• What is the cause and solution for SAP error message RSMPC188 - A maximum of 99 parallel load processes are permitted; reducing number ?

  The SAP error message RSMPC188 indicates that the system has reached the maximum limit of parallel load processes allowed for a particular operation, which is set to 99. This typically occurs during data loading processes, such as when using the SAP Data Transfer Workbench or during data extraction and loading in SAP BW (Business Warehouse).
  Cause:
  
  Exceeding Parallel Load Limit: The error arises when the number of parallel processes trying to load data exceeds the configured limit of 99.
  System Configuration: The system may be configured to allow a maximum of 99 parallel processes, which is a default setting in many SAP systems.
  High Volume of Data: If a large volume of data is being processed simultaneously, it can lead to this error.
  
  Solution:
  
  
  Reduce Parallel Processes: 
  
  Adjust the settings in your data loading process to reduce the number of parallel processes. This can often be done in the data loading tool or job configuration.
  If you are using a specific transaction or program, check the parameters for controlling the number of parallel processes.
  
  
  
  Batch Processing: 
  
  Instead of loading all data at once, consider breaking the data into smaller batches and loading them sequentially.
  
  
  
  System Configuration: 
  
  If you have administrative access, you can consider increasing the maximum number of parallel processes allowed in the system configuration. However, this should be done with caution, as it may impact system performance.
  This can typically be adjusted in the SAP profile parameters (e.g., rdisp/wp_no_btc for background work processes).
  
  
  
  Monitor System Performance: 
  
  Use transaction codes like SM37 (Job Monitoring) to check the status of background jobs and identify if there are any jobs that are stuck or taking too long, which may be contributing to the issue.
  
  
  
  Consult Documentation: 
  
  Review SAP documentation or notes related to the specific data loading process you are using for any additional recommendations or best practices.
  
  
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that may provide additional insights or updates regarding this error.
  Performance Tuning: Consider performance tuning of your SAP system to handle larger data loads more efficiently.
  SAP Community: Engage with the SAP Community forums for shared experiences and solutions from other users who may have encountered the same issue.
  
  By following these steps, you should be able to resolve the RSMPC188 error and successfully manage your data loading processes in SAP.
