sum measure from different cards

Hi  DECRE83 
Welcome to the Microsoft Fabric Forum,

Regarding the measure to sum only the selected steps for the transportation route:

Since all step costs are stored in a single table, and the requirement is for the total to reflect only the steps selected through the slicers, a measure should be created that dynamically respects the current filter context.

Use SUMX function :

DAX:

Total Selected Route Cost = 
SUMX( VALUES(Table[StepID]), 
CALCULATE(SUM(Table[StepCost])) )

If steps are uniquely identified by multiple columns (category, location1,location2) adjust the measure:

DAX:

Total Selected Route Cost = 
SUMX( 
SUMMARIZE( Table, 
Table[Category], 
Table[Location1], 
Table[Location2] ), 
CALCULATE(SUM(Table[StepCost])) )
