+ - LIBREF (PK). The target libref.
+ - DSN (PK). The target table name.
+ - KEY_HASH (PK). This is a pipe seperated `md5()` hash of the primary key values - it uniquely identifies a single record.
+ - TGTVAR_NM (PK). Target variable name (32 chars)
+ - PROCESSED_DTTM.  The timestamp at which the record was processed.
+ - MOVE_TYPE. Either (A)ppended, (D)eleted or (M)odified
+ - IS_PK. Set to 1 if the variable is part of the primary key.
+ - IS_DIFF. For modified records, is 1 for a change and 0 for no change. Set to -1 for appends / deletes. 
+ - TGTVAR_TYPE. Either (C)haracter or (N)umeric
+ - OLDVAL_NUM. Old (numeric) value
+ - NEWVAL_NUM. New (numeric) value
+ - OLDVAL_CHAR. Old (character) value
