Is this simple Data Model correct?

I have a report currently set up with the data model below. I have two tables (Table_A, Table_B) and I need my report to show a table visual with measures from both tables.   I usually try to have ...

    In Power Query, Create query "DIM_STATE" as below:

    let 
    Source = Table_A,
    #"Removed Other Columns" = Table.SelectColumns(Source,{"State"}), 

    Source1 = Table_B,
    #"Removed Other Columns1" = Table.SelectColumns(Source1,{"State"}), 

    SourceCombined = Table.Combine({#"Removed Other Columns", #"Removed Other Columns1"}),
    #"Removed Duplicates" = Table.Distinct(SourceCombined),
    #"Filtered Rows" = Table.SelectRows(#"Removed Duplicates", each [State] <> null and [State] <> "" and [State] <> "null")
in
    #"Filtered Rows"

    Output:

    Similarly for "DIM_DEPARTMENT"

    let 
    Source = Table_A,
    #"Removed Other Columns" = Table.SelectColumns(Source,{"Department"}), 

    Source1 = Table_B,
    #"Removed Other Columns1" = Table.SelectColumns(Source1,{"Department"}), 

    SourceCombined = Table.Combine({#"Removed Other Columns", #"Removed Other Columns1"}),
    #"Removed Duplicates" = Table.Distinct(SourceCombined),
    #"Filtered Rows" = Table.SelectRows(#"Removed Duplicates", each [Department] <> null and [Department] <> "" and [Department] <> "null")
in
    #"Filtered Rows"

I think, you may need to do in Power Query create two tables (dims):

  • Unique values of Department from both tables
  • Unique values of State from both tables

 

In the data model use these two to join to the transaction data (aka facts)

 

In the visuals, use these two table for slicer!

 

Typical Fact - dim model approach.

 

Thanks

    Thanks sevenhills 

    Can you provide any guidance on how to create the table of unique values from Department table and the tables of unique values from the State table?
