One parameter is "para1" which has values with Dataset query is select distinct col1 from test; Note: this parameter is not multivalued parameter.
Second parameter is "para2" which is cas cade and multivalued parameter with dataset query is select distinct col2 from test where col1 in (@para1)
I have executed the report by selecting "Area" in para1 and "v1" in para2. After execution i have again select "System" in para1 in first drop down. But para2 is automatically selecting "v1", Because previous execution we have selected this "v1".
But my requirement is When we select "system" in first parameter as like above, it should not select "v1" in second drop down..!
Note: I have not set any default values in any parameter.
