Invalid IDR invoice got generated by the system which ideally should not.

Hi Team,

IDR has read the payment receipt of the supplier **** and created invalid invoice against YYY in system. Someone from supplier sent the Payment receipt on the IDR email and system picked it up and created the invoice, This supplier (****) is not available in the system and is specific to our 1 business unit for which we have not configured AP subledger hence invoice got generated for another supplier as Invalid.

This is not even an invoice but a payment receipt, so should not have been loaded by IDR to any entity BU and not picking a random supplier.
