PhycialTableMap value when creating a dataset of datasets using CreateDataSet API

I don't know if it will be a reference for API key parameters, but it's an excerpt of the code I used to create a dataset with CloudFormation.

  # QuickSight DataSet
  RepDataSet:
    Type: AWS::QuickSight::DataSet
    Properties:
      AwsAccountId: !Ref AWS::AccountId
      Name: 'Join-Company'
      DataSetId: 'Join-Company-Id'
      ImportMode: SPICE
      PhysicalTableMap:
        rep-physical:
          RelationalTable:
            DataSourceArn: !GetAtt AthenaDataSource.Arn
            # Set Database Name
            Schema: 
              Fn::ImportValue:
                !Sub "${Env}-GlueDatabase-Name"
            # Set Table Name
            Name: !Ref RepTable
            InputColumns:
              - Name: source
                Type: STRING
              - Name: destination

        id-physical:
          RelationalTable:
            DataSourceArn: !GetAtt AthenaDataSource.Arn
            # Set Database Name
            Schema: 
              Fn::ImportValue:
                !Sub "${Env}-GlueDatabase-Name"
            # Set Table Name
            Name: !Ref IdTable
            InputColumns:
              - Name: id
                Type: STRING
              - Name: name
