create report from moac (3 operating unit)

we create 3 operating unit under on ledger and one legal entity.

for example in payable if i want to create report for supplier balance

for each operating unit i can use

begin

mo_global.set_policy_context('S',&org_id);

end;

but if we create a responsibility can access 2 operating units.

or we create a responsibility can access 3 operating units.

what is the solution ?
