SAP S/4HANA Error 1802: Shared Memory Permission Denied
Description
This error indicates that a program or process attempted to release or detach from a shared memory segment, but the current user executing the process does not have the necessary permissions because they are not the original creator of that segment. This typically occurs in scenarios involving system administration tasks, background jobs, or custom applications interacting with shared memory resources.
Error Message
ERR_SHM_DROP_NO_PERMISSION
Known Causes
4 known causesProcess Run by Wrong User
A program or script attempting to manage shared memory was executed by a user ID different from the one that initially created the shared memory segment.
Automated Job User Mismatch
A scheduled background job or automated task is configured to run under a user account that lacks the creator privileges for the specific shared memory segment it tries to drop.
Application Logic Flaw
Custom or third-party application code attempts to interact with shared memory without properly verifying the user context or assuming creator privileges are always present.
System Security Restrictions
Strict operating system or SAP security policies prevent users from modifying shared memory segments not owned by their effective user ID, even if they have other elevated privileges.
