@Avinash Krishnaram-Oracle No, the parameters are working fine. The problem is pinning the top filters in the Present mode. It's the exact same issue Marcelo Finkielsztein have explained above. As he explained, "Pin-to-all-canvases" would be an amazing feature to have on the 'Present' mode, but it is not currently available (at least in OAS 7.0). Users need to filter again and again for each canvas which is a very painful process for the users. I have attached the screenshot below which shows that I am unable to pin the 'Employee Initials' filter for canvas 1 & canvas 2. In the example below, when I changed the 'Employee Initials' value on canvas 1 to 'A.A.J' & 'A.B.', the 'Employee Initials' value on canvas 2 should automatically be set to 'A.A.J' & 'A.B.' as well. However you can see the 'Employee Initals' filter on the canvas 2 is still set to 'All'.

Note:- The filter pinning works well in the 'Visualize' Mode. This problem is only specific to 'Present' Mode.
