Is this better?
select DISTINCT FIRST_NAME||' '||LAST_NAME display_value
      , ROW_ID return_value
  from "PSA_RESOURCE_MANAGER"
where PSA_RESOURCE_MANAGER.ACTIVE_FLAG='Y'
   AND :P117_REPORTING_MANAGER = PSA_RESOURCE_MANAGER.REPORTING_MANAGER
   AND :P117_REPORTING_MANAGER <> -1 order by 1or
select DISTINCT FIRST_NAME||' '||LAST_NAME display_value
      , ROW_ID return_value
  from "PSA_RESOURCE_MANAGER"
where PSA_RESOURCE_MANAGER.ACTIVE_FLAG='Y'
   AND :P117_REPORTING_MANAGER = PSA_RESOURCE_MANAGER.REPORTING_MANAGER
   AND :P117_REPORTING_MANAGER != '-1' order by 1Is ROW_ID a column in your table by the way? If not, you should use ROWID (without the underscore)
