1. Go to the Administrator work center.
2. Go to the General Settings work view.
3. Go to Webservice message monitoring.
4. Check the failed message with service interface "MaterialReplicationInitiatedByExternalIn".
5. View Payload to find the data sent to C4C:

         </QuantityCharacteristic>
                <QuantityCharacteristic actionCode="04">
                    <Quantity unitCode="XXX">1</Quantity>
                    <CharacteristicQuantityTypeCode>XXX</CharacteristicQuantityTypeCode>
                    <CharacteristicQuantity xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:nil="true"/>
          </QuantityCharacteristic>

Error is due to empty CharacteristicQuantity sent under QuantityCharacteristic nodes to C4C.
SAP has updated the message mapping to handle such information and drop those nodes without reaching C4C.

 Therefore, please ensure you are using the latest message mapping in case of PI or iflows in case of CPI
