>I have a table where 3 character fields are combined to form the primary key. Because of the manner in which this table is now used (not as originally designed), a record can be deleted from the table by one user and later another user can add a record with the same key values. Auditing constraints require the deleted record (with datetime stamps) remain in the database; packing and recycling is not allowed.

Could you use this:
INDEX ON Field1_c + Field2_c + Field3_c .... FOR NOT DELETED()
