      <Paragraph>You can enter an
		effective date and an expiry date for the item sourcing types <GUIRef href="/baanerp/tc/domains/kitm#purchase" role="option">Purchased</GUIRef> and <GUIRef href="/baanerp/tc/domains/kitm#manufacture" role="option">Manufactured</GUIRef>. As a result,
		these attributes apply during the specified period of time.</Paragraph>
      <Paragraph>The item type that you
		specify in the <GUIRef href="/baanerp/tc/ibd/tcibd0101s000" role="session">Item - General (tcibd0101s000)</GUIRef> session and the <GUIRef href="/baanerp/tc/ibd/tcibd0102s000" role="session">Item - General Defaults (tcibd0102s000)</GUIRef> session is the default item type. This is
		overruled by the item type selected for specific periods of time in the <GUIRef href="/baanerp/tc/ibd/tcibd0110s000" role="session">Date-Effective Item Data (tcibd0110s000)</GUIRef> session. The data in the <GUIRef href="/baanerp/tc/ibd/tcibd0110s000" role="session">Date-Effective Item Data (tcibd0110s000)</GUIRef> session is company-specific. Specifying the item
		type in the <GUIRef href="/baanerp/tc/ibd/tcibd0110s000" role="session">Date-Effective Item Data (tcibd0110s000)</GUIRef> session allows you to share data between
		logistic companies and control the item type per logistic company.</Paragraph>

         <ListIntro>ERP Enterprise checks what the item type is at the current date and

         <Paragraph>If you use <GUIRef href="/baanerp/dm" role="package">Data Management</GUIRef>, you can use the <GUIRef href="/baanerp/dm/chm" role="module">Change Management</GUIRef> module for the change control of the item type. ERP Enterprise enters the item type and
		  its effective date and expiry data when you approve a change order in the <GUIRef href="/baanerp/dm/chm" role="module">Change Management</GUIRef> module. In this way, you can change the item type and other ERP Enterprise data at the
		  same time. You must select the <GUIRef href="/baanerp/tc/ibd/tcibd0101s000#tcibd001.chma" role="manual">CHM Control</GUIRef> check box in the <GUIRef href="/baanerp/tc/ibd/tcibd0101s000" role="session">Item - General (tcibd0101s000)</GUIRef> session to indicate that you want to use change order
		  control for the item.</Paragraph>
