You should create a null PL/SQL action which passes P4_LIST item as parameter (in order to alter session value, otherwise the value change is not shown when refreshing report), after that action you must refresh report region. Be aware that you must enable "Enable Partial Page refresh" under report properties, this is mandatory! Hope that helps!

The problem was that I didn't select the partial refresh of the Tabular Form, now it works.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
