Dynamic list report on UI based on value help

Hi,

I need to build the dynamic list report on the UI using the CDS views and restful ABAP model.
The list report should be built based on the values selected on the value help parameter.

For example, I have Item1 and Item2 in the value help. And lets say each item will have their own masterdata tables.
When the user selects Item1 from the value help, it should read from the Item1 masterdata tables and display as list report and
when the user selects item2, the list should come from item2's master data tables.
And please note these masterdata tables are not DDIC tables, they are HANA tables.

Appriciate any inputs here are would be great if you could point me to any existing examples.
