User-Defined Function (UDF) in Message Mapping
An RFC Lookup is a mechanism in SAP integration scenarios that allows an integration flow to call a remote-enabled function module in an SAP system via the Remote Function Call (RFC) protocol. Developers use it to retrieve or exchange data with backend SAP systems at runtime during message processing. In the context of migration, developers moving from SAP Process Orchestration to Cloud Integration must re-implement RFC Lookups using the appropriate adapters and scripting capabilities available on the cloud platform.
