Accumulation in Load

[#1]

Hi

To avoid having to use above() excessively in my formulas I tried to accumulate my numbers in the load command. As the previous() however is always looking into the source table the following code does not work

Normal:
LOAD * INLINE [
dim, mycount
1, 3
1, 1
1, 4
2, 7
2, 18
2, 1
];

Accumulated:
LOAD dim
, if(previous(dim)=dim,previous(mycume)+mycount,mycount) as mycume
RESIDENT Normal;

and the following is only the sum of the current and above row

Accumulated:
LOAD dim
, if(previous(dim)=dim,previous(mycount)+mycount,mycount) as mycume
RESIDENT Normal;

HI,

I`m not sure i have understood your question.

can elaborate a bit. since i have tried to reproduce your scenario. it worked as i expected.

Below is my code

Accu:

LOAD

* INLINE

[

;

Noconcatenate

Accu_Temp:

Load

* Resident Accu order by dim

Asc;

Drop

Table

Accu;

Load

dim, if(peek(dim) = dim, peek(mycount_new)+mycount,mycount) as mycount_new,mycount

Resident

Accu_Temp;

Drop

Table

Accu_Temp;
