Help about the definition of new task.

Question

Hi,
I can start successfully a Bex Query via FM abap4_call_transaction but I see two queries defining this call:
CALL FUNCTION 'ABAP4_CALL_TRANSACTION'
STARTING NEW TASK 'ZTRX'
EXPORTING
TCODE = 'ZTRX'
EXCEPTIONS
TCODE_INVALID = 1
OTHERS = 2.
My tests:
1) Without defining a specific "task" but referring to a transaction code ZTRX, the call to a FM work correctly but the effect is to start two times the program/report defined for the transaction ZTRX. I have created the transaction ZTRX as copy of RRMX (se93).
2) I tried to definine a "task" (PFTC, PFTC_INS, PFTR, PFTS) but I find some difficulty and I don't know if this step is necessary. Certainly, defining a generic name, the call to a FM don't work correctly.
3) At the last I tried to use:
CALL METHOD cl_reca_gui_services=>call_transaction
          EXPORTING
            id_tcode             = 'ZTRX'
           IF_LEAVE_CURRENT     = ABAP_FALSE
           IF_SKIP_FIRST_SCREEN = ABAP_FALSE
            if_new_external_mode = abap_true
          EXCEPTIONS
            error                = 1
            OTHERS               = 2.
trying to start only one session (as /oZTRX), but I receive un error because the method is not found.
Any help will be appreciated. Thanks in advance.

Hi Giovanni
It's not very clear your problem, I wrote this simple code and it works fine (not twice running):
CALL FUNCTION 'ABAP4_CALL_TRANSACTION' STARTING NEW TASK 'TEST'
  EXPORTING
    TCODE = 'FB03'
  EXCEPTIONS
    TCODE_INVALID = 1
    OTHERS = 2.
