Is this simple Data Model correct?

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"
