最近做屏幕開發的時候，通過屏幕的POV事件動態生成Search Help時候，不能取到當面屏幕字段的值（必須要打一個回車鍵），為了解決此問題，可以通過Call 一個Function來動態取到屏幕的值，代碼如下：
?1、? 100屏幕的POV事件
????
?2、事件代碼
?????DATA:?wls_return?TYPE?ddshretval,
????????wlt_return?LIKE?TABLE?OF?wls_return.
??data:????????it_dynpfields?TYPE?STANDARD?TABLE?OF?dynpread,
????????wa_dynpfields?TYPE?dynpread.
??CLEAR?ws_t012.
??REFRESH?wt_t012.
??CLEAR?wa_dynpfields.
??CLEAR?it_dynpfields.
*解決屏幕輸入時捕捉不到值的問題
**取公司代碼屏幕字段的輸入值
??wa_dynpfields-fieldname?=?‘P_BUKRS’.
??APPEND?wa_dynpfields?TO?it_dynpfields.
??CALL?FUNCTION?‘DYNP_VALUES_READ’
????EXPORTING

????READ?TABLE?it_dynpfields?WITH?KEY?fieldname?=?‘P_BUKRS’?INTO?wa_dynpfields.
??IF?NOT?wa_dynpfields-fieldvalue?IS?INITIAL.
????P_BUKRS?=?wa_dynpfields-fieldvalue.?“得到屏幕錄入的值
??ENDIF.?
?IF?p_zz001?NE?space.
????CONCATENATE?‘%’?p_zz001?INTO?p_zz001.
??select?zz001?zbanktxt
????into?corresponding?fields?of?table?wt_t012
