Supported SAP entities
The SAP writeback service connects to SAP standard delivered OData V2.0 endpoints available in SAP S/4HANA. It supports the following SAP entities: Attachment writeback requests include a file reference on each request item. Choose the reference type based on how the file is stored in CDF.
In the API,
type: "cdf_classic_file" is synonymous with an asset-centric (legacy) file. Use asset-centric file references in asset-centric and hybrid projects. Data modeling projects must use cdm_file with a CogniteFile instance.
Don’t set both
fileId and fileReference on the same request item. The request fails with HTTP 422.fileReference fields. To send an attachment writeback request, see Set up the SAP writeback service. For the full request schema, see Writeback requests.
