Is it possible to submit an abap oo instance?

Question

Hi experts,
I need to execute the process of creating 300.000 materials associated with 15 centres in background.
Is this possible? Apparently, I can't specify the instance of the class to the SUBMIT declarative... I would appreciate your responses.
Lots of thanks,
Javier

I don't know of any way to execute the instance method in the background, but I think you could call a custom FM in background. You could serialize object instance into XML (using CALL TRANSFORMATION statement) and pass the resulting XML string to the custom FM. In the FM, you can then use the CALL TRANSFORMATION statement to create an object from the XML string. Then you can call the method of the reconstructed instance.
Here's sample code (that I haven't tested, but should get you going in the right direction)
CLASS cl_class DEFINITION.
  PUBLIC SECTION.
  METHODS do_action.
  INTERFACES if_serializable_object. " <-- This is needed for CALL TRANSFORMATION to work!
ENDCLASS.
CLASS cl_class IMPLEMENTATION.
  METHOD do_action.
*   <--Do whatever the method needs to do here-->
  ENDMETHOD.
ENDCLASS.
FORM do_method.
  DATA: lr_instance TYPE REF TO cl_class.
  DATA: l_class_xml TYPE string.
  CREATE OBJECT lr_instance
* <--Do whatever you need to do to prepare instance here-->
  CALL TRANSFORMATION id SOURCE class = lr_instance RESULT XML l_class_xml.
  CALL FUNCTION 'CALL_METHOD' STARTING NEW TASK
    EXPORTING
      p_class_xml = l_class_xml.
ENDFORM.
FUNCTION call_method.
* IMPORTING
*   p_class_xml TYPE string.
  DATA: lr_instance TYPE REF TO cl_class
  CALL TRANSFORMATION id SOURCE XML p_class_xml RESULT class = lr_instance.
  CHECK lr_instance IS BOUND.
  lr_instance->do_action( ).
ENDFUNCTION.
