  • What causes this issue?

    The system tries to reuse data transfer processes during the model gener
    ation. If there are several data transfer processes between the source
    &V1& and the target &V2& then only the first data transfer process is
    proposed for reuse.

  • What is the cause and solution for SAP error message RSOBI_MF166 - More data transfer processes exist; see long text ?

    The SAP error message RSOBI_MF166 indicates that there are more data transfer processes (DTPs) running than the system can handle at one time. This can occur in scenarios where multiple data loads are being executed simultaneously, leading to resource contention or exceeding the configured limits for DTPs.

    Cause:

    1. Exceeding DTP Limits: The system has a limit on the number of concurrent DTPs that can run. If this limit is exceeded, the error will occur.
    2. Long-running Processes: If some DTPs are taking longer than expected to complete, they can block new DTPs from starting.
    3. System Configuration: The configuration settings for the number of allowed parallel DTPs may be set too low for the current workload.

    Solution:

    1. Check Running DTPs: Use transaction codes like SM37 to monitor and check the status of currently running DTPs. Identify any long-running or stuck processes.
    2. Terminate Unnecessary DTPs: If you find DTPs that are not progressing, consider terminating them to free up resources.
    3. Adjust DTP Settings: Review and adjust the settings for the maximum number of parallel DTPs in the system. This can be done in the Data Warehousing Workbench (transaction RSA1) under the DTP settings.
    4. Optimize DTP Performance: Analyze the DTPs to see if they can be optimized for better performance, such as reducing the volume of data being processed in a single run or improving the underlying data model.
    5. Schedule DTPs: If possible, schedule DTPs to run at different times to avoid contention for resources.

    Related Information:

    • Transaction Codes:
      • RSA1: Data Warehousing Workbench
      • SM37: Job Monitoring
    • SAP Notes: Check for any relevant SAP Notes that may provide additional insights or patches related to DTP performance and limitations.
    • System Monitoring: Use tools like the SAP Solution Manager or transaction ST03N to monitor system performance and identify bottlenecks.

    By following these steps, you should be able to resolve the RSOBI_MF166 error and improve the efficiency of your data transfer processes in SAP.
