cumulative YTD

[deblina_rai]

Can anyone please help me to find YTD amount like below ?

TRANSACTION_AMOUNT should be the sum of TRANSACTION_AMOUNT on that process date

YTD should be the sum of TRANSACTION_AMOUNTs up to that date.

Something like this.

Date	Acc	Rep	Other Dims	Trxn Amt	YTD
1/5/2019	AccA	RepX	XXXX	25	25
2/10/2019	AccA	RepX	XXXX	75	100
7/15/2019	AccA	RepX	XXXX	80	180
2/10/2019	AccB	RepY	YYYY	20	20
7/18/2019	AccB	RepY	YYYY	40	60

I need YTD as sum  of amount  till that Process date  in cumulative  YTD
