Dimension: 

WEEKSTART([Date])

Measure: 

RangeSum(Above(TOTAL COUNT({<Status={'New', 'Active'}, [WorkItemType]={'Bug'}>}DISTINCT [%ID]), 1, RowNo(TOTAL)))

And it's working in table, but i need to catch value from previous week like: 2020-10-12 212, 

and compare with current: 2020-10-19 219,  and that comparison should be in KPI, so when i don't have week start dimension cumulative measure stop working and I don't know how to do it 😞

To summarize: my expected result should be two measures: one current which i have, and one from previous (cumulative measure) . Thank you in advance.

Please Note, i am mostly interested how to do it in FrontEnd, right now i did it in BackEnd

@Micki This should be easy to do using set analysis. May be this for 2020-10-19

Count({<Status = {'New', 'Active'}, [WorkItemType] = {'Bug'}, Date = {"<=$(=Date(Max(Date)))"}>} DISTINCT [%ID])

and this for 2020-10-12

Count({<Status = {'New', 'Active'}, [WorkItemType] = {'Bug'}, Date = {"<=$(=Date(WeekStart(Max(Date), -1)))"}>} DISTINCT [%ID])

@sunny_talwar , OMG you change my mind how qlik is working :), thank you so much, never thought it can working in that way, i just made minor change for 2020-10-12:

Date(WeekStart(Max(Date), 2)
