Existing Items are not showing up in iProcurement page in newly created operating unit

The client created a new operating unit and iProcurement responsibility (assigned New Operating unit through MO: Operating unit profile). The Items (existing, not newly created) are not appearing upon search in the newly created iProcurement responsibility.

There are a bunch of oracle notes available on the oracle support site, however, none of them helped.

Anyone faced this kind of issue when the newly created OU was associated with iProc responsibility. Pls help.

Thanks, Jay
