CRM_ORDERADM_H_CHANGE_OW Return messages

Hi gurus,

I have a new scenario I don´t know how to solve it.

I've developed a new FM for updating CRM orders. This update is made calling CRM_ORDERADM_H_CHANGE_OW standard function.

As I see, this function doesn`t have any return table or parameters with messages. This FM use CRM_MESSAGE_COLLECT in order to store messages.

How can I recover this messages after execution of  CRM_ORDERADM_H_CHANGE_OW? My perfect scenario is to obtain returned messages (Class, number, id...) and return them to my FM caller.

Any ideas??

Thanks in advance!
