New products not present in previous month

Hi All,

I need to make a table in script in which i want the following fields:

MonthYear, Count(New Products)

These new products are the ones which arent present in last month

Eg

MonthYear     Product

Aug'17               A

Aug'17               B

Aug'17               C

Sep'17               A

Sep17                D


The count for sep'17 should be 1.

it is not necessary that all products from Aug'17 will flow in Sep'17


Hence we need to compare each product in curr month from prev month.


Can you please suggest how.

I need to implement this in the script

Hi,

Following code will work:

T:

LOAD * where not Exists (Product);

LOAD * Inline

[

MonthYear,Product

Aug17,A

Aug17,B

Aug17,C

Sep17,A

Sep17,D

];

NoConcatenate

T2:

LOAD MonthYear,count(Product) as Product

Resident T

Group by MonthYear;

DROP Table T;

if you just add new row to the inline load Dec17, B, the script will not work any more

hi Chhavi,

do you always need to compare only current and previous month?

it doesn't matter how many years of data you have, the result always should be one row - current Month and count. Is it correct?

or you want to compare month in each row with prev. month?

MonthYear,Product

Aug17,A

Aug17,B

Aug17,C

Sep17,A

Sep17,D

Dec17,B

the result should be

Aug17, 3

Sep17, 1

Dec17, 2

Hi,

For this logic use below code:

T:

LOAD *

where not Exists (productflag);

LOAD *,if(RecNo()=1,MonthYear&Product,if(MonthYear = Peek(MonthYear),MonthYear&Product,peek(MonthYear)&Product)) as productflag,RecNo() Inline

[

MonthYear,Product

Aug17,A

Aug17,B

Aug17,C

Sep17,A

Sep17,D

Dec17,B

];

NoConcatenate

T2:

LOAD MonthYear as M,count(Product) as P

Resident T

Group by MonthYear;

If that is the case then my first code will work for the same.

If your case is resolved then close this thread and mark the correct answer correct.

load MonthYear,

len(PurgeChar(List,Previous(List))) as Count;

load MonthYear,Concat(Product) as List

Resident T

Group by MonthYear;

drop Table T;

just one note: you MonthYear should be sorted correctly
