Based on the error message, it appears that the issue is originating from an SAP function module and seems to be related to a timeout. Although I am not familiar with SAP, my research indicates that this is likely an SAP-specific issue that needs to be investigated by SAP experts. I recommend reaching out to the SAP community forum for assistance with this matter.
If the SAP experts identify anything specific to Azure Data Factory, please let us know, and we will thoroughly investigate it.
For reference, here is a similar forum thread from the SAP community: "RODPS_REPL_ODP_FETCH error when loading from SLT to Azure via SAP CDC Connector." Please review this thread to see if it provides any insights from the SAP side.
