How to setup Master Inventory Organization without implementing Inventory module.

Hi,

We have GL,AP,AR and CE modules in 11i Instance,having 30 Operating units(one of which is Parent OU of 29 Operating Units) &One L.E.

We have to define one master Inv org(that should be Parent OU of 29 Operating Units) with providing only account Informatio and ,which should be selected in Inventory Organization under Supplier TAB in "Financial Options" of Payables Module.

I defined Parent Operating Unit and given Org classification as "Operating Unit" and also as Inventory Organization and given accountig information only.

But this defined Inventory Organization is not appearing under :"Suppliers"Tab in Financial Options of the Payables Module hence stoping the defining Financial Options of the Payables being Mandatory Field.
