There is a standard scenario to use for this webservice.
This scenario can be activated by enabling the scoping option,
Manufacturing, Warehousing, and Logistics --> Inventory Management --> Inventory Postings --> Do you want to allow third-party software to read confirmation data from warehousing and production?
After enabling the above question, try to create a new communication arrangement from Application and User Management --> Communication Arrangements. You will now see a new communication scenario in the available list with name SCM Confirmation Query Services which is a pack of several services and QueryProductionLotISIInis one among them. Enjoy.
