• What is the cause and solution for SAP error message IUUC_MOD055 - Data transfer jobs should be greater than initial load jobs ?

  The SAP error message IUUC_MOD055 indicates that there is a configuration issue in the Data Transfer process within the SAP Landscape Transformation (SLT) Replication Server. Specifically, this error occurs when the number of data transfer jobs is less than the number of initial load jobs. This can lead to performance issues or replication delays.
  Cause:
  The error arises when the configuration settings for the number of data transfer jobs (which handle ongoing data changes) are set to a value that is less than the number of initial load jobs (which are responsible for loading the initial dataset). This imbalance can cause the system to struggle with processing the data efficiently, especially if there are many changes occurring while the initial load is still in progress.
  Solution:
  To resolve the IUUC_MOD055 error, you need to adjust the configuration settings in the SLT system. Here are the steps to do this:
  
  
  Access the SLT Configuration:
  
  Go to the SLT configuration transaction (usually LTRC).
  
  
  
  Check Current Settings:
  
  In the configuration settings, check the number of initial load jobs and data transfer jobs. You can find these settings under the "Configuration" tab.
  
  
  
  Adjust the Number of Data Transfer Jobs:
  
  Increase the number of data transfer jobs to be greater than the number of initial load jobs. This can typically be done in the "Settings" or "Job Parameters" section of the SLT configuration.
  
  
  
  Save the Configuration:
  
  After making the necessary adjustments, save the configuration.
  
  
  
  Restart the Replication:
  
  It may be necessary to restart the replication process for the changes to take effect.
  
  
  
  Related Information:
  
  Monitoring Jobs: After making changes, monitor the jobs in the SLT system to ensure that they are running as expected and that there are no further errors.
  Performance Tuning: Depending on the volume of data and the performance of your system, you may need to further tune the job parameters to optimize performance.
  Documentation: Refer to the official SAP documentation for SLT for more detailed information on job configuration and performance tuning.
  SAP Notes: Check for any relevant SAP Notes that may provide additional insights or updates related to this error message.
  
  By ensuring that the number of data transfer jobs exceeds the number of initial load jobs, you can effectively resolve the IUUC_MOD055 error and improve the efficiency of your data replication process.
