Hiding Product in Quotation

Hello Experts,

I am using standard SAP Quotation application (ERP_IT web ui component) in my project and have the following requirement.

1) There are many products which we can add in this standard Assignment block ERP_IT component - Item_tab Table view.

2) All the products starts appearing once i add in this table view. There are few products which are not supposed to be shown on the UI's table view, but i still want to have them in my table view collection for some price calculation purpose.

So now how should i achieve this so that Products are not shown on the UI, but still remains in the collection wrapper ?

ERPADMINI is the context node i am using for table view. Please guide me with some sample code.

BR,
