Improve the performance of Measure Formula

[jesly_ajin]

I will need your support to improve performance for the below measure formula. This is taking too much time to execute.

ActualEqHours = CALCULATE (
SUMX ( SelfService_Plan_DailyPlanHour, IF(SelfService_Plan_DailyPlanHour[DailyPlanStatusId]=1,0,
IF(SelfService_Plan_DailyPlanHour[DailyPlanStatusId]=2,SelfService_Plan_DailyPlanHour[ActualStdHours],
if(SelfService_Plan_DailyPlanHour[DailyPlanStatusId]=3,SelfService_Plan_DailyPlanHour[ApprovedStdHours],SelfService_Plan_DailyPlanHour[ApprovedStdHours])))),
FILTER ( SelfService_Plan_DailyPlanHour,
SelfService_Plan_DailyPlanHour[IsActive_Hour]
&& SelfService_Plan_DailyPlanHour[IsLatest]
&& SelfService_Plan_DailyPlanHour[ResourceTypeDescription]="Equipment"
&& (SelfService_Plan_DailyPlanHour[DailyPlanStatusDescription]="Approved" || SelfService_Plan_DailyPlanHour[DailyPlanStatusDescription]="Awaiting Approval")
&& RELATED(SelfService_Control_CostItem[Is_terminal])
&& SelfService_Plan_DailyPlanHour[ProjectId]=RELATED(SelfService_Core_Project[Project_id])
),USERELATIONSHIP(SelfService_Plan_DailyPlanHour[ProjectIdEquipDisplay], InEightProjEquipmentStagingTable[ProjectIdEquipmentDisplay]))

Hi  @jesly_ajin ,

Variables can be defined, I modified Dax like this, you can add it to your PBIX file to view the time spent:

ActualEqHours =
var _1=
SWITCH(
    TRUE(),
SelfService_Plan_DailyPlanHour[DailyPlanStatusId]=1,0,
SelfService_Plan_DailyPlanHour[DailyPlanStatusId]=2,SelfService_Plan_DailyPlanHour[ActualStdHours],
SelfService_Plan_DailyPlanHour[DailyPlanStatusId]=3,SelfService_Plan_DailyPlanHour[ApprovedStdHours],
SelfService_Plan_DailyPlanHour[ApprovedStdHours])

var _2=SUMX(SelfService_Plan_DailyPlanHour,_1)

return
CALCULATE ( _2,
FILTER ( SelfService_Plan_DailyPlanHour,
SelfService_Plan_DailyPlanHour[IsActive_Hour]
&& SelfService_Plan_DailyPlanHour[IsLatest]
&& SelfService_Plan_DailyPlanHour[ResourceTypeDescription]="Equipment"
&& (SelfService_Plan_DailyPlanHour[DailyPlanStatusDescription]="Approved" || SelfService_Plan_DailyPlanHour[DailyPlanStatusDescription]="Awaiting Approval")
&& RELATED(SelfService_Control_CostItem[Is_terminal])
&& SelfService_Plan_DailyPlanHour[ProjectId]=RELATED(SelfService_Core_Project[Project_id])
),USERELATIONSHIP(SelfService_Plan_DailyPlanHour[ProjectIdEquipDisplay], InEightProjEquipmentStagingTable[ProjectIdEquipmentDisplay]))
