R12 - customer profile > Drill Down

We have the following profile variable setup but when we call up the variable to map the drill down we get "FRM-40831: Truncation Occurred: Value too long for field ALIAS_NAME"

Any way around this?

SELECT count(ps.attribute1)+count(ps.attribute2)+count(ps.attribute3)

FROM hz_party_sites ps,

          (SELECT distinct person_id FROM per_all_people_f) A,

          (SELECT distinct person_id FROM per_all_people_f) b,

          (SELECT distinct person_id FROM per_all_people_f) c

Where ps.party_id = :party_id

AND ps.party_site_id = :party_site_id

AND ps.attribute1 = A.person_id (+)
