How to prevent over-receipting -PO

Hi,

We are seeing a situation in Oracle Fusion Cloud Procurement where receiving transactions are allowed to significantly exceed the PO amount, and Manage Receiving Parameters task appear disabled. In one case, the PO was approximately USD 80k, the ordered/invoiced amount was about USD 23k, but the received amount was over USD 557k, with no warning or approval triggered. Are receiving tolerances supported for amount-based PO lines, and if not, what is Oracle’s recommended way to prevent or control excessive over-receipting when receipt amounts exceed the PO value? Thanks in adavance.

Regards,

Nikhita.
