Create a calculated dimension by measure

Sat, 28 May 2016 08:41:36 GMT

Hi,

I have a requirement where i have three columns

Customer Order_No Amount

A Order1 100

A Order2 400

B Order3 500

C Order4 400

C Order5 200

Now I want to make a dimension where I would have three values , Average Order value (Amount/count(Order_No)) <200,

Average Order value (Amount/count(Order_No)) >200<500 and Average Order value (Amount/count(Order_No)) >500.

So there shall be a new dimension which has there three values and I can use it as a proper dimension in tree chart ?

I guess your internal grouping entity should be Customer?

In the script:

INPUT:

LOAD * INLINE [

Customer, Order_No, Amount

A, Order1, 100

A, Order2, 400

B , Order3 , 500

C , Order4 , 400

C, Order5, 200

];

LOAD Customer, AvgOrderAmount,

If(AvgOrderAmount <200, Dual('<200',200),

If(AvgOrderAmount <500, Dual('>=200 <500',500),Dual('>=500',520))) as Group;

LOAD Customer, Sum(Amount) / Count(Order_No) as AvgOrderAmount

RESIDENT INPUT

Group By Customer;

You can also use

= If(Sum(Amount) / Count(Order_No) <200, Dual('<200',200),

If(Sum(Amount) / Count(Order_No) <500, Dual('>=200 <500',500),Dual('>=500',520)))

as calculated dimension without the additional data model change

Hi ,

Thanks for the reply , I think I couldn't tell you the exact problem, there is a field Gross Amount , and NO_() which is the order number and i need to create a dimension which has 5 values , <1500, 1500< and 3500> , 3500< and less than 7500, 7500< and <15000 and 15000<. I have tried your above formula but it is giving me an invalid dimension , Can you please help in this , this is on urgent basis requirement

for two chunks I have tried below one

If(Sum(Gross_Amount) / Count(No_) <1500, Dual('<1500',1500),

If(Sum(Gross_Amount) / Count(No_) <3500, Dual('>=1500 <3500',3500),Dual('>=3500',3520)))

Stefan correct me if you think I am wrong, but won't we need Aggr() function here for the calculated dimension?

=Aggr(If(Sum(Amount)/Count(Order_No) < 200, Dual('<200', 200),

If(Sum(Amount)/Count(Order_No) < 500, Dual('>=200 <500', 500), Dual('>=500', 520))), Customer)

You're right of course, Sunny, we need the advanced aggregation when we want to calculate the avg order amount per Customer and then create the buckets based on these values (just like in the load script).

Try this using the aggr function:

Aggr(If(Sum(Gross_Amount) / Count(No_) <1500, Dual('<1500',1500),

If(Sum(Gross_Amount) / Count(No_) <3500, Dual('>=1500 <3500',3500),Dual('>=3500',3520))), NO_)

It would be easier to answer if you could post some sample records and your expected result.

If your data looks like

Gross Amount, NO_()

100, 1

1600,2

3000,3

1000,4

i.e. you don't need to aggregate per NO_(), then you don't need the aggr() function:

create a calculated dimension like

=If( [Gross Amount] < 1500, Dual('<1500',1500),

If( [Gross Amount] < 3500, Dual('>=1500 <3500',3500),

If( [Gross Amount] < 7500, Dual('>=3500 <7500',7500),

If( [Gross Amount] < 15000, Dual('>=7500 <15000',15000),Dual('>=15000 ',20000)))))

As expression, use

=Count(DISTINCT [NO_()])

If you need to aggregate the amounts per NO_(), add the aggr() around the if()

=Aggr(

If( Sum([Gross Amount])/Count([NO_()] < 1500, Dual('<1500',1500),

If( Sum([Gross Amount])/Count([NO_()] < 3500, Dual('>=1500 <3500',3500),

If(Sum([Gross Amount])/Count([NO_()] < 7500, Dual('>=3500 <7500',7500),

If( Sum([Gross Amount])/Count([NO_()]< 15000, Dual('>=7500 <15000',15000),Dual('>=15000 ',20000)))))

,[NO_()] )

edit: added the aggregations to the second sample.
