Writing own event for Reservation creation BUS object

Question

I am trying to create a workflow that should get triggered when a new reservation is created for approval. I am using the BOR object for material reservation but it does not contain an event of creation. I wish to create a new event and then add code to the event so that a mail to an approver can be sent. Using the approval received I need to confirm the reservation else render it cancelled.
I require help in creating the event and writing the event code for it.
Thanks for taking time to go through my query

Hello Zankruti,
    Indeed, there's no such event for BUS2093. And if you try to do this to object BUS2093, you will come across error: "No change document object for business object type BUS2093".
    Given this, in your case, I am afraid that you will have to extend object BUS2093 by using delegation - then you will be able to add events CREATED or CHANGED, if necessary. Use transaction SWO1 to this, click on "settings" delegate, delegation type = ZBUS2093(for example) - you will delegate your ZBUS2093 type to BUS2093. After that, you will be able to create the events.                                                                               
Following the idea, I believe that the easiest way to do this is thorugh enhancement MBCF0007 (Customer function exit: Updating a reservation). Click on components, and then you will see EXIT_SAPMM07R_001. Within this exit, you can call SWE_EVENT_CREATE_IN_UPD_TASK (you trigger the events you will have created above).
