      <Paragraph>If you only want to check ATP for a plan item without performing
		component CTP, capacity CTP, and channel ATP, the calculation is based on the
		order plan of the item.</Paragraph>
      <Paragraph>The detailed transactions of the plan item are used to see
		exactly when ATP is created. Therefore, this calculation is not a bucket-based
		calculation, but a time-phased calculation.</Paragraph>
      <Paragraph>Whether the plan item has a master plan or not is irrelevant. In
		both situations, the previous detailed time-phased calculation is used, in the
		order horizon as well as in the planning horizon. Therefore, in this case, no
		difference exists between order-based and master-based checks.</Paragraph>
