    Hi Glory1891 ,

    Below is my 2019 table:

    Below is my 2018 table:

    First , you need to configure the relationship for the two tables:

    The following DAX might work for you:

    Measure = 
   var p_2018 = SELECTEDVALUE('2018'[Som value])
   var p_2019 = SELECTEDVALUE('2019'[Som value])
   var result = 
       CALCULATE(
         p_2019 - p_2018,
         ALL('2018'[Product])
       )
    return result

    The final output is shown in the following figure:

    Best Regards,

    Xianda Tang

We want to help you but your description is too vaugue. Please write it again clearly.

Please DON'T copy & paste your dax and reports that does not work and expect us to fathom what you want to do. That is a bit crazy. 😀

Please just give a simple non technical functional decscription of what you want, then let us suggest the solution. Thank you.

Provide example input data as table text (not a screen print) so we can import the data to build a solution for you.
Also provide the example desired output, with a clear description of the process flow.
Remember not to share private data ... we don't want you to get into trouble. 😧
Take time and care to use the same table and field names in the input, output and description so we can understand your problem and help you.
Try keep it simple and ask one question per ticket.
You will get a quick response if you put time, care and effort into writing clear problem descriptions.

Vaugue descriptions can waste your time and ourtime.

Look foward to helping you when the above information is forthcoming
