• What is the cause and solution for SAP error message IUUC_MAIN091 - No parallelization data available for table &1 ?

  The SAP error message IUUC_MAIN091 indicates that there is no parallelization data available for a specific table during the execution of a data transfer or replication process, typically in the context of SAP Landscape Transformation (SLT) or SAP Data Services.
  Cause:
  
  
  Missing Parallelization Data: The error usually occurs when the system is unable to find the necessary parallelization data for the specified table. This can happen if:
  
  The table is not configured for parallel processing.
  The table does not have a primary key or unique index that can be used for parallelization.
  The configuration settings for the table in the SLT or data replication setup are incomplete or incorrect.
  
  
  
  Table Configuration Issues: If the table is newly created or modified, the parallelization settings may not have been updated or activated.
  
  
  Replication Settings: The replication settings for the table may not be properly defined, leading to the absence of parallelization data.
  
  
  Solution:
  
  
  Check Table Configuration:
  
  Ensure that the table has a primary key or a unique index defined. This is essential for parallel processing.
  Verify that the table is correctly configured in the SLT configuration. You can do this by checking the SLT configuration settings in transaction code LTRC.
  
  
  
  Update Parallelization Settings:
  
  If the table is not set up for parallel processing, you may need to enable it. This can typically be done in the SLT configuration settings.
  Use transaction code LTRC to check the configuration and make necessary adjustments.
  
  
  
  Reinitialize Replication:
  
  If changes were made to the table or its configuration, you may need to reinitialize the replication for that table. This can be done through the SLT configuration interface.
  
  
  
  Check for Errors in Logs:
  
  Review the SLT logs for any additional error messages or warnings that may provide more context about the issue. You can access logs through transaction LTRC or SLT monitoring tools.
