Disable Item Requirement On Sales Order and To make Sales order directly from WBS on Project

Hi Professionals Dynamics Users,

I am working on the module Project Management and Accounting and my client want to disable the Item requirement option and want to make sales order directly from the WBS. When we are creating the sales order from the Item requirement its type is ITEM REQUIREMENT but we need Type as Sales Order.

I just need to disable the tracking of item requirement and making the sales order directly when creating project WBS, Please help.
