DBMSs tend to vary in their implementation of the SQL UPDATE statement when it involves updating columns to values found in other tables. Try using a fairly generic correlated sub-query, such as this one:
UPDATE F03012 SET F03012.AIMAN8 = (SELECT ABAN84 FROM F0101 WHERE F0101.ABAN8 = F03012.AIAN8) WHERE F0101.ABAT1 = 'C';
