Hi Indu,
You can use the "Counter" in Calc view. As per the modeling guide for HANA:
Counters add a new measure to the calculation view definition to count the recurrence of an attribute. For example, to count how many times product appears.
Create counters to obtain the number of distinct values of an attribute (optional)
a) Select the default aggregation node.
b) In the Output pane, right-click Calculated Columns.
c) From the context menu, choose New Counter. Enter a name and description (label).
d) To hide the counter during data preview, select the Hidden checkbox.
e) To add attributes in the Counters panel, choose Add and choose OK.
Remember
You can only create counters on the default aggregation node.
Please refer to the documentation for further details.
This can be used in your case to calculate the average (sum(KF) / count(KF))
Regards,
Ravi
