Dealing with Measure Totals

Ashish_Mathur the measure has notes in it where you see they "//".

basically i have one "DailyTotals" table that has three kinds of CostTypes, A,B,C.

CostTypeA= total cost where DailyTotals[ServiceDesciption]="p1"

CostTypeB= total cost where DailyTotals[ServiceDesciption]="p2"

CostTypeC= total cost where DailyTotals[ServiceDesciption] not in ("p1","p2")

flatcost=10

DailyTotals relates to a "Dates" table.

DailyTotals[Project]  is  used as a key to relate to another table "DTable". DTable[Name] is an attribute based on the project.  DailyTotals[Project]  is null for costTypeA but not CostTypeC.  For CostTypeB it can be null. 

Because CostTypeA often has no [Project] and therefor no DTable[Name], i need to conditionally over write the context to reapply CostTypeA based on DTable[Name] that had costTypeC in the respective month.

 CostTypeCMonthly% = CostTypeC / total CostTypeC number × 100 **this needs to be by month***

(total CostTypeA - flatcost) * CostTypeCMonthly%

Goal*obtain the monthly % share of CostTypeC where TypeC>0, multiply that by the total CostTypeA
