Getting the Counters right with stacked Calculation Views

Data Modeling in SAP HANA provides great amount of flexibility to the end user. One of the key capabilities in Modeling sector of SAP HANA is computation of user required calculations. One of the variations in calculation which end user can perform in Calculation Views/Analytic Views is 'Counter'.

Let us now understand the operations under the hood when stack of Calculation Views are created in a project.

Consider a simple 'Product Details' table which comprise of the product information along with its sales information as shown below:


Product Store Customer Quantity Revenue Unit
Headset METRO ALDI 2 120 PACKG
ipad METRO ALDI 10 6000 PACKG
ipad METRO IBM 10 6000 PACKG
Budweiser EDEKA IBM 360 720 BOTTL

Exception aggregation modeling with Graphical Calc view

The business scenario is quite common in the BI reporting. Consider a KPI, required to be calculated at a low level of granularity, but the reporting is required at the higher level of granularity. With the default aggregation behavior of the calc view, the constituents of the Calculated KPI might also be aggregated at the reporting granularity level, resulting in incorrect value for the Calculated KPI.

To elaborate more on this, consider the following data model for the Sales Transaction. The transaction data is captured for Product Sold on a given date in a store. The table structure can be defined as follows:

( STORE_ID    nvarchar(10),  --- Store Id
  PROD_ID    nvarchar(10),  --- Product Id
  PROD_CAT    nvarchar(10),  --- Product Category
  PROD_PRICE  decimal(10,2), --- Product Price
  SOLD_QTY    integer,      --- Product Quantity Sold in a Sales transaction
  TRANS_DATE  nvarchar(8),  --- Sales Transaction Date
  STORE_REG  nvarchar(10)  --- Region in which the Store is located
);

The business rule could be:
The product price may vary each day, hence the Net Sales need to be calculated for the Product Price on the transaction date and Quantity Sold on the day.
