I have to make a straight table with 1 column showing Cumulative Difference.

[#1]

In my table, I have week, month, No of QOE Subscribers.

I have to create a new column, and place cumulative difference of the QoE Subscribers in that column. Also, the first row should be null (0) and the cumulative difference should start from the 2nd column.

Ex -

Week	Month	Qoe Subscribers	Cumulative Difference
Week1	Jan	23	0
Week1	Feb	25	2
Week1	Mar	22	-3
Week1	Apr	30	8

Any help is appreciated. Thanks.

May be this:

If(RowNo(TOTAL) = 1, 0, RangeSum([Qoe Subscriber], -Above(TOTAL [Qoe Subscriber])))

This may be help you,

If(RowNo(TOTAL) = 1, 0, RangeSum([Qoe Subscribers] - Above(TOTAL [Qoe Subscribers])))
