Runtime error occurs when using DropdownByKey
I run into a runtime error when I use the DropDowByKey with fixed value set: the value seletedKey = "001" in DropDownByKey "DDBK_APP_STATE" does not exist in the value list and is not initial either. But I have already added the value pair of the selectedKey using
NAME = 'APP_STATE'
VALUE_SET = LT_VALUESET )." and I can select it from view. But when I use the attribute bound to the dropdownbykey in select statement as where condition and bind result into table. Before the screen reflash , the error occurs.
