Hi Everyone,

im having issues converting the Tableau LOD's to DAX. Can someone help me with the below expressions? Thanks!

Cummulative Actual =

if isnull(sum([actual])) then null

else running_sum(sum([actual])) 

end 

Running Sum Actual = 

If not isnull(sum([actual through last week])) then running_sum(sum([actual through last week])) end
