Smart SAP Assistant

• What is the cause and solution for SAP error message CNV_MBT352 - Activity start was not more possible. Free BTC = 0. Max.Jobs = &1 ! ?

  The SAP error message CNV_MBT352 indicates that a certain activity could not be started because there are no available background processing units (BTC) left. The message states that the maximum number of jobs has been reached, which is denoted by Max.Jobs = &1. This typically occurs in the context of data migration or conversion processes, particularly when using the SAP Migration Tool.
  Cause:
  
  Exhausted Background Processing Capacity: The system has reached the maximum number of background jobs that can be executed simultaneously. This can happen if there are too many jobs running at the same time or if the system is configured with a low limit for background jobs.
  System Configuration: The configuration settings for background processing may be set too low, limiting the number of concurrent jobs.
  Long-Running Jobs: If there are long-running background jobs, they may occupy the available slots, preventing new jobs from starting.
  
  Solution:
  
  Check Background Jobs: Use transaction code SM37 to check the status of background jobs. Look for any jobs that are running for an extended period and consider terminating them if they are no longer needed.
  Increase Max Jobs: If you have the necessary authorizations, you can increase the maximum number of background jobs allowed in the system. This can be done in the system profile parameters:
  
  Go to transaction RZ10.
  Look for the parameter rdisp/wp_no_btc and increase its value.
  Save the changes and restart the instance for the changes to take effect.
  
  
  Optimize Job Scheduling: Review the scheduling of background jobs to ensure that they are not all running at the same time. Staggering job execution can help manage the load on the system.
  Monitor System Performance: Regularly monitor the performance of the system to ensure that it can handle the required number of background jobs without issues.
  
  Related Information:
  
  Transaction Codes:
  
  SM37: Monitor background jobs.
  RZ10: Maintain profile parameters.
  SM50: Monitor work processes.
  
  
  SAP Notes: Check for any relevant SAP Notes that may provide additional insights or solutions related to background job management and performance tuning.
  Documentation: Review SAP documentation on background processing and job scheduling for best practices.
  
  By following these steps, you should be able to resolve the CNV_MBT352 error and successfully start the required activity.
