Comparing values two different tables

I have two tables joined on an ID column.  Both tables have a similar field called "Practice", and I need to check if the values are the same.  I am trying to use the EXACT function, but when I choose my first field from Table1, it doesn't allow me to pick the second field from TAble2.  How do I compare strings of two fields from two different tables?

    Hi! Anonymous 

    The EXACT function doesnt compare values from two table.

    Can you give more information on your Goal.

     

    You can try making a join with Power Query.

    = Table.Join(Table1, "Practice", Table2, "Practice")

     

    If I solved your problem please consider marking this as a solution.

      It is basically a quality control check.  TAble A is from one system, and table B is from another system.  Both tables "should" have the same practice name per ID, but they don't always.  So I need to find where they don't match so we can do a clean-up.

        You can try like the following example, these two tables will show rows of one table which do not appear in another table.

        Table 1 = EXCEPT(VALUES(Employees1[FirstName]),VALUES(Employees2[FirstName]))

        Table 2 = EXCEPT(VALUES(Employees2[FirstName]),VALUES(Employees1[FirstName]))

    I am not sure if you are trying a measure, in that case use LOOKUPVALUE function.
    If you generate a table try INTERSECT or EXCEPT

    Anonymous  - Use RELATED or something like MAXX(RELATEDTABLE(...),[2nd Column]).
