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"

     

     

    -----------------------------------------------------------

    Close and apply changes

Hi ERing 

 

Sorry about the path names. To be able to do this in Power Query, I first had to export the existing data and then import it into a new copy.

I made the assumption that all departments and all states would be in 'Table_A'.  If that isn't the case, it's not hard to change.


In Power Query:
- Make a reference to your 'Table_A'
- select the [Department] column
- remove duplicates
- rename to DimDepartment


- Make a reference to your 'Table_A'
- select the [State] column
- remove duplicates
- rename to DimState

 

Exit Power Query

 

I hope this makes sense.

The data I provided used Excel as a data source. The data in my real report uses Snowflake.

I'm unsure how I can create a DIM_Department table and a DIM_State table in Power Query using the tables I have loaded into Power BI from Snowflake.
