         <Paragraph>To a certain degree, <Link href="/baanerp/cp/glossary/glossary#000059" role="glossary">master planning</Link> and <Link href="/baanerp/cp/glossary/glossary#000060" role="glossary">order planning</Link> differ when
		  it comes to the <Link href="/baanerp/cp/glossary/glossary#000371" role="glossary">exception messages</Link> generated. Some item <Link href="/baanerp/cp/glossary/glossary#000371" role="glossary">exception messages</Link> are typically generated when ERP Enterprise creates or updates an
		  item master plan, whereas other item <Link href="/baanerp/cp/glossary/glossary#000371" role="glossary">exception messages</Link> are usually created in the context of order planning.</Paragraph>
         <Paragraph>For example, order <Link href="/baanerp/cp/glossary/glossary#000371" role="glossary">exception messages</Link> are mostly generated in order planning, while demand <Link href="/baanerp/cp/glossary/glossary#000371" role="glossary">exception messages</Link> are usually generated in master planning. Inventory <Link href="/baanerp/cp/glossary/glossary#000371" role="glossary">exception messages</Link>, on the other hand, are created in both types of planning.</Paragraph>
      </GeneralSection>
      <Note>
         <SectionTitle>Note</SectionTitle>
         <Paragraph>When ERP Enterprise generates or updates
		  planned orders, the item master plan for the item involved (if there is any) is
		  checked as well. Running the <GUIRef href="/baanerp/cp/rrp/cprrp1210m000" role="session">Generate Order Planning (cprrp1210m000)</GUIRef> session, for example, not only yields item <Link href="/baanerp/cp/glossary/glossary#000371" role="glossary">exception messages</Link> typically belonging to order planning, but can also produce
		  item <Link href="/baanerp/cp/glossary/glossary#000371" role="glossary">exception messages</Link> which are usually confined to master
		  planning (such as demand <Link href="/baanerp/cp/glossary/glossary#000371" role="glossary">exception messages</Link>).</Paragraph>
