New to Discoverer have join/query question

Question

I have the following query; I am trying to import it but when I do, discoverer only brings in one of the two OUTAGE_FACTOR fields. Can I not just import this? I have the other joins set up ie fiscal year, plan id and unit. Do I need to set up the outer joins in the business area first? I'm assuming that is why it is not importing both fields.
SELECT prev_y.OUTAGE_FACTOR LY,
curr_y.OUTAGE_FACTOR FYTD,
outage.unit_nme,
outage.jul,
outage.aug,
outage.sep,
outage.oct,
outage.nov,
outage.dec,
outage.jan,
outage.feb,
outage.mar,
outage.apr,
outage.may,
outage.jun
FROM OUTAGE_MONTH_MX outage, OUTAGE_YEAR_MV curr_y, OUTAGE_YEAR_MV prev_y WHERE outage.l_year_fiscal_year = 2006 and outage.plant_id = 'FPP' and outage.l_year_fiscal_year = curr_y.L_YEAR_FISCAL_YEAR and outage.plant_id = curr_y.PLANT_ID and
outage.UNIT_NME = curr_y.UNIT_NME and outage.l_year_fiscal_year - 1 = prev_y.L_YEAR_FISCAL_YEAR(+) and outage.plant_id = prev_y.PLANT_ID(+) and
outage.UNIT_NME = prev_y.UNIT_NME(+)

Answer 1

Disco is also stripping the outer joins when I import the sql.
From sql inspector:
SELECT O100494.UNIT_NME, O100494.JUL, O100494.AUG, O100494.SEP, O100494.OCT, O100494.NOV, O100494.DEC, O100494.JAN, O100494.FEB, O100494.MAR, O100494.APR, O100494.MAY, O100494.JUN, O100535.OUTAGE_FACTOR
FROM STAR.OUTAGE_MONTH_MX O100494, STAR.OUTAGE_YEAR_MV O100535
WHERE ( ( O100494.L_YEAR_FISCAL_YEAR = O100535.L_YEAR_FISCAL_YEAR ) AND ( O100494.PLANT_ID = O100535.PLANT_ID ) ) AND ( O100494.UNIT_NME = O100535.UNIT_NME ) AND ( O100494.PLANT_ID = O100535.PLANT_ID ) AND ( O100494.L_YEAR_FISCAL_YEAR-1 = O100535.L_YEAR_FISCAL_YEAR ) AND ( O100494.UNIT_NME = O100535.UNIT_NME ) AND ( O100494.PLANT_ID = 'FPP' ) AND ( O100494.L_YEAR_FISCAL_YEAR = 2006 )
;
