How To Fix W_MD003 - No new tasks could be started due to lack of resources

SAP Error Message - Details

• Message type: E = Error

• Message class: W_MD - Message Class for Merchandise Distribution

• Message number: 003

• Message text: No new tasks could be started due to lack of resources

What causes this issue?

No (additional) tasks could be started within parallel processing as no
resources are available.

System Response

After a resource problem has been recorded by the parallel processing
environment, the system tries to run the process again after waiting
ten seconds. The system tries to do this ten times. If resources are
still not available after the ten attempts, processing is cancelled.
Processing was cancelled in step: &V1&.

How to fix this error?

Depending on when cancellation took place, you can repeat processing
after correcting the problem.

Procedure for System Administrators

Identify and resolve the resource problem.

• What is the cause and solution for SAP error message W_MD003 - No new tasks could be started due to lack of resources ?

  The SAP error message W_MD003 ("No new tasks could be started due to lack of resources") typically indicates that the system is unable to allocate the necessary resources to start new tasks in the background processing environment. This can occur in various scenarios, particularly in the context of background jobs, batch processing, or when the system is under heavy load.
  Causes:
  
  
  Resource Limitations: The system may have reached its limit for background processing tasks, which can be due to:
  
  Maximum number of background jobs configured in the system.
  Insufficient memory or CPU resources available for processing.
  High system load or contention for resources.
  
  
  
  Configuration Settings: The configuration settings for background processing may not be optimized, leading to resource constraints.
  
  
  Job Scheduling Conflicts: There may be too many jobs scheduled to run at the same time, causing a bottleneck.
  
  
  Database Locks: If there are locks on database tables that are required for the tasks, it can prevent new tasks from starting.
  
  
  System Parameters: Certain system parameters related to background processing may be set too low.
  
  
  Solutions:
  
  
  Check Background Job Configuration:
  
  Review the configuration settings for background jobs in transaction SM37 (Job Monitoring) and SM36 (Define Background Job).
  Ensure that the maximum number of background jobs is set appropriately.
  
  
  
  Monitor System Resources:
  
  Use transaction SM50 (Process Overview) to monitor the current processes and check for any that are consuming excessive resources.
  Check system performance metrics to identify any bottlenecks in CPU, memory, or I/O.
  
  
  
  Adjust System Parameters:
  
  Review and adjust relevant parameters in transaction RZ10 (Profile Parameters) that control background processing, such as rdisp/wp_no_btc (number of background work processes).
  
  
  
  Optimize Job Scheduling:
  
  Stagger the scheduling of background jobs to reduce contention for resources.
  Review and possibly reschedule jobs that are not time-sensitive.
  
  
  
  Check for Locks:
  
  Use transaction SM12 (Display and Delete Locks) to check for any locks that may be preventing tasks from starting.
  Resolve any unnecessary locks.
  
  
  
  Increase Hardware Resources:
  
  If the system is consistently under heavy load, consider upgrading hardware resources (CPU, memory) or optimizing the database.
  
  
  
  Review System Logs:
  
  Check the system logs (transaction SM21) for any additional error messages or warnings that may provide more context about the resource issues.
  
  
  
  Related Information:
  
  SAP Notes: Check SAP Notes for any known issues or patches related to background processing and resource management.
  Performance Tuning: Consider engaging in performance tuning activities to optimize the overall system performance.
  SAP Community: Engage with the SAP Community forums for insights and solutions from other users who may have encountered similar issues.
  
  By following these steps, you should be able to identify the root cause of the W_MD003 error and implement a solution to resolve it.
