    GellaiTamas,

    Create the following column in Vehicle_cost table.

    CheckTrailer = IF(ISERROR(SEARCH("Trailer",Vehicle_costs[Vehicle])),0,1)

    Then create the following measures in Vehicle_cost table.

    Measure = MAX(Uniform1[Annual])
    Uniform Cost = IF(MAX(Vehicle_costs[CheckTrailer])=1,0,[Measure]*[# of vehicle Value])

    Regards,
    Lydia

Anonymous,

 

Thing is that the 2 tables are not related. There are no columns which could be anyhow connected (they only have those 2 columns you can see).

 

User inputs:

- 'Country'[CountryName] - dropdown list (this comes from a 3rd table)

- 'Vehicle_costs'[Vehicle] - dropdown list

- number of vehicles - input value (I use a What-if scenario for this)

 

Then the number of vehicles entered is multiplied by the uniform cost ('Uniform1'[AnnualUniformCost]. This is easy and it works. Things don't work if I try to apply 0 as the uniform cost if "Trailer" is chosen as [Vehicle].

 

Expected result based on the tables I copied:

 

1.

Country: Canada

Vehicle: Hyundai HD72

Number of vehicles: 2

Uniform cost (Canada): 225,4 GBP

=>  225,4x2 = 450,8

 

2.

Country: Canada

Vehicle: Trailer

Number of vehicles: 2

Uniform cost (Canada): 225,4 GBP

=>  0 = 0 (because no uniform is needed for a trailer)

 

This should be a simple IF function with a SEARCH function - at least this is how it works in Excel (IF(ISERROR(SEARCH))).

I just can't figure out how to put it all together.

 

Thanks!

GellaiTamas,

Please check if the following DAX returns your expected result.

Uniform cost = IF(ISERROR(SEARCH("Trailer",'Vehicle_costs'[Vehicle])),CALCULATE(SUM('Uniform1'[Annual uniform cost]))*[# of vehicle Value],0)

Lydia

    Hi Lydia,

     

    Thanks for the code. Unfortunately it produces the following error:

    A single value for column 'Vehicle1' in table 'Vehicle_costs' cannot be determined. This can happen when a measure formula refers to a column that contains many values without specifying an aggregation such as min, max, count, or sum to get a single result.

     

    BR,

      GellaiTamas,

      Right click your table, choose "New Column" and apply the DAX.

      Regards,
      Lydia

        Hi Lydia,

         

        Unfortunately I get the same error message when applying the DAX for a new column.

         

        Thanks,

        Tamas
