Access Denied Sy-subrc 15 ⚡ Trusted Source

The most common reason for SY-SUBRC = 15 isn't that the file is missing (that would be code 8), nor that the path is wrong. It is almost always a conflict of identity.

When an ABAP program attempts to read or write a file on the application server using OPEN DATASET, it is not doing so as you (the human user logged into the GUI). It is doing so as the Operating System User that owns the SAP Work Process (typically sidadm on UNIX/Linux systems).

This creates a classic "Great Impersonation" scenario: access denied sy-subrc 15

The best way to handle sy-subrc 15 is to write code that anticipates it gracefully.

This is the most frequent occurrence. A functional user tries to view a custom table ZEMPLOYEE_DETAILS or an HR table PA0001. The most common reason for SY-SUBRC = 15

Error Example:

Access denied for table ZEMPLOYEE_DETAILS. (SY-SUBRC 15) Access denied for table ZEMPLOYEE_DETAILS

Root Cause: The authorization object S_TABU_LCK (Table Locking/Tracking) is triggered. The user lacks authorization for ACTVT (Activity) = 03 (Display) or 02 (Change).

Solution:

Do not just check for SY-SUBRC <> 0. Differentiate:

AUTHORITY-CHECK OBJECT 'S_CARRID'.
IF SY-SUBRC = 0.
  " Authorized
ELSEIF SY-SUBRC = 4.
  MESSAGE 'Partial authorization (specific value missing)' TYPE 'W'.
ELSEIF SY-SUBRC = 15.
  MESSAGE 'No authorization object assigned at all' TYPE 'E'.
ELSE.
  MESSAGE 'Other error' TYPE 'E'.
ENDIF.

The biggest hurdle with sy-subrc 15 is that ABAP is lazy with error details. sy-subrc gives you the number, but not the reason. Here is a systematic approach to getting the truth.
