you select the <GUIRef href="/baanerp/tc/uef/tcuef0101m000#tcuef001.ichg" role="formfield">Interchangeable in Series</GUIRef> check box, a material demand for an item/effectivity unit can be replaced by other inventory of effectivity units of the same series.</ListItem>
				<ListItem>If you select the <GUIRef href="/baanerp/tc/uef/tcuef0101m000#tcuef001.iwos" role="formfield">Interchangeable with other Interchangeable Series</GUIRef> check box, a material demand for an item/effectivity unit can be replaced by inventory for effectivity units of other series, if the <GUIRef href="/baanerp/tc/uef/tcuef0101m000#tcuef001.iwos" role="formfield">Interchangeable with other Interchangeable Series</GUIRef> check box for those series is also selected.</ListItem>
				<ListItem>If you select the <GUIRef href="/baanerp/tc/uef/tcuef0101m000#tcuef001.iwsc" role="formfield">Interchangeable with Stnd. Conf. and vice versa</GUIRef> check box, a material demand for an item/effectivity unit can be replaced by inventory for effectivity unit 0 (standard inventory). Also demand for effectivity unit 0 can be replaced by effectivity units of this series.</ListItem>
			</List>
			<ExampleSection><SectionTitle>Example</SectionTitle>
				<Paragraph>The order-planning engine in <GUIRef href="/baanerp/cp" role="package">Enterprise Planning</GUIRef> has created a production order which requires material CRT-DEVICE with effectivity unit 75. No inventory exists for effectivity unit 75 but a large inventory is available for effectivity unit 80. Can CRT-DEVICE/80 replace the requirement for CRT-DEVICE/75? Note that CRT-DEVICE is not interchangeable on the company level or the item level.</Paragraph>
				<Paragraph>Effectivity unit 75 is defined for series NM of end item RADAR, with sequence numbers 1-100. This series is interchangeable with other series. Effectivity unit 80 is defined for series AD of end item RADAR, with sequence numbers 1-50. This series is defined as not interchangeable with other series.</Paragraph>
				<Paragraph>As only one of the item – effectivity series is interchangeable with other series, the effectivity units 75 and 80 are not interchangeable for item CRT-DEVICE.</Paragraph>
