I have small doubt related to procurement type (Third party order and third party request for WBS element).
With item category N , we have an option to create "Third party order". I understand the use of this particular procurement type(material gets delivered by vendor either to another vendor or customer site hence get consumed directly) .
With item category L also we can create "Third party request for WBSE". When we do the GRN , material comes in the inventory. Just want to understand that in which scenario do we use this particular procurement type. Why SAP has given the option to create "third party req. for WBSE " for item category L??
