When generating the subset scripts, adding the merge script in the options, and applying the option "Use Table Orders", the import script generates the commands of the import in a correct order In the merge .bat script. The import commands are Ok, but in commands of the merge (sqlplus) it generates a different order (default). The subset doesn't use the table order defined by GT DataMaker in the merge. When I execute the merge.bat, it imports in the temporal schema Ok, but when it executes the sqlplus commands, it generates FK errors, because it does a commit every sqlplus process finish, and the order is different.
