Single receipt against multiple invoices from different customers within one operating unit OU.

Hi,

We've one requirement to do single AR Receipt for multiple customer invoices within same OU (operating unit). Currently we are unable to do this activity due to one restriction over Receipt header form that Apply function is not getting enabled unless user put customer reference or transaction / invoice reference into tab portion of Receipt Header form.

We've got some alternative solutions like customer relationship definition about this type of requirement but that doesn't seem feasible or fulfill our requirement since our client's customers volume is bit high and it seems not possible to define relation for each customer to each other.
