How To Fix AREN111 - Serial execution decreases performance

AREN111 - Overview

• Message type: E = Error

• Message class: AREN - Messages - Archiving Engine

• Message number: 111

• Message text: Serial execution decreases performance

What causes this issue?

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

Parallel processing is not active in the execution options. Serial
execution decreases performance. Because database access to the header
table is set for each package for technical reasons, the runtime for
objects without an appropriate index to the header table increases
disproportionately. Access is primarily by means of selection in the
ARCHIVE_STATUS field. For this reason, serial execution is only
suitable for small numbers of objects.

• What is the cause and solution for SAP error message AREN111 - Serial execution decreases performance ?

  The SAP error message AREN111, which states "Serial execution decreases performance," typically indicates that a process or transaction is being executed in a serial manner rather than in parallel. This can lead to performance issues, especially in environments where multiple processes could be executed concurrently to improve efficiency.
  
  Cause:
  
  Configuration Settings: The system may be configured to run certain processes serially due to specific settings or limitations.
  Resource Contention: Limited system resources (CPU, memory, etc.) may force the system to execute tasks serially.
  Process Dependencies: Some processes may have dependencies that require them to be executed in a specific order, preventing parallel execution.
  Custom Code: Custom ABAP code or enhancements may be designed in a way that does not allow for parallel processing.
  Database Locks: If database locks are held by one process, other processes may be forced to wait, leading to serial execution.
  
  
  Solution:
  
  Review Configuration: Check the configuration settings in the SAP system to ensure that
