SAP S/4HANA Cloud Public Edition All versions

Transfer a payload with a different header and item currency via Odata API API_SUPPLIERINVOICE_PROCESS_SRV

The critical currency is the header document currency.
The API will always check that the item currency is maintained in the payload and that the item currency matches the document currency.

** Note: In some localization scenarios a special amount field is present, these fields are not supported by the API.

Make sure the "DocumentCurrency" in the item level of the payload is the same as header "DocumentCurrency".
