Show results fusing drop down menu

Hi There -

I got the list of entries made in a sheet whish i want to show to the user by choosing the list from a dropdown menu / list choosing SBU & Category. Once after choosing both, he / she should be able to view the results that are matching. Also when choosed SBU by user, He/ she should view only corrsponding categories from the drop down list to choose.

The requirement can be achived by using filters, but the users are not familier with excel and would like to make simple and well organized for easy and quick reference.

Annexed here with a spread sheet list for quick reference. Appriciate all your help and thanks for viewing.

Best Regards,
Ron
