  _select 'sflight : carrid connid fldate price currency + carrid = ''AC'' + connid = 820' r_sflight zap_null.
  _display r_sflight.

Example: Displaying data from table SCARR based on data from table SFLIGHT

INCLUDE zap.

START-OF-SELECTION.
  DATA: r_sflight TYPE REF TO DATA,
        r_scarr   TYPE REF TO DATA.

  _select 'sflight : *' r_sflight zap_null.
  _select 'scarr : * + carrid = <t>-carrid' r_scarr r_sflight.
  _display r_scarr.

ZAP supports custom ALV fieldcatalog and layout settings for fine-grained control over report display using the fields defined in the structures slis_fieldcat_alv and slis_layout_alv.

DEFINE FIELD CATALOG Syntax

_deffcat '<field1> <field2> ...'.

ADD FIELD CATALOG Syntax

_addfcat '''<field1>'' ''<field2>'' ...'.

DEFINE LAYOUT Syntax

_deflayout '<field1> <field2> ...'.

ADD LAYOUT Syntax

_addlayout '''<field1>'' ''<field2>'' ...'.

Example: Displaying data from table SFLIGHT using custom field catalog and layout

INCLUDE ZAP.

START-OF-SELECTION.
  DATA: R_SFLIGHT TYPE REF TO DATA.

  _SELECT 'sflight : carrid connid price' R_SFLIGHT ZAP_NULL.
  _DEFFCAT 'col_pos fieldname tabname seltext_m'.
  _ADDFCAT: '''1'' ''connid'' ''sflight'' ''Flight No.''',
            '''2'' ''carrid'' ''sflight'' ''Airline''',
            '''3'' ''price'' ''sflight'' ''Price'''.
