Hi @Hayashi87,

 

You can use the Generate Attribute operator : 

Here the process : 

<?xml version="1.0" encoding="UTF-8"?><process version="8.1.000">
  <context>
    <input/>
    <output/>
    <macros/>
  </context>
  <operator activated="true" class="process" compatibility="8.1.000" expanded="true" name="Process">
    <process expanded="true">
      <operator activated="true" class="read_excel" compatibility="8.1.000" expanded="true" height="68" name="Read Excel" width="90" x="112" y="34">
        <parameter key="excel_file" value="C:\Users\Lionel\Documents\Formations_DataScience\Rapidminer\Tests_Rapidminer\If_Or\If_Or.xlsx"/>
        <parameter key="imported_cell_range" value="A1:B10"/>
        <parameter key="first_row_as_names" value="false"/>
        <list key="annotations">
          <parameter key="0" value="Name"/>
        </list>
        <list key="data_set_meta_data_information">
          <parameter key="0" value="Carbrand.true.polynominal.attribute"/>
          <parameter key="1" value="Category.true.attribute_value.attribute"/>
        </list>
      </operator>
      <operator activated="true" class="generate_attributes" compatibility="8.1.000" expanded="true" height="82" name="Generate Attributes" width="90" x="313" y="34">
        <list key="function_descriptions">
          <parameter key="Category" value="if(Carbrand==&quot;BMW&quot;||Carbrand==&quot;Audi&quot;,&quot;A&quot;,&quot;B&quot;)"/>
        </list>
      </operator>
      <connect from_op="Read Excel" from_port="output" to_op="Generate Attributes" to_port="example set input"/>
      <connect from_op="Generate Attributes" from_port="example set output" to_port="result 1"/>
      <portSpacing port="source_input 1" spacing="0"/>
      <portSpacing port="sink_result 1" spacing="0"/>
      <portSpacing port="sink_result 2" spacing="0"/>
    </process>
  </operator>
</process>
