Give Guest Access to Purchase Order Item on Website


Is it possible to give the Guest role permission to query the Purchase Order Item DocType?

I’m trying to setup an internal site, so Guest is not a security issue, where a Guest user can submit a Purchase Order.

I can do this but if I add the Purchase Order Item Child table the Guest user cannot use the Item Code field to search for items to add to the PO.

Is there a way to do this? The Purchase Order Item DocType cannot be modified, only customised. I cannot see an option to set Role permissions or allow a Web View.

Does anyone know if this is possible?
