         <ListItem>Click the New Group

         <ListItem>Click the Add a New

         <ListItem>Determine the planning

      <Paragraph>You can use the <GUIRef href="/baanerp/cp/rpd/cprpd3110m000#cprpd310.agty" role="manual">Aggregation Type</GUIRef> field in the <GUIRef href="/baanerp/cp/rpd/cprpd3110m000" role="session">Aggregation Relationships (cprpd3110m000)</GUIRef> details session to determine whether <GUIRef href="/baanerp/cp" role="package">Enterprise Planning</GUIRef> must

      <Paragraph>You can also use the <GUIRef href="" role="manual">Generate Aggregation Relationships (cprpd3211m000)</GUIRef> session to let ERP Enterprise generate aggregation
