ABAP 输出方式详解编程语言

1.使用宏方式，如下：

DEFINE ADD_FIELD.
  I_FIELDCAT-TABNAME = &2.
  I_FIELDCAT-FIELDNAME = &1.
  I_FIELDCAT-SELTEXT_M = &4.
  I_FIELDCAT-OUTPUTLEN = &3.
  I_FIELDCAT-INPUT = &5.
  I_FIELDCAT-HOTSPOT = P_CHAR.
  APPEND I_FIELDCAT.
END-OF-DEFINITION.

DEFINE DISPLAY_DATA.

    MOVE SLIS_EV_USER_COMMAND TO L_LS_EVENT-FORM.
    APPEND L_LS_EVENT TO I_EVENTS.
  ENDIF.
