Hi Experts,

I am referring to this feature "Display Recoverable Tax Amount for Requisitions" in 25B: https://docs.oracle.com/en/cloud/saas/readiness/scm/25b/ssproc25b/25B-ssproc-wn-f35893.htm

May I ask where to learn whether our implementation is configured with recoverable tax or even the nonrecoverable tax?

Is it a configuration made in Legal Entity / Business Unit / Item / PO Category level?

Which task function is it?

Please kindly advise. Thank you very much.
