Calculations Struggle

FctTransData

FctBudget

So Budget for 1737 = 2018000 (for periods 1 - 4) (Yes I realise budget is 2019 bt it is being used for 2020 for now) and the budget selection is  a slicer

Transdata for this set is 36700

So, I need a measure I guess that would get me the variance (1981300)

I have tried a custom column in each fact table that gives me the YTD value and then tried a calculate(sum, filter 

I have tried a measure that is the same as above

but is just keep getting the wrong number in the variance)

so, supply group major which gives me entryid 1737

which gives me the appropriate budget data when i supply budget name and period

and similar for transdata (same filter of group major)   (in this example 1737 is expenses)

sorry if i am not explaining well

i need to supply the period, year and entry id for budget

then date range for for transdata
