ACCUMULATIVE BY GROUP AND DATE

[Andres_Fuentes1]

Hello everyone, I hope you are very well, I have a problem that has not worked for me at all, I need to accumulate a numeric column by group and date. The example table is the following:

GROUP	DATE	TOTAL	CUMULATIVE_BY_GROUP
A	01-01-2022	12	12
A	02-01-2022	15	27
A	03-01-2022	3	30
A	04-01-2022	3	33
A	05-01-2022	16	49
A	06-01-2022	7	56
B	01-01-2022	3	3
B	02-01-2022	6	9
B	03-01-2022	18	27
B	04-01-2022	6	33
B	05-01-2022	2	35
B	06-01-2022	12	47
C	01-01-2022	16	16
C	02-01-2022	4	20
C	03-01-2022	19	39
C	04-01-2022	16	55
C	05-01-2022	4	59
C	06-01-2022	6	65

Thanks.
