sy-subrc 15 can be a symptom of resource exhaustion, not just permissions. Part 6: Preventive Coding – Avoiding sy-subrc 15 Altogether The best way to handle sy-subrc 15 is to write code that anticipates it gracefully. Pattern: The Safe File Writer Do not let sy-subrc 15 cause a short dump (MESSAGE type X).

The developer checks OPEN DATASET . No change. The admin checks ls -ld /tmp/export .

# On OS level: chmod +x /usr/sap/trans/scripts/my_script.sh chown a4hadm:sapsys /usr/sap/trans/scripts/my_script.sh The Incident: A batch job ran every night to write CSV files to /tmp/export/ . It worked for two years. Suddenly, every run fails with sy-subrc 15 . access denied sy-subrc 15

DATA: lv_filename TYPE string, lv_rc TYPE i, lv_os_error TYPE string. lv_filename = '/usr/sap/export/output.txt'.

For standard OpenSQL operations, 4 might mean "no rows found." However, for low-level system operations—specifically and External command execution (CALL 'SYSTEM') —the code 15 takes on a distinct personality. The Official Definition According to SAP documentation, when using OPEN DATASET or CALL 'SYSTEM' , sy-subrc 15 translates to: "Access denied. No authorization for this access." sy-subrc 15 can be a symptom of resource

While a generic "Access Denied" pop-up might send a junior developer scrambling to check basic login credentials, a seasoned SAP professional knows that the devil is in the details—specifically, the system variable .

# Change ownership to the SAP admin user (e.g., a4hadm) chown -R a4hadm:sapsys /path/to/directory find /path/to/directory -type d -exec chmod 755 {} ; find /path/to/directory -type f -exec chmod 644 {} ; The developer checks OPEN DATASET

Over time, the job generated 50,000+ files. The OS hit a limit on directory inodes. The directory became full of entries. The OS denied creation of new files because the directory's link count was maxed out, returning EACCES (Access Denied).
