Oracle Select Destinct Dups?

[dowlingm815]

the following code keeps generating duplicate row as:

POHD_CODE FY ACTIVITY_DATE USER_ID SPRIDEN_ID LAST_NAME ITEM COMM_DESC AMT COAS_CODE
P0469513 10 16-Nov-09 OBLISKD H00446436 Integra Radionics 1 n/a-Extended Warranty on RT Workstation 36285 1
P0469513 10 16-Nov-09 OBLISKD H00446436 Integra Radionics 1 n/a-Extended Warranty on RT Workstation 36285 1


Any insight would be appreciate?
