• What is the cause and solution for SAP error message RSMPC189 - Number of parallel load processes in source system (1-99): 10 Recommended ?

  The SAP error message RSMPC189 indicates that the number of parallel load processes configured in the source system is not optimal for the data transfer process. This message typically arises during data extraction or loading processes, particularly when using SAP Data Services or SAP BW (Business Warehouse).
  Cause:
  The error message suggests that the number of parallel load processes set in the source system is either too low or not aligned with the recommended settings for optimal performance. The recommended range is between 1 and 99, and the message indicates that the current setting is 10, which may not be sufficient for the volume of data being processed or the performance capabilities of the system.
  Solution:
  To resolve this issue, you can take the following steps:
  
  
  Adjust the Number of Parallel Load Processes:
  
  Access the configuration settings in the source system where the data is being extracted from.
  Increase the number of parallel load processes to a value that is more suitable for your data volume and system capabilities. This can typically be done in the SAP BW or Data Services configuration settings.
  
  
  
  Monitor System Performance:
  
  After adjusting the settings, monitor the system performance to ensure that it can handle the increased load without causing performance degradation.
