Network Bandwidth Test for HANA Server and Replication Calculation

For network bandwidth testing you need the newest NIPING version for this test, please follow SAP note 799428 to get it.

First start the NIPING server on Secondary server site which you plan to use as data replication target site with the following command:

niping -s -I 0 (the last character is zero, not the letter O)

One can also use the command: niping -s

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.
