Positive lists for RFC callback, SAP security note 1686632

Description

This security note has been updated. For more detailed information, see security note 2102941.

When you use a synchronous RFC in ABAP, you can, from the context of the remote (called) function module, use the RFC destination "BACK" to execute remote-enabled modules in the context of the RFC caller if the RFC caller has the necessary RFC authorizations and the callback is not prohibited by the previous call of the function module RFC_CALLBACK_REJECTED (see SAP Note 1515925).
