get Aggr Sum per each row

[maxsheva]

Hi,

data:

LOAD * Inline [

Group, Subgroup, Date, Value, Value2

Group1, Subgroup1, 01/01/2017, 100, 2

Group1, Subgroup1, 01/02/2017, 0, 3

Group1, Subgroup1, 01/03/2017, 200, 2

Group1, Subgroup1, 01/04/2017, 0, 1

Group2, Subgroup1, 01/05/2017, 100, 4

Group2, Subgroup1, 01/06/2017, 0, 2

Group2, Subgroup1, 01/07/2017, 0, 1

]

I need to get the result as in table2. But I would like to show some logic in table1.

Any suggestion is welcome.

table1

Group	Subgroup	Date	Value	RepeatValue	Value2	Multiply( Sum(Value2)*RepeatValue )
Group1	Subgroup1	01/01/2017	100	100	2	200
Group1	Subgroup1	01/02/2017	0	100	3	300
Group1	Subgroup1	01/0/3/2017	200	200	2	400
Group1	Subgroup1	01/04/2017	0	200	1	200
Group2	Subgroup1	01/05/2017	100	100	4	400
Group2	Subgroup1	01/06/2017	0	100	2	200
Group2	Subgroup1	01/07/2017	0	100	1	100

table2

Group	Sum(Multiply)
Group1	1100
Group2	700

Create the RepeatValue field in the script:

SET DateFormat = 'MM/DD/YYYY';

INPUT:

LOAD * Inline [

Group, Subgroup, Date, Value, Value2

Group1, Subgroup1, 01/01/2017, 100, 2

Group1, Subgroup1, 01/02/2017, 0, 3

Group1, Subgroup1, 01/03/2017, 200, 2

Group1, Subgroup1, 01/04/2017, 0, 1

Group2, Subgroup1, 01/05/2017, 100, 4

Group2, Subgroup1, 01/06/2017, 0, 2

Group2, Subgroup1, 01/07/2017, 0, 1

];

RESULT:

LOAD *,

If(Value = 0 and Peek(Group)=Group and Peek(Subgroup)=Subgroup, Peek(RepeatValue),Value) as RepeatValue

Resident INPUT

ORDER BY Group, Subgroup, Date asc;

DROP TABLE INPUT;

Then use the field in your chart expression

Group	Sum(RepeatValue*Value2)
	1800
Group1	1100
Group2	700

Stefan, thanks for solution.

Would you please advise how to make the same in case where two different tables?

Script below doesn't provide an expected result.

INPUT1:
LOAD * Inline [
Group, Subgroup, Date, Value
Group1, Subgroup1, 01/01/2017, 2
Group1, Subgroup1, 01/02/2017, 3
Group1, Subgroup1, 01/03/2017, 2
Group1, Subgroup1, 01/04/2017, 1
Group2, Subgroup1, 01/05/2017, 4
Group2, Subgroup1, 01/06/2017, 2
Group2, Subgroup1, 01/07/2017, 1
];

Left Join(INPUT1)
INPUT2:
LOAD * Inline [
Group, Subgroup, Date, Value2
Group1, Subgroup1, 01/01/2017, 100

Group1, Subgroup1, 01/03/2017, 200
Group2, Subgroup1, 01/05/2017, 100
];

RESULT:
LOAD *,
If(Value2 = 0 and Peek(Group)=Group and Peek(Subgroup)=Subgroup, Peek(RepeatValue2),Value2) as RepeatValue2
Resident INPUT1
ORDER BY Group, Subgroup, Date asc;

DROP TABLE INPUT1;

When checking if the value of Value2 is a valid one, you need to consider that due to the JOIN, you need to check for NULL, not zero.

RESULT:

LOAD *,

If(Len(trim(Value2))=0 and Peek(Group)=Group and Peek(Subgroup)=Subgroup, Peek(RepeatValue2),Value2) as RepeatValue2

Resident INPUT1

ORDER BY Group, Subgroup, Date asc;

It works. Thank you very much!
