允许在带有下拉菜单的 ALV 网格单元格中使用自由文本

Question

我已经为 ALV 网格单元格设置了一个下拉列表。下拉窗口工作正常，但它只允许从下拉值列表中输入值。是否可以允许在单元格中自由输入文本？

我的 ABAP 代码是：

正在创建值列表：

DATA: lt_dropdown TYPE lvc_t_dral,
      ls_dropdown TYPE lvc_s_dral.
data: ls_taba TYPE dd07v,
      lt_taba TYPE STANDARD TABLE OF dd07v,
      lt_tabb TYPE STANDARD TABLE OF dd07v.

CALL FUNCTION 'DD_DOMA_GET'
  EXPORTING
    DOMAIN_NAME         = 'ZBC_TRADE_NETWORK'
    LANGU               = SY-LANGU
    WITHTEXT            = 'X'
 TABLES
    DD07V_TAB_A         = lt_taba
    DD07V_TAB_N         = lt_tabb
 EXCEPTIONS
    ILLEGAL_VALUE       = 1
    OP_FAILURE          = 2
    OTHERS              = 3
        .

 IF SY-SUBRC <> 0.
   return.
 ENDIF.

loop at lt_taba into ls_taba.
  ls_dropdown-handle = '1'.
  ls_dropdown-int_value = ls_taba-domvalue_l.
  ls_dropdown-value = ls_taba-ddtext.
  APPEND ls_dropdown TO lt_dropdown.
endloop.

*method to display the dropdown in ALV
CALL METHOD go_grid->set_drop_down_table
  EXPORTING
    IT_DROP_DOWN_ALIAS = lt_dropdown.

填写字段目录：

data: ls_fcat type lvc_s_fcat,
      lt_fcat type lvc_t_fcat.

field-symbols: <lfs_fcat> type ls_fcat.

call function 'LVC_FIELDCATALOG_MERGE'
    exporting
      i_structure_name = gc_struct_name
    changing
      ct_fieldcat      = lt_fcat
    exceptions
      others           = 1.

loop at lt_fcat assigning <lfs_fcat>.
  case <lfs_fcat>-fieldname.  
    when 'NETWORK'.
      <lfs_fcat>-drdn_hndl = '1'.
      <lfs_fcat>-drdn_alias = 'X'.
      <lfs_fcat>-edit = abap_on.
  endcase.
endloop.

设置显示的 ALV 网格

go_grid->set_table_for_first_display(
  exporting
    i_save               = lf_save
    i_default            = lf_default
    is_variant           = ls_vari
    is_layout            = ls_layo
    it_toolbar_excluding = lt_excl
  changing
    it_outtab            = <lfs_t_data>
   it_fieldcatalog       = lt_fcat
  exceptions
    others               = 1
).

没有。下拉字段表示固定值集。如果您想同时拥有值目录和文本编辑工具，请使用值帮助（F4 帮助）来实现目录访问。
