PO Release Strategy for a single Plant

Dear Friends,

I have created a new release strategy to trigger multiple plants

Release Strategy is triggering in case of PO is having more than one single Plants but not in case of a single plant in one item or multiple items for the same plants.

I know that PO release strategy is at header level so I have not entered plant in CL24N.My purpose is solved in case of aPO is having more thatnn one plant but still i need to get the Release Strategy to trigger in case of any single plant or more than one time by using a single plant in PO.

Has anybody done this? Could you please suggest any logic to be developed if available

Thanks
