• What is the cause and solution for SAP error message PPH_MRP047 - Cannot start parallel processing, no resources found. Aborted. ?

  The SAP error message PPH_MRP047: Cannot start parallel processing, no resources found. Aborted. typically occurs in the context of Material Requirements Planning (MRP) when the system is unable to initiate parallel processing due to a lack of available resources. This can happen for several reasons, and understanding the cause is crucial for finding a solution.
  Causes:
  
  
  Insufficient Background Processing Capacity: The SAP system may not have enough background processing resources available. This can happen if the number of background work processes is limited or if they are all currently in use.
  
  
  Configuration Issues: The configuration settings for parallel processing in MRP may not be set correctly, leading to the system being unable to allocate resources.
  
  
  System Load: High system load or performance issues can prevent the system from allocating the necessary resources for parallel processing.
  
  
  User Authorizations: The user executing the MRP run may not have the necessary authorizations to start parallel processing.
  
  
  Job Scheduling Conflicts: Other jobs running in the background may be conflicting with the MRP job, leading to resource contention.
  
  
  Solutions:
  
  
  Check Background Processing Configuration:
  
  Go to transaction SM50 or SM66 to monitor the background jobs and see if there are any jobs currently running that are consuming resources.
  Ensure that the number of background work processes is sufficient for your needs. You can check this in transaction RZ10 or RZ03.
  
  
  
  Increase Background Work Processes:
  
  If you find that the number of background work processes is low, consider increasing the number of background work processes in the instance profile settings.
  
  
  
  Review System Load:
  
  Check the overall system performance and load. If the system is under heavy load, consider scheduling the MRP run during off-peak hours.
  
  
  
  Check User Authorizations:
  
  Ensure that the user executing the MRP run has the necessary authorizations to perform parallel processing.
  
  
  
  Job Scheduling:
  
  Review the job scheduling to ensure that there are no conflicts with other jobs. You can use transaction SM37 to check the status of background jobs.
  
  
  
  System Logs:
  
  Check the system logs (transaction SM21) for any additional error messages or warnings that might provide more context about the issue.
  
  
  
  SAP Notes:
  
  Search for relevant SAP Notes in the SAP Support Portal that might address this specific error or provide patches or updates.
