• Message number: 168

• Message text: Utilized area of spool request queue for processing in order (in %)

What causes this issue?

If a spool server has several spool work processes, output requests
can overtake each other. In order to ensure that requests are processed
in the correct order, there are special work process-specific request
queues that each deal with one particular output device.

• What is the cause and solution for SAP error message RT168 - Utilized area of spool request queue for processing in order (in %) ?

  The SAP error message RT168 indicates that the utilized area of the spool request queue for processing is at a certain percentage, which may suggest that the spool system is nearing its capacity. This can lead to issues with printing or generating spool requests if the limit is reached.
  Cause:
  
  Spool Queue Capacity: The spool request queue has a defined capacity, and if the number of spool requests or the size of the requests exceeds this capacity, you may encounter this error.
  Configuration Settings: The configuration settings for the spool system may not be optimized for the volume of print jobs being processed.
  Long-Running Jobs: If there are long-running jobs that are holding onto spool resources, it can lead to a backlog in the spool queue.
  System Load: High system load or insufficient resources (CPU, memory) can also affect the spool processing.
  
  Solution:
  
  Monitor Spool Requests: Check the spool requests in transaction SP01. Identify any requests that are stuck or taking too long to process and consider deleting or reprocessing them.
  Increase Spool Capacity: If the spool queue is consistently reaching its limits, consider increasing the spool capacity. This can be done in the SAP system configuration (transaction SPAD).
  Optimize Spool Configuration: Review and optimize the spool configuration settings. This includes adjusting parameters such as the number of spool work processes and the maximum number of spool requests.
  Clear Old Spool Requests: Regularly clear out old or unnecessary spool requests to free up space in the spool queue.
  Check for Errors: Look for any errors in the spool processing that may indicate issues with specific print drivers or devices.
  System Performance: Ensure that the system has adequate resources (CPU, memory) to handle the load. If necessary, consider scaling up the hardware or optimizing other processes running on the system.
