Funktionsbaustein DYNP VALUES UPDATE

Mit dem Funktionsbaustein DYNP_VALUES_UPDATE kann man mehrere Werte auf einem Dynpro ändern, ohne dass der PBO durchlaufen werden muss.

Hier soll beim ersten Parameter PDF (bzw. P_PDF1) möglich sein mehrere Dateien auszuwählen, die dann in maximal 10 Parameterfelder zurückgeschrieben werden.
