Hello All,

I have following situation  with a HANA Calculation View output

 

 

COLUMN1   COLUMN2   COLUMN3     
TECH111      A11111      MATERAL1 
TECH111      A11112      MATERAL2
TECH111      A11112      MATERAL3
TECH111      A11113      MATERAL4
TECH112      A11113      MATERAL5
TECH112      A11114      MATERAL6
TECH112      A11115      MATERAL7
TECH112      A11116      MATERAL8

 

 

 

I want to get the count for each unique value papering in Column 2

 

i.e.A11111 appears 1 time, A11112 and A11113 appears 2 time and so on..

 

And In column 5 I would like to get a Total for All the instances (Sum of Column 4)

 

So the final output i need is shown below..

 

 

COLUMN1    COLUMN2  COLUMN3   ........COLUMN4    ........COLUMN5
TECH111      A11111      MATERAL1        1                    12
TECH111      A11112      MATERAL2        2                    12
TECH111      A11112      MATERAL3        2                    12  
TECH111      A11113      MATERAL4        2                    12
TECH112      A11113      MATERAL5        2                    12
TECH112      A11114      MATERAL6        1                    12
TECH112      A11115      MATERAL7        1                    12
TECH112      A11116      MATERAL8        1                    12

 

 

I want to achieve this inside a graphical Calculation view. I tried to create a Calculated Column for the counter but it did not work. There are very limited functions available to use inside a Calculated Column. Do I have to get this done in SQL Script Calculation view? My preference is getting it done in Graphical Calculation view.

 

Under Distinct values tab of data preview I can see the exact output I want to see but is there any way to have that as a result of my Calc View?

There is something called as counters in the output of a calc view. It appears to be built for this purpose but it always gives a value of 1.

 

I would appreciate any inputs. Ideas. Thanks.

 

Regards

Abhijit
