Two different conditions for ALV and Excel output

Hello.

I have a job to make Selection screen with two radio buttons for ALV and Excel output and there are two different conditions for every output with different columns. How to make two different outputs? Now it`s making all of two outputs in one viev.

Here`s my code:

*&---------------------------------------------------------------------*

*& Report  ZTASK2_REPORT

*&---------------------------------------------------------------------*



REPORT ztask2_report.



TABLES: aufm, caufv.



TYPES: BEGIN OF my_tab,

  mblnr TYPE aufm-mblnr,

  matnr TYPE aufm-matnr,

  shkzg TYPE aufm-shkzg,

  menge TYPE aufm-menge,

  dmbtr TYPE aufm-dmbtr,

  ktext TYPE caufv-ktext,

  erdat TYPE caufv-erdat,

  auart TYPE caufv-auart,

END OF my_tab.



DATA: gt_aufmcaufv TYPE TABLE OF my_tab.



***Excel

DATA:

  lo_table TYPE REF TO cl_salv_table,

  lx_xml   TYPE xstring.
