PROGRAM trans_routine.
      CLASS routine DEFINITION
CLASS lcl_transform DEFINITION.
  PUBLIC SECTION.
Attributs
    DATA:
      p_check_master_data_exist
            TYPE RSODSOCHECKONLY READ-ONLY,
*-    Instance for getting request runtime attributs;
    Available information: Refer to methods of
    interface 'if_rsbk_request_admintab_view'
      <b>p_r_request
            TYPE REF TO if_rsbk_request_admintab_view READ-ONLY.</b>
<i>The bold area above where you get the requestid, here I am stuck.
The below code does not bring the correct requestid of PSA</i>
CALL METHOD P_R_REQUEST->GET_REQUID30
      RECEIVING
        R_REQUID30 = IREQUID.
    CALL METHOD P_R_REQUEST->GET_REQUID
      RECEIVING
        R_REQUID = IREQUID.
    SELECT FILENAME INTO IFILENAME FROM rsseldone WHERE rnr =  IREQUID  AND lnr = '        1'.
Hope this can give a better picture where I am currently stuck not able to get the PSA request id in the <b>start routine of transformation</b> to read the data and filename from there.
Thanks alot
