2964628 - taxExchangeRate extrinsic expected to bring rate to backend Invoice from Ariba via ARBERP add-on

You use Suite Enablement add-on for Ariba integration, you receive a cXML message to post invoice in SAP ERP or S/4hana system, and in the cXML this part is filled:

<Extrinsic name="taxExchangeRate">4.5220</Extrinsic>

by this it is expected that this exchange rate would be used for that invoice's posting, not any other, but this not happens.
