Compare values from two dynamically selected columns

Hello! I am stuck with the following task:

 

I have a much bigger version of this sample table:

 

AttributeProduct 1Product 2Product 3Product 4
Length13124532
Width2332112
Height1551211
UoM Dimensionmmmmmmmm
Net Weight25242521
Gross Weight41254150
UoM Weightgggg

 

The task is to compare determine difference between the values for two dynamically selected products. 

 

Steps I have taken: 

1. I have duplicated my table

2. Created a relationship 1 to 1 between the two tables using the Attribute column

3. I have created 2 parameters 

Select Product A = {
    ("Product 1", NAMEOF('Table'[Product 1]), 0),
    ("Product 2", NAMEOF('Table'[Product 2]), 1),
    ("Product 3", NAMEOF('Table'[Product 3]), 2),
    ("Product 4", NAMEOF('Table'[Product 4]), 3)
} 
 
And 
 
Select Product B = {
    ("Product 1", NAMEOF('Table 2'[Product 1]), 0),
    ("Product 2", NAMEOF('Table 2'[Product 2]), 1),
    ("Product 3", NAMEOF('Table 2'[Product 3]), 2),
    ("Product 4", NAMEOF('Table 2'[Product 4]), 3)
}
4. Created a table visual where I have added Attribute, Select Product A and Select Product B and the result is the desired one. 
 
Now, I would like to create a measure or a calculated column that would calculate the difference in percentages between the values on each row for the products selected in the slicers (single select). If the value is not a number, "-" must be displayed
 
Appreciate any help I could get.
 
Thank you!

    Hi, alinamarinbadea 

    Thanks for amitchandak's reply. You can try the way from the link, or try to change the data model and then use the following dax.



    let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45W8knNSy/JUNJRMjQGEUZAwsQUSBgbKcXqRCuFZ6aAZY2MIWJAJYYgLljSIzUzPaMEJAbSYQrTD1QBkg3N91VwycxNzSvOzM8DCufmohMgVX6pJQrhMHOMQGYYmcBZEIPci/KLixGKTAxh8mCWqQHcNriSdBQcGwsA", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Attribute = _t, #"Product 1" = _t, #"Product 2" = _t, #"Product 3" = _t, #"Product 4" = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Attribute", type text}, {"Product 1", type text}, {"Product 2", type text}, {"Product 3", type text}, {"Product 4", type text}}),
    #"Unpivoted Columns" = Table.UnpivotOtherColumns(#"Changed Type", {"Attribute"}, "Attribute.1", "Value"),
    #"Renamed Columns" = Table.RenameColumns(#"Unpivoted Columns",{{"Attribute.1", "Product"}}),
    #"Filtered Rows" = Table.SelectRows(#"Renamed Columns", each ([Value] <> "g" and [Value] <> "mm")),
    #"Changed Type1" = Table.TransformColumnTypes(#"Filtered Rows",{{"Value", Int64.Type}})
in
    #"Changed Type1"
    First Product = 
VAR _min =
    CALCULATE (
        SELECTEDVALUE ( 'Product'[Value] ),
        FILTER ( 'Product', 'Product'[Product] = MIN ( 'Product'[Product] ) )
    )
RETURN
    _min

Second Product =
VAR _max =
    CALCULATE (
        SELECTEDVALUE ( 'Product'[Value] ),
        FILTER ( 'Product', 'Product'[Product] = MAX ( 'Product'[Product] ) )
    )
RETURN
    _max

diff % = 
VAR _firstProduct =
    CALCULATE (
        SELECTEDVALUE ( 'Product'[Value] ),
        FILTER ( 'Product', 'Product'[Product] = MIN ( 'Product'[Product] ) )
    )
VAR _secondProduct =
    CALCULATE (
        SELECTEDVALUE ( 'Product'[Value] ),
        FILTER ( 'Product', 'Product'[Product] = MAX ( 'Product'[Product] ) )
    )
RETURN
    DIVIDE ( _secondProduct, _firstProduct )
