Check the runtime error dump in transaction or the job log in SM37 . Look for the exact line of ABAP code where the failure occurred. Identify the physical file path being accessed (e.g., /usr/sap/trans/interfaces/data.txt ). Step 2: Check OS-Level Permissions via AL11 Navigate to transaction AL11 (SAP File Directory). Locate the directory path used in your program.
Note: Increasing these values consumes more application server memory and should only be done after profiling system performance. Defensive Coding for ABAP Developers
Add MESSAGE to your OPEN DATASET command to see the actual operating system error. access denied sy-subrc 15

If a single authorization object within a user's assigned roles contains an overwhelmingly massive list of explicit values (e.g., thousands of individual Company Codes or Plant IDs instead of using ranges or asterisks), the kernel's evaluation array can experience an internal overflow during processing, defaulting the return code to 15. How to Diagnose SY-SUBRC = 15 Check the runtime error dump in transaction or
Without this, you are guessing.
Since SAP GUI 7.30, updated security rules may block SAP from interacting with certain local directories unless they are explicitly marked as "Trusted" in the SAP GUI Security Settings . Step 2: Check OS-Level Permissions via AL11 Navigate
Understanding why SY-SUBRC = 15 occurs and how to fix it requires looking at both SAP application security and host-level operating system permissions. What is SY-SUBRC?
Use the chmod and chown commands to grant the SAP administration user group read/write privileges (e.g., chmod 775 /your/directory ).
