Hi,
the dump you are receiving is because method SET_USER_ID of class CL_CFX_USER is raising an exception (CX_CFX_OBJECT_NOT_EXISTING).
RAISE EXCEPTION TYPE cx_cfx_object_not_existing EXPORTING object_type = l_object_type object_id = l_id_str.
1.- Could you please go to se24 with the above information and do a check? what happens then?
2.- set a break-point before line 134 of the above class and method and execute again to see what is going on. Why is the exception raised?
The notes i pointed make reference to that method (check the correction instructions of 1766551)
Best regards,
Pablo
