"Restarting the SAP instance fixes SY-SUBRC 15." Fact: Absolutely not. This is a role-based permission error. Restarting the system will not re-generate a user’s missing profile. Conclusion The SY-SUBRC 15 – Access Denied error is not a mysterious system glitch; it is the SAP security model doing its job. It is a deliberate blockade to protect sensitive data and critical functions. OPEN DATASET failed; SY-SUBRC = 15 Root Cause:

RFC callback denied. Authorization object S_RFC failed. SY-SUBRC 15 Root Cause: The RFC user (often RFCUSER or ALEREMOTE ) is missing object S_RFC with fields RFC_TYPE = FUGR (Function Group) and RFC_NAME = SYST (for system calls) or the specific function group. MESSAGE 'Access denied to sales org 1000' TYPE 'E'

"If I use RFC, SY-SUBRC 15 on the source system means the target system is down." Fact: No. SY-SUBRC 15 on the source system means the authorization check before sending the RFC failed. The target system never received the call.

For those uninitiated, SY-SUBRC (System Sub-Return Code) is the standard variable in ABAP programming that indicates the success or failure of an operation. While a value of 0 signifies success, SY-SUBRC 15 specifically points to a critical authorization failure.
