Hi,
I have a table of data which capture "Cumulative Expended Manhours" on every week. I need a column/measure that calculates the weekly value for each activty code on that week. example table as below. I have attached the sample Power Bi data as well.

Solved! Go to Solution.
| Thanks to the great efforts by MS engineers to simplify syntax of DAX! Most beginners are SUCCESSFULLY MISLED to think that they could easily master DAX; but it turns out that the intricacy of the most frequently used RANKX() is still way beyond their comprehension! |
DAX is simple, but NOT EASY! |

Hi,
This calculated column formula works
=Data[Cumulative Expended Manhours]-LOOKUPVALUE([Cumulative Expended Manhours],Data[Activity Code],Data[Activity Code],Data[Week End Date],CALCULATE(MAX(Data[Week End Date]),FILTER(Data,Data[Activity Code]=EARLIER(Data[Activity Code])&&Data[Week End Date]<EARLIER(Data[Week End Date]))))
Hope this helps.
