			<Paragraph>Backflushing is carried out for each <Link href="/baanerp/ti/glossary/glossary#000305" role="glossary">clustered line-station order (CLSO)</Link> (see the <Link href="/baanerp/ti/asc/tiasc7530m000" role="session">Clustered Line Station Orders (tiasc7530m000)</Link> session). The number of CLSOs produced each day, depends on the mode you select with the <GUIRef href="/baanerp/ti/asc/tiasc0100m000#tiasc000.trpr" role="field">Transaction Processing</GUIRef> parameter, which you define in the <GUIRef href="/baanerp/ti/asc/tiasc0100m000" role="session">Assembly Control Parameters (tiasc0100m000)</GUIRef> session. For <GUIRef href="/baanerp/ti/domains/asc.trpr#order" role="enum">Order Based</GUIRef> processing, each individual assembly order provides a CLSO for each line station, creating many CLSOs each day. For <GUIRef href="/baanerp/ti/domains/asc.trpr#line" role="enum">Line Station Based</GUIRef> processing, there is only one CLSO each day, for each line station. All the hours and materials for all buckets, all line-station variants, and all line-station orders are clustered into one CLSO for each line station. This mode is for high-volume production environments.</Paragraph>
