	<GeneralSection><Paragraph>The backflushing of materials takes place when you report a quantity completed (see <Link href="/baanerp/ti/onlinemanual/000202" role="manual">Backflushing procedure</Link> ). SSA ERP calculates and processes the quantities that must be backflushed.</Paragraph>
		<List><ListIntro>From which inventory the materials are backflushed depends on the value of the the following fields:</ListIntro>
			<ListItem>The <GUIRef href="/baanerp/ti/bom/tibom1110m000#tibom010.lsel" role="formfield">Lot Selection</GUIRef> field. In this field in the <GUIRef href="/baanerp/ti/cst/ticst0101m000" role="session">Estimated Materials (ticst0101m000)</GUIRef> session or in the <GUIRef href="/baanerp/ti/bom/tibom1110m000" role="session">Bill of Material (tibom1110m000)</GUIRef> session you must indicate whether all materials must be issued from the same lot, from a specific lot, or from an arbitrary (any) lot. This applies especially for lot-controlled items (defined in the <GUIRef href="/baanerp/tc/ibd/tcibd0501m000" role="session">Items - General (tcibd0501m000)</GUIRef> session). If the material is not a lot-controlled item, the value is always Any.</ListItem>
			<ListItem>The <GUIRef href="/baanerp/wh/wmd/whwmd4500m000#whwmd400.obpr" role="formfield">Outbound Method</GUIRef> field. The value of the <GUIRef href="/baanerp/wh/wmd/whwmd4500m000#whwmd400.obpr" role="formfield">Outbound Method</GUIRef> field in the <GUIRef href="/baanerp/wh/wmd/whwmd4500m000" role="session">Items - Warehousing (whwmd4500m000)</GUIRef> session determines from which inventory the materials are backflushed. <List><ListIntro>You can select one of the following values:</ListIntro>
					<ListItem><GUIRef href="/baanerp/tc/domains/obpr#lifo" role="enum">LIFO</GUIRef>: the inventory with the latest inventory date is backflushed first.</ListItem>
					<ListItem><GUIRef href="/baanerp/tc/domains/obpr#fifo" role="enum">FIFO</GUIRef>: the inventory with the earliest inventory date is backflushed first.</ListItem>

	<GeneralSection><SectionTitle>Serialized items</SectionTitle>
		<Paragraph>Serialized items can only be backflushed if in the <GUIRef href="/baanerp/wh/wmd/whwmd4500m000" role="session">Items - Warehousing (whwmd4500m000)</GUIRef> details session the <GUIRef href="/baanerp/wh/wmd/whwmd4100s000#whwmd400.sinv" role="formfield">Serials in Inventory</GUIRef> check box is cleared, and the <GUIRef href="/baanerp/wh/wmd/whwmd4100s000#whwmd400.sisf" role="formfield">Register Serial Issue During As Built</GUIRef> field is <GUIRef href="/baanerp/tc/domains/yesno#yes" role="enum">Yes</GUIRef>. In all other cases, serialized items cannot be backflushed.</Paragraph>
		<Paragraph>If the serialized item is lot-controlled, the lot from which the items are backflushed is based on the outbound method ( <GUIRef href="/baanerp/wh/domains/ina.valm#lifo" role="enum">Last In First Out (LIFO)</GUIRef>, <GUIRef href="/baanerp/wh/domains/ina.valm#fifo" role="enum">First In First Out (FIFO)</GUIRef> ) as is defined in the <GUIRef href="/baanerp/wh/wmd/whwmd4500m000" role="session">Items - Warehousing (whwmd4500m000)</GUIRef> details session.</Paragraph>

	<GeneralSection><SectionTitle>Pick materials from the warehouse</SectionTitle>
		<Paragraph>The materials are backflushed after the production order is completed. However, the materials are already collected from the warehouse when working on the order, with the help of a material list. The person which collects the materials from the warehouse must pick the materials from the same lots as the lots that will be determined later by SSA ERP on the hand of the <GUIRef href="/baanerp/ti/bom/tibom1110m000#tibom010.lsel" role="formfield">Lot Selection</GUIRef> field and the <GUIRef href="/baanerp/wh/wmd/whwmd4500m000#whwmd400.obpr" role="formfield">Outbound Method</GUIRef> field during the backflushing procedure. That person therefore has to apply the same rules as SSA ERP when collecting the materials. Consequently, the picking instructions are based on the following factors:</Paragraph>

			<ListItem><Emphasis>Same</Emphasis>: All materials must be picked from the same lot. If a lot does not contain enough material, another lot must be taken that contains enough material to cover the demand.</ListItem>
			<ListItem><Emphasis>Specific</Emphasis>: The materials must be picked from the lot that is specified in the <GUIRef href="/baanerp/ti/cst/ticst0101m000#ticst001.clot" role="formfield">Lot Code</GUIRef> field.</ListItem>

		<List><ListTitle>The best fit package structure</ListTitle>
			<ListItem>Materials can be packaged in different ways. The best fit package structure indicates which package units you can pick best to collect your materials in a economical way. SSA ERP also picks inventory according to these rules.</ListItem>
