How to enable "save Query" and "Organise Queries" in SAP C4C PDI ..??

Hi experts,

I'm not able to find a way to enable these two buttons in find forms (AKA Advanced search of OWL).

As we can see, there are 4 buttons in PDI, "Go", "Reset", "save Query" and "Organise Queries", but only "Go" and "Reset" buttons are visible in browser output.

I need "save Query" and "Organise Queries" functionalities in custom BO, as seen in Opportunity .

Here is what OWL looks like in UI designer :

Below is screenshot of same OWL screen in browser (observe that two buttons missing)

Below are the screenshot of required functionality ("Opportunity" is taken as reference)

How to add "save Query" and "Organise Queries" in custom BO ..??

Help me.

Regards,
R.Ganesh.
