  The SAP error message WL326, which states "End of dynamic fork," typically occurs in the context of SAP's Workload Management (WLM) or when dealing with dynamic parallel processing in ABAP programs. This error indicates that the system has encountered an issue with the dynamic forking of processes, which is often related to resource management or configuration settings.

  Resource Limitations: The system may be running out of resources (e.g., memory, CPU) to handle the dynamic fork requests.
  Configuration Issues: Incorrect settings in the SAP system configuration related to parallel processing or workload management can lead to this error.
  Program Logic Errors: There may be issues in the ABAP code that lead to improper handling of dynamic forks.
  System Load: High system load or contention for resources can also trigger this error.
