TYPE-POOLS: slis.
DATA: BEGIN OF it_data OCCURS 0,
             vbeln LIKE vbak-vbeln,
             matnr LIKE mara-matnr,
          END OF it_data.
DATA: it_fieldcat TYPE slis_t_fieldcat_alv,
           it_lvcfcat TYPE lvc_t_fcat.
CALL FUNCTION 'REUSE_ALV_FIELDCATALOG_MERGE'
   EXPORTING
      i_program_name = sy-repid
      i_internal_tabname = 'IT_DATA'
      i_inclname = sy-repid
  CHANGING
     ct_fieldcat = it_fieldcat
  EXCEPTIONS
     inconsistent_interface = 1
     program_error = 2
     OTHERS = 3.
  IF sy-subrc NE 0.
     MESSAGE ID sy-msgid TYPE sy-msgty NUMBER sy-msgno
     WITH sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
  ENDIF.
 
CALL FUNCTION 'LVC_TRANSFER_FROM_SLIS'
  EXPORTING
     it_fieldcat_alv = it_fieldcat
  IMPORTING
     et_fieldcat_lvc = it_lvcfcat
  TABLES
    it_data = it_data
  EXCEPTIONS
    it_data_missing = 1
    OTHERS = 2.
  IF sy-subrc NE 0.
