It appears that Schema Compare does not support table types as columns. I have a table that had a type type added to it on dev. I compared it with QA and it correctly detected the difference, however, the migration script did not include the storage clause necessary for deployment. The statement it created is this:

ALTER TABLE xxproduct.auditlog ADD (auditvalue xxproduct.auditvaluetab);

It should have created something along these lines:

ALTER TABLE xxproduct.auditlog ADD (auditvalue xxproduct.auditvaluetab)
NESTED TABLE "AUDITVALUE" STORE AS "AUDITVALUES"
(PCTFREE 10 PCTUSED 40 INITRANS 1 MAXTRANS 255 LOGGING

TABLESPACE "XXTSTX_DATA" ) RETURN AS VALUE;
