FM: HR_READ_INFOTYPE Problem

Question

Hi all you ABAP experts!
I'm working in a program (report mode) that has to read the data from an Infotype (in this case is IT0584) just after the IT has been created (by the same program, using CALL TRANSACTION). I am using the HR_READ_INFOTYPE FM as follows:
    CLEAR: p0584, p0584[].
    CALL FUNCTION 'HR_READ_INFOTYPE'
      EXPORTING
        pernr           = l_test_pernr
        infty            = l_infty
        "BYPASS_BUFFER   =  'X'
      TABLES
        infty_tab       = p0584
      EXCEPTIONS
        infty_not_found = 1
        OTHERS          = 2.
    " p0584 was declared using: INFOTYPES: 0584.
As you can notice the BYPASS_BUFFER parameter is commented. The "problem" is that I can see the record just created in SE16 but I can't get anything into p0584.
Now, if I uncomment the BYPASS_BUFFER I get the record(s) into p0584. Could anybody please explain me why this happens? How exactly does the BYPAS_BUFFER parameter is affecting p0584?
This really confuses me because I'm using the same FM without the BYPASS_BUFFER at the begining of the program for the same Infotype and successfully getting the existing records by that moment.
I will really appreciate if any can provide me the answer. Many thanks in advance!
