Hi @Xabinav,

In load editor you can use RangeSum() and Peek(). 

TABLE:
LOAD ROW_NUM,ORDER_DATE, ORDER_AMOUNT, RangeSum(peek('Cumulative') , ORDER_AMOUNT) AS Cumulative INLINE [
ROW_NUM,	ORDER_DATE,	ORDER_AMOUNT,	
1,	23/02/2017,	260,
2,	23/02/2017,	100,
3,	25/06/2017,	50,
4,	17/08/2017,	495,
5,	17/08/2017,	100,
6,	24/10/2017,	0,
7,	24/10/2017,	175,
8,	17/01/2018,	0,
9,	18/01/2018,	395,
10,	24/01/2018,	100,
11,	13/02/2018,	100,
12,	12/03/2018,	100,
13,	18/04/2018,	175,
14,	10/05/2018,	100,
15,	10/05/2018,	780,
16,	10/05/2018,	100,
17,	29/05/2018,	150
];
