ABAP大虾，请问如何读取屏幕字段的值

Answer 1

用函数DYNP_VALUES_READ
举个例子。
I_USER，I_CODE是屏幕的字段名
"屏幕字段值
DATA: gt_dynpfields TYPE STANDARD TABLE OF dynpread.
"获取屏幕字段
CLEAR: gt_dynpfields,gw_dynpfields.
gw_dynpfields-fieldname = 'I_USER'.
APPEND gw_dynpfields TO gt_dynpfields.
gw_dynpfields-fieldname = 'I_CODE'.
APPEND gw_dynpfields TO gt_dynpfields.

CALL FUNCTION 'DYNP_VALUES_READ'
EXPORTING
dyname = sy-repid
dynumb = sy-dynnr
translate_to_upper = 'X'
TABLES
dynpfields = gt_dynpfields
