Calculating the same value in 2 different columns

Hi All,

 

I am new to Power BI and think it is a great analysis tool.  I am attempting to create a report but I am facing issues (due to being new to the tool).

 

The intention of the report is to show the number of imports (column 1) and the number of exports (column 2) from a specific shipping port (location) for a given customer (row 1).

 

This mean that the port needs to be selected before the report is generated.

 

Once the port has been chosen, then this value needs to be checked against every record in the customer table looking at the 'import' and 'export' columns.  If the chosen port matches either the import or export values then this should be counted else it should not be counted. 

 

Here is an example:

This is how the underlying data looks:

ConsigneeImportExport
Customer 1LISNYC
Customer 2NYCLEI
Customer 3LEINYC
Customer 4NYCLIS
Customer 5LEINYC
Customer 6NYCLIS
Customer 7LEINYC
Customer 8LEINYC
Customer 9LEINYC
Customer 10NYCLIS

 

So if the 'Port' was selected as 'LIS' then the following values should be returned:

PortLIS 
CustomerImportsExportsTotal
Customer 11 1
Customer 4 11
Customer 6 11
Customer 10 11
Total134

 

Can anyone give me some pointers on how I can calculate the chosen port against the I'mport' and 'Export' columns in the underlying data table?

 

Thank you in advance.

    2. Here's a sample .pbix for you.

     

    You need to unpivot your import and export columns (this is done in Edit Queries). This allows a much cleaner measure setup:

     

    // DAX
    // Measures
    
    Total =
    COUNTROWS( FactShipment )
    
    Imports =
    CALCULATE(
        [Total]
        ,FactShipment[ShipmentType] = "Import"
    )
    
    Exports =
    CALCULATE(
        [Total]
        ,FactShipment[ShipmentType] = "Export"
    )
