aggregation in set analysis

prrajendran — Sat, 16 Nov 2024 19:50:01 GMT

Hi Experts,

i have a table with Date, 15 Min Interval time, product no, ID & Name in my qvw.

Sample Input in the excel sheet attached

i have to provide a grouped result for a day at 15 min intervals like below. i have to find how many singles, doubles & triples in a day

But i have to exclude 'N/A' in the 'Product Details' field for my grouped result.

Each Product No will have multiple Product details associated with it. for example, in the above table, for 09/10/2019 at 12:00:00, there are 3 products with the same product no. so my result for 12:00:00 should be

09/10/2019 12:00:00 1 (Triple)

similarly, at 00:30:00, 3 products with product no SA711, but 2 of them shows N/A in product details. so i have to exclude that 2. my result at 00:30:00 should be

09/10/2019 00:30:00 1(Single)

so My entire output for the above table should be like:

Output:

Date	15 Min Intervals	Single	Double	Triple
09/10/2019	00:00:00	1	1	0
09/10/2019	00:15:00	1	1	0
09/10/2019	00:30:00	1	0	0
09/10/2019	01:15:00	0	1	0
09/10/2019	01:30:00	1	1	0
09/10/2019	01:45:00	0	1	1
09/10/2019	06:00:00	0	1	1
09/10/2019	06:15:00	0	1	1
09/10/2019	12:00:00	0	0	1

I have attached the input and output data in excel.

Can you please help me with the expression to get this result?

There you go:

Create your logic at script level:

Aggregate your table by [Product No], then create link key using [Date] and [15 Min Intervals].

Use the new count column from the aggregated table above at front end with set analysis to filter count by 1,2,3.

Thanks and regards,

Hi Arthur,

Thank you for your response.

but i have to bring the solution through expression.

i cannot do the changes in script as my fields are segregated in different tables.

can you please help me with an expression to get the result

Try the below expressions:

Single:

Count(if([Product Details]<>'N/A' and Aggr(count(if([Product Details]<>'N/A',[Product No])),Date,[15 Min Intervals],[Product No])=1,[Product No]))

Double:

Count(if([Product Details]<>'N/A' and Aggr(count(if([Product Details]<>'N/A',[Product No])),Date,[15 Min Intervals],[Product No])=2,[Product No]))

Triple:

Count(if([Product Details]<>'N/A' and Aggr(count(if([Product Details]<>'N/A',[Product No])),Date,[15 Min Intervals],[Product No])=3,[Product No]))
