BAPI_ACC_DOCUMENT_CHECK

Question

Dear experts,
We need help in one of the BAPI's BAPI_ACC_DOCUMENT_CHECK to post document.
BAPI working successfully if company code at header and item level is same but if items are from different company codes then we received error saying "Required fieldsOBJ_TYPE, OBJ_KEY, OBJ_SYS are blank.".
When searched forums on this, we found these fields are not mandatory however we receive the error message.
Also, found many threads on this but didnt get a proper link as to how can we proceed to resolve this issue.
Can you please help us if any data we entered is incorrect or we are missing with some functional configuration.
Thanks for your time.

Try to check the routine check_and_fill_acc_document, here you should see the following code:
IF document_header-obj_type = 'BKPFF'.
    PERFORM append_msg_to_return
            USING 'E'              "TYPE
                  'RW'             "ID
                  '628'            "NUMBER
                  'BKPFF'          "MESSAGE_ONE
                  'DOCUMENTHEADER' "MESSAGE_TWO
                  'DOCUMENTHEADER' "PARAMETER
                  1                "ROW
                  'OBJ_TYPE'.      "FIELD
  ENDIF.
  IF document_header-obj_type  IS INITIAL AND
     document_header-obj_key   IS INITIAL AND
     document_header-obj_sys   IS INITIAL AND
     document_header-ac_doc_no IS INITIAL.
    LOOP AT account_gl WHERE NOT stat_con  IS INITIAL
                          or NOT ac_doc_no IS INITIAL.
      EXIT.
    ENDLOOP.
    IF NOT sy-subrc IS INITIAL.
      PERFORM reference_create_prelim
              CHANGING document_header-obj_type
                       document_header-obj_key
                       document_header-obj_sys.
      document_header-bus_act = 'RFBU'.                "note1045412
    ENDIF.
  ENDIF.
The routine reference_create_prelim should be called and those fields should be filled
