       ROW_NUMBER() OVER(PARTITION BY ma.Description ORDER BY iol.M_product_id DESC) rn 
       FROM M_inoutline iol 

       inner join M_inout mi ON (iol.m_inout_id = mi.m_inout_id) 
       inner join C_Order co ON (co.c_order_id = mi.c_order_id) 
       inner Join M_AttributeSetInstance ma ON (ma.m_attributesetinstance_id =iol.m_attributesetinstance_id) 
       inner join M_Product mp ON (mp.m_product_id = iol.m_product_id) 
      where mp.m_product_category_id= 1000447 AND mi.issotrx = 'Y';

對於我來說,它看起來你想做的事:

select * from (/*YOUR QUERY*/) where rn = 1;
