Ad hoc Query - Add table to an existing Infoset

Hi,

I have an Infoset created based on PNP database table. Now I wanted to add certain fields from a table (not from logical database table) to same Infoset. Can I add the table to the existing Infoset? If yes could please guide me how to do it.

From one thread I found out using Extras tab, in change Infoset screen we can add table. But not able to proceed further.

I will be grateful for your help.

Thank you.
