      <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">Warehousing</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 LN on different levels is
		described below.</Paragraph>

         <SectionTitle>Company level</SectionTitle>
         <Paragraph>Interchangeability on the company level is leading. If the <GUIRef href="/baanerp/tc/uef/tcuef0100s000#tcuef000.ichg" role="manual">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

            <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="manual">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>

            <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

However, the <GUIRef href="/baanerp/tc/ibd/tcibd0101s000#tcibd001.ichg" role="manual" 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">Warehousing</GUIRef> can therefore issue material of Q-DEVICE/55 to

            <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>
