Running Total

Tue, 30 Dec 2014 13:45:11 GMT

I have a data set similar to the below table. For every 'Date' and 'Key' I have a 'Residual' value. This residual value will be the same for each key. However, I am having some issues with calculating the 'ResidualTotal' field. This field should be a running total of the residual values for each key. I know how to incorporate the rangesum/above function (i.e. rangesum(above(sum(residual),0,rowno()))) but I do not know how to implement it in this scenario when I do not want it by row number and I cannot replace rowno() with 'Date' and 'Key'.

Date	Key	Residual	ResidualTotal
1/1/2014	A	20	20
1/2/2014	A	20	20
1/3/2014	A	20	20
1/4/2014	A	20	20
1/5/2014	B	90	110
1/6/2014	B	90	110
1/7/2014	B	90	110

Any help would be greatly appreciated.

hi there, hope this helps you , find attachment

RESIDUAL:

LOAD * INLINE [

Date, Key, Residual

1/1/2014, A, 20

1/2/2014, A, 20

1/3/2014, A, 20

1/4/2014, A, 20

1/5/2014, B, 90

1/6/2014, B, 90

];

RESIDENT_TOTAL_STAGE1:

Load distinct Key,rangesum(Residual,0)

Residual

Resident RESIDUAL;

RESIDENT_TOTAL_STAGE2:

Load Key,

if(RowNo()=1,Residual,

Residual+rangesum(Peek('ResidualTotal'),0) )

ResidualTotal

Resident RESIDENT_TOTAL_STAGE1

;

DROP Table RESIDENT_TOTAL_STAGE1;

Thank you, Prem. This method definitely works but would you know how to put this in an expression instead of the script? I eventually want to chart this and the running total will be dynamic depending on which keys the user selects.

Thanks

Dim: Date, Key

Expr:If(Aggr(RowNo(),Key)=1,Residual,If(Not IsNull(Aggr(RowNo(),Key)),Residual + Above(TOTAL Residual),Above(TOTAL Column(1))))

Try this expr

If(Aggr(RowNo(),Key),Residual+ Alt(Above(TOTAL Residual),0),Above(TOTAL Column(1)))

How about:

rangesum(above(TOTAL aggr(max(Residual),Key),0,9999))
