The error typically signals that the SAP GUI or the underlying OS has blocked a file operation. SAP Community 1. OS-Level Permissions The user lacks Read/Write

In the quiet, air-conditioned hum of an SAP data center, few return codes elicit a groan as heavy as SY-SUBRC = 15.
While 4 means "nothing found" and 8 usually signals a logical mistake, 15 is the system’s way of shutting the door in your face. In the context of standard SAP file operations—particularly OPEN DATASET—a return code of 15 translates to a bluntness that frustrates developers and basis teams alike: "Access Denied."
Here is the deep dive into why this happens and why it is more complex than it appears.
Understanding the exact mechanism is crucial. The error is not random. It follows this logical flow:
SE16 to view table HRP1000 (Object/Position data).AUTHORITY-CHECK object (e.g., S_TABU_LCK for table access).ACTVT = 03 for Display, TABLE = HRP1000).ACTVT 03 for HRP1000.SY-SUBRC = 15 is set, and the system throws "Access denied".Understanding SY-SUBRC 15 – Access Denied / No Authorization in SAP ABAP In ABAP programming, SY-SUBRC = 15 specifically indicates
SY-SUBRC = 15 in SAP ABAPIn the world of SAP ABAP development, few things are as simultaneously common and cryptic as the system field SY-SUBRC. While many developers are comfortable checking for SY-SUBRC = 0 (success) or SY-SUBRC = 4 (warning/not found), the value 15 often brings development to a halt—accompanied by the dreaded "Access Denied" message.
For any ABAP programmer working with authorization objects, SY-SUBRC = 15 is not merely an error code; it is a clear and definitive statement from the SAP security kernel: The user lacks the required authorization to perform the requested action.
This article dissects what SY-SUBRC = 15 means, when it occurs, and how to diagnose and resolve it.
In development, an object exists in the system, but after transport to quality or production, the authorization object itself (e.g., ZCOMPANY) is missing from the target system. The AUTHORITY-CHECK will return 12 or 15 depending on configuration.
Do not let sy-subrc 15 cause a short dump (MESSAGE type X).

You will only see sy-subrc 15 in two specific scenarios:
OPEN DATASET : Attempting to read, write, or append to a file on the application server.CALL 'SYSTEM' : Attempting to run an operating system command (e.g., cp, mv, rm, or a shell script) from within ABAP.Your own ABAP program contains:
AUTHORITY-CHECK OBJECT 'Z_SALES'
ID 'VKORG' FIELD '1000'
ID 'ACTVT' FIELD '02'.
IF SY-SUBRC = 15.
MESSAGE 'Access denied to sales org 1000' TYPE 'E'.
ENDIF.
Root Cause: The user’s profile is missing Z_SALES for VKORG 1000 and ACTVT 02.
Solution:
Z_SALES. Add the specific VKORG (1000) and activity (02).SU53Immediately after the "Access Denied" screen, the user should run /nSU53. This transaction shows exactly which authorization object failed and, crucially, for which field values. If it shows No authorization object found or a blank field list, you likely have an SY-SUBRC = 15 situation.
