Por que no funciona el distinct
SELECT DISTINCT G.IDGERENCIA, GS.AREA
  FROM TA_GASTOS_STAGE GS
       INNER JOIN TA_GERENCIA G ON GS.GERENCIA_DIRECCIÓN = G.NOMBREGERENCIA
WHERE
       GS.AREA LIKE '%Mantenimiento Palmas%'  
ORDER BY G.IDGERENCIA,GS.AREA

         IDGERENCIA      AREA
1      11      Mantenimiento Palmas
2      11      Mantenimiento Palmas

this is the table_stage
SELECT *
  FROM TA_GASTOS_STAGE GS
WHERE
       GS.AREA LIKE '%Mantenimiento Palmas%'

try this to see if you have extra invisible white space


SELECT DISTINCT G.IDGERENCIA, GS.AREA, length(gs.area)
  FROM TA_GASTOS_STAGE GS
       INNER JOIN TA_GERENCIA G ON GS.GERENCIA_DIRECCIÓN = G.NOMBREGERENCIA
WHERE
       GS.AREA LIKE '%Mantenimiento Palmas%'  
ORDER BY G.IDGERENCIA,GS.AREA

try this...


update  TA_GASTOS_STAGE set area = trim(area)

or, to only remove trailing blanks

update  TA_GASTOS_STAGE set area = rtrim(area)
