How to obtain PERNR during BDC with PA40

Greetings!

I recorded a PA40 session and am using the code in my program with success. However, now I must make a call during the BDC code to a FM which requires the PERNR. I'm not sure how to obtain the PERNR while the BDC code is executing. I'm sure if I was doing it manually via PA40 I would be able to "see" the PERNR on the screens but I'm not sure how to obtain it while the BDC code is running.

Thanks in advance.

Snippet of code:

    ...
    PERFORM bdc_dynpro      USING 'MP000200'                '2010'.
    PERFORM bdc_field       USING 'BDC_CURSOR'              'Q0002-FATXT'.
    PERFORM bdc_field       USING 'BDC_OKCODE'              '=UPD'.
    PERFORM bdc_field       USING 'P0002-BEGDA'             lv_begda.
    PERFORM bdc_field       USING 'P0002-ENDDA'             '12319999'.
    PERFORM bdc_field       USING 'P0002-NACHN'             gt_enrollment-lname.
    PERFORM bdc_field       USING 'P0002-VORNA'             gt_enrollment-fname.
