migrating from dBASE to IB

I migrate my datas from dBASE tables to IB with DataPump. Some of the tables was migrated successfully into IB, but some of them not and in these cases i received the following error message.

Metadata update statement is not allowed by the current database SQL dialect,
(maybe that the SQL warning code = 301 belongs to this message too)

What is the reason - and the solution ?

Thanx,

Check the fieldnames in the suspected tables.
If the fieldnames are IB keywords, it will not
pump...
