SAP Cloud Integration: HTTP vs. OData Receiver Adapter

"However, in some specific cases, a non-XML message body is inevitable. This is for example the case if you want to post an attachment using the "AttachmentContentSet" entity of the "API_CV_ATTACHMENT_SRV" service, which requires the payload to be a binary string. Attempting to send an XML body will lead to the following error: "com.sap.gateway.core.ip.component.odata.exception.OsciException: Bad Request : 400 : HTTP/1.1". In this case, the HTTP adapter provides the necessary flexibility regarding content-types."
