Hi @ALL

 i try to do smth like this. one dynamic filter should execute the NULL values in the table.

FILTER "table". "column" = CASE WHEN <%=option1%> = 'abc' THEN NULL END;

all other filters work but i cannot return null values from the same table. I have tried this formula 

FILTER "table". "column" = CASE WHEN <%=option1%> = 'abc' THEN Filter_TO_NULL("table". "column") END;

but when i have tested, i realized that i did bring up all values but not Null values from table. Does anyone have an idea?
