Business Object for asset accounting/capitalization

Hello frineds,

I need to develop a work flow to notify IO owner when IO status changes to RELEASED.

my workflow needs to be triggered once we save the internal order.

1) I am not getting any Business Object for this asset accounting. do u have any suggestion?

2) Can u tell me how to save the internal order through which my workflow is getting triggered?

My requirement is to use the transaction * CJ92 , CJ20N, ko02 or ko04 * for changing the IO status to released.

Thanks,

Romanch
