Problem: A generic RFC is used in multiple OData projects and at some point, some enhancement is needed on that object. The biggest issue is that ‘where used’ is not helpful because it doesn’t tell what all projects the RFC has been mapped as a data source. Any change can possibly impact one or more of them.

1. Check for table /IWBEP/I_SBD_DS (SB: DM Node Data Source) in SE16N.
2. Populate value of FM in field FUNCTION_NAME or NAME and it will list all projects in which the RFC has been called.

Apart from RFC, other data sources/types/objects can be identified which are used in the project.
