I have multiple measures :

ServicerevenueA = CALCULATE(SUM(revenue_table[total]),revenu_table[service]= "Service A")

Total revenue = SUM(revenue_table[total])

PercentageA = [servicerevenueA]/[total revenue]

Service expense = CALCULATE(SUM(expense_table[total]),expense_table[eligible for service revenue] = "true")

ExpenseA = [PercentageA] * [serviceexpense]

you can see the following numbers here :

on october 4 :

on October 5 :

as you see no issues with my calculations

but when i select both dates:

you can see that it shows sum of expense A is 176.81

but if you sum them manually, 
october 4 expenseA = 163.58
October 5 expenseA = 32.63

sum should be 196.21 and not 176.81

what should i do?

@Anonymous , You need some common row level field for this

ExpenseA = [PercentageA] * [serviceexpense]

Like sumx(Values(DIm[Customer]), calculate([PercentageA] * [serviceexpense]))
