選擇螢幕動態隱藏欄位（SELECT-OPT…

選擇螢幕，比如查詢報表，有時候需要根據使用者選擇動態隱藏篩選條件
如果僅僅是灰掉不可顯示，直接screen-input = 0.就行，（1可編輯0不可編輯）
如果需要不顯示，screen-invisible = '1'.
如果使用了SELECT-OPTIONS:而且沒有設定NO-EXTENSION
後面會多出一個選擇值的按鈕來。
其實想去掉很簡單，直接debug看這個對應的名稱就行了。
一般前面lab頁籤是 %_定義欄位名稱_%_APP_%-TEXT
後面的值選擇按鈕是 '%_定義欄位名稱_%_APP_%-VALU_PUSH'
案例如下：
TABLES: bsid,vbak,vbrk,vbrp,knc1.
SELECTION-SCREEN BEGIN OF BLOCK b1 WITH FRAME TITLE
text-001.
PARAMETERS p_r RADIOBUTTON GROUP g1
USER-COMMAND select DEFAULT 'X'. "日模式
PARAMETERS p_y RADIOBUTTON GROUP g1
.
"月模式
SELECTION-SCREEN END OF BLOCK b1.
SELECTION-SCREEN BEGIN OF BLOCK b2 WITH FRAME TITLE t1 .

bsid-bukrs ,
