一、以下拉菜单方式实现
1、效果截图如下
2、实现
1）、在fieldcat里设置F4的DRDN_HNDL值，该值类似索引号
2）、设置下拉值列表：通过类CL_GUI_ALV_GRID调用方法SET_DROP_DOWN_TABLE，该方法中参数IT_DROP_DOWN里有HANDLE列，该列的值对应1）设置的
DRDN_HNDL值
3、代码
1）、设置fieldcat属性
CASE PS_FIELDCAT-FIELDNAME.
WHEN 'RQCAT_DESC'.
PS_FIELDCAT-DRDN_HNDL = '1'.
WHEN 'RQTYP_DESC'.
PS_FIELDCAT-DRDN_HNDL = '2'.
WHEN 'AMTYP_DESC'.
PS_FIELDCAT-DRDN_HNDL = '3'.
WHEN 'FREPY_DESC'.
PS_FIELDCAT-DRDN_HNDL = '4'.
WHEN 'COTYP_DESC'.
PS_FIELDCAT-DRDN_HNDL = '5'.
WHEN 'STATU_DESC'.
PS_FIELDCAT-DRDN_HNDL = '6'.
2）、设置下拉列表值
FORM F_SET_DROP_DOWN_LIST USING PO_ALV_GRID TYPE REF TO CL_GUI_ALV_GRID.
DATA: LT_VALUES TYPE LVC_T_DROP.
PERFORM F_SET_VALUES TABLES LT_VALUES USING 'Z_MMP_RQCAT' 1.
PERFORM F_SET_VALUES TABLES LT_VALUES USING 'Z_APP_TYPE_2' 2.
PERFORM F_SET_VALUES TABLES LT_VALUES USING 'Z_COL_SEQ_AMEND' 3.

PERFORM F_SET_VALUES TABLES LT_VALUES USING 'Z_CARR_O_TYPE' 5.
PERFORM F_SET_VALUES TABLES LT_VALUES USING 'ZWF_WFSTATUS' 6.
CALL METHOD PO_ALV_GRID->SET_DROP_DOWN_TABLE
EXPORTING
IT_DROP_DOWN = LT_VALUES.
ENDFORM. " F_SET_DROP_DOWN_LIST

DATA: LV_DOMAIN TYPE DOMNAME.
CLEAR:LS_ALV_VALUES,LV_DOMAIN,LT_VALUES[],LT_VALUES.
LV_DOMAIN = PV_DOMAIN.
CALL FUNCTION 'DD_DOMVALUES_GET' "获取DOMAIN的值列表
EXPORTING
DOMNAME = LV_DOMAIN
TEXT = GC_X

DD07V_TAB = LT_VALUES[]
EXCEPTIONS
WRONG_TEXTFLAG = 1
OTHERS = 2.
LOOP AT LT_VALUES.
LS_ALV_VALUES-HANDLE = PV_HANDEL.
LS_ALV_VALUES-VALUE = LT_VALUES-DDTEXT.
APPEND LS_ALV_VALUES TO PT_VALUES.
CLEAR: LT_VALUES,LS_ALV_VALUES.
ENDLOOP.
FREE:LT_VALUES.
ENDFORM. " F_SET_VALUES
二、以单击右边按钮的方式实现
1、效果截图如下
2、实现
有两种方式：
1）、给fieldcat里的REF_FIELD与REF_TABLE设置相应的值，即该字段所参照的哪个表的哪个字段
2）、注册F4事件
a）、调用类CL_GUI_ALV_GRID的方法注册事件

b）、注册F4事件(该事件类自己写)
