Product builder compile error

[alek_frm]

Hi,
when create new model in product builder get error like this:
Unable to save . Unable to save Class Class1 . Id out of range 1 65535.
we save models in USR layer. class id range in usr layer is 50.000-60.000. we have about 40.000 models.
How can I save PB models in database (like Axapta 3.0)?
