For example CY2015 should be 723+1466+908=3097, CY2016 should be 723+1466+908 +1404=4501, etc.
Thanks!
Hi Liezele,
do you need to display that on the report, are you ok to have this info in the form of a chart so that you can use a cumulative chart.
If you want it in the form of a report, then you will need to increment paramter (be defautl the increment back is 1)
looking at the screenshot if you want the cumulative membership for 2018, you will need to go back 5 incrementsplease try the below formula in the custom summary formula
RowCount +
BLANKVALUE(PREVGROUPVAL(RowCount, CREATED_DATE,1),0) +
BLANKVALUE(PREVGROUPVAL(RowCount, CREATED_DATE,2),0) +
BLANKVALUE(PREVGROUPVAL(RowCount, CREATED_DATE,3),0) +
BLANKVALUE(PREVGROUPVAL(RowCount, CREATED_DATE,4),0) +
BLANKVALUE(PREVGROUPVAL(RowCount, CREATED_DATE,5),0)
you will have to change the formula for next year as you will hve entries for 2019
PS: This formula will not work as soon as you have one more entry under the Chapter Lookup, say you have one more entry for Dallas, TX under Chapter Lookup grouping, then the formula will be
RowCount +
BLANKVALUE(PREVGROUPVAL(RowCount, CREATED_DATE,1),0) +
BLANKVALUE(PREVGROUPVAL(RowCount, CREATED_DATE,2),0) +
BLANKVALUE(PREVGROUPVAL(RowCount, CREATED_DATE,3),0) +
BLANKVALUE(PREVGROUPVAL(RowCount, CREATED_DATE,4),0) +
BLANKVALUE(PREVGROUPVAL(RowCount, CREATED_DATE,5),0) +
BLANKVALUE(PREVGROUPVAL(RowCount, CREATED_DATE,6),0) + BLANKVALUE(PREVGROUPVAL(RowCount, CREATED_DATE,7),0) + BLANKVALUE(PREVGROUPVAL(RowCount, CREATED_DATE,8),0) + BLANKVALUE(PREVGROUPVAL(RowCount, CREATED_DATE,9),0) + BLANKVALUE(PREVGROUPVAL(RowCount, CREATED_DATE,10),0)
