• What is the cause and solution for SAP error message SCMON_UI008 - All selection IDs are currently in use ?

  The SAP error message SCMON_UI008, which states "All selection IDs are currently in use," typically occurs in the context of the SAP Supply Chain Monitoring (SCMON) application. This error indicates that the system has reached the limit of available selection IDs for monitoring processes, which can happen when multiple users or processes are trying to access the same resources simultaneously.
  Cause:
  
  Exhaustion of Selection IDs: The system has a finite number of selection IDs that can be used at any given time. If all available IDs are in use, new requests for selection IDs will be denied, leading to this error.
  Long-Running Processes: If there are long-running monitoring processes that hold onto selection IDs for an extended period, they can prevent new requests from being processed.
  Concurrent Users: Multiple users accessing the monitoring tool at the same time can lead to a situation where all selection IDs are occupied.
  
  Solution:
  
  Wait and Retry: If the error is due to temporary high usage, waiting for a few moments and then retrying the operation may resolve the issue.
  Check Active Processes: Use transaction codes like SM50 or SM66 to monitor active processes and identify if there are any long-running jobs that are holding onto selection IDs. If possible, terminate or optimize these processes.
  Increase Selection ID Limit: If this issue occurs frequently, consider discussing with your SAP Basis team about increasing the limit of selection IDs if the system configuration allows it.
  Optimize Usage: Encourage users to close their sessions or monitoring views when they are done to free up selection IDs for others.
  System Configuration: Review the system configuration and settings related to SCMON to ensure they are optimized for your usage patterns.
