RE-FX: How to assign a rental space to an object group in a real estate contract

I’ve had a problem assigning a newly created rental space (cut out of a poolspace) to an object group.

I solved it and want to blog it to prevent other real estate developers from running into this mess with assigning rental objects to an object group.

At first, I was trying my luck with CL_REBD_OBJ_ASSIGN_MNGR_BO. But due to the fact, that there is only a interface available with OBJASSTYPE = ’10’ (Contract=>Object Group),


OBJASSTYPE IMPLIFNAME                                            GUIFMPBO                                XOBJASSTYPE        

10                   IF_REBD_OBJ_ASSIGN_MNGR_BO     REBD_GUI_OBJASS_BO_PBO   Vertrag => Objekt(gruppe)
11                                                                                   REBD_GUI_OBJASS_BO_PBO   Objektgruppe => Objekt  (Object Group => Rental Object)

Later I discovered, that the GUI is using using the class CL_RECN_OBJ_ASSIGN_MNGR_CN to accomplish what I wanted to do.

At first, I was not able to apply a method to do just that with objasstype 11.

As you can see in the table,  type 11 can only be handled in the GUI PBO Module. That’s why I wrote nearly a copy of the code I found there when I debugged the ‘+’ Button to add an object to the object group in the GUI.

Surprisingly there’s this simple insert_bus_object-method at the end of the code snippet that does the job.

Everything works fine in the insert_bus_object-method, it quits with sy-subrc = 0:


   METHOD add_rental_space_to_objgroup.

Checking the resulting contract with this rental space delivers in tab Objects the wanted hierarchy Object Group -> Rental Space.

Don’t forget to check_all, store and commit your data of the created contract object!

P.S.: I would have expected a method in the Object Group-Interface IF_REBD_OBJECT_GROUP or an Interface in TIVBDOBJASSTYPE like IF_REBD_OBJ_ASSIGN_MNGR_BO with OBJASSTYPE = 11 which does the job!
