create inquiry without material being created

Dear All,

Issue is regarding creation of inquiry, when material not being created.

Requirement is like at inquiry level customer may / may not know the material available, initially customer may not be aware of the products available but they want to buy that material.

Whereas in SAP, material has to be entered which is created in material master.

Is there any soln for the creation of inquiry / quotation (same case with Quotation too) with out material being created.

Regards,
