/* Reusable view is created for Schedule Line Calculation fields.
   This view fetches the data from the Analytical table MMPUR_ANA_EKET which has been craeted to increase the performance of the Schedule line
   data retrieval.

   Data is stored in the analytical table as a result of the Migration Job which is trigered from EKET to MMPUR_ANA_EKEET at the start of
   each delivery/release cycle .  After succesful migration run; a configuration table MMPUR_ANA_CONF (Interface view: I_PurgAnalyticsConfiguration)
   is filled with system client and field IsIntrastatReportingRelevant as 'X' . During consumption of R views; this configuration table should be
   used to determine whether the data is sucessfully migrated to new Analytical table or not .

   ScheduleLineDeliveryDate: Next Delivery date for the open Schedule Lines
   ScheduleLineOpenQuantity: Next Delivery Quantity for the open Schedule Lines with latest delivery date
   Flag PurgDocSchdLnHasNextDelivery gives the latest Schedule Line where GR is open .

   Consumption logic: Schedule Line fields from the R views in the Analytical stack (R_POItemEnhcdNextDeliveryCalc) and old stack(R_POItemNextDeliveryCalc)
   should be consumed using a case statement as the CASE approach is faster w.r.t execution time rather than UNION ALL approach  */
