SAP Error Message - Details

• Message type: E = Error

• Message class: EG - IS-U device management

• Message number: 675

• Message text: No resources available for parellel processing

How to fix this error?

Ensure that a sufficient number of free dialog processes are available.
To do this contact your system administrator
Restart the function

Procedure for System Administrators

Parallel processing requires sufficient free dialog processes to be
available. If there are too few dialog processes or if the number of
available dialog processes is lower than the sum of the batch and
update processes, then you can not use parallel processing.
You may have to create a new operation mode and activate it in order to
execute periodic replacement.

• What is the cause and solution for SAP error message EG675 - No resources available for parellel processing ?

  The SAP error message EG675 ("No resources available for parallel processing") typically occurs when the system is unable to allocate the necessary resources to execute a task in parallel. This can happen in various scenarios, such as during batch processing, background jobs, or when executing certain transactions that require parallel processing capabilities.
  Causes:
  
  Insufficient Background Processing Capacity: The system may not have enough background work processes available to handle the parallel requests.
  Configuration Issues: The configuration settings for parallel processing may not be set correctly, leading to resource allocation problems.
  System Load: High system load or resource contention can prevent the allocation of resources for parallel processing.
  Job Scheduling Conflicts: If multiple jobs are scheduled to run at the same time, it can lead to resource exhaustion.
  Memory Limitations: The system may be running low on memory, which can affect its ability to allocate resources for parallel tasks.
  
  Solutions:
  
  
  Check Background Process Configuration:
  
  Go to transaction RZ10 or RZ12 to check the profile parameters related to background processing (e.g., rdisp/wp_no_btc for the number of background work processes).
  Increase the number of background work processes if necessary.
  
  
  
  Monitor System Load:
  
  Use transaction SM50 or SM66 to monitor the current workload and see if there are any long-running processes that are consuming resources.
  Identify and terminate any unnecessary or stuck processes.
  
  
  
  Adjust Job Scheduling:
  
  Review the job scheduling in transaction SM37 to see if there are any overlapping jobs that could be rescheduled to reduce contention.
  Stagger the execution of jobs that require significant resources.
  
  
  
  Check Memory Settings:
  
  Ensure that the system has adequate memory allocated. You can check memory settings in transaction RZ10.
  Consider increasing the memory allocation if the system is consistently running low.
  
  
  
  Review Parallel Processing Settings:
  
  Check the settings for parallel processing in the specific transaction or program you are running. Some programs have their own settings for how many parallel processes they can use.
  
  
  
  System Performance Tuning:
  
  Perform general system performance tuning to optimize resource usage. This may include database tuning, adjusting kernel parameters, or optimizing ABAP code.
