create order with CHANGED_AT CREATED_AT old

Hi Gurus,

My requirement:

I have to do a massive load of orders with the fields CHANGED_AT and CREATED_AT old.

The thing is exist a table which doesn't allows me to changed CRMC_FIELDCHECK (and I cannot change)

Does anybody know how to create orders with filling this parameters with old date values.

Thanks in advance.

Regards.

Diego
