Wolfgang,

The reports are created by a third party tool and I don't think it recognizez the GTTs. I agree with you that changing attributes ot dictionary tables is not a very nice option too though

thank you

How about using GTTs rather than creating tables on the fly. Changing attributes of dictionary tables, if that's what you mean by increasing freelist, is a sure way for your database to become unsupported.
