Unable to add material items in Supervisor Workbench due to unused field validations

Summary:

This page needs an items search, I'd hate to have to maintain an excel sheet for people to find part numbers.

When adding a required item the page tries to validate a field which is not in use or for which we even have values populated for. Why doesn't this validation match what is validated in Manage Work Orders or Dispatch list.

Content (please ensure you mask any confidential information):

We don't currently use Repair Transaction Code, yet it is blocking me from adding materials.
