What happens when an authorization check fails?

When an authorization check fails in SAP, the system sets the field SY-SUBRC to a value other than zero. SY-SUBRC is a system variable that provides the return code from the last operation, and a return code other than zero indicates that the operation did not complete successfully, which in this case signifies that the authorization check has failed. This behavior is standard across many different operations in SAP, providing a consistent mechanism for checking the outcomes of various processes, including authorization checks.

While raising exceptions or messages may occur, the critical indication of a failed authorization check is primarily reflected in the SY-SUBRC field. Therefore, the setting of SY-SUBRC accurately reflects the failure of the authorization check and serves as a vital part of how developers can handle such scenarios in their code.
