• What is the cause and solution for SAP error message IUUC_MAIN105 - Select at least one Table Class ?

  The SAP error message IUUC_MAIN105, which states "Select at least one Table Class," typically occurs in the context of SAP Landscape Transformation (SLT) or Data Replication processes. This error indicates that the user has not selected any table classes when trying to configure or execute a data replication task.
  Cause:
  The error is caused by the absence of a selected table class in the configuration settings. Table classes in SLT define the types of tables that can be replicated, such as:
  
  Transactional Tables: These are tables that contain transactional data.
  Master Data Tables: These tables contain master data, such as customer or vendor information.
  Custom Tables: User-defined tables that may need to be replicated.
  
  If no table class is selected, the system cannot proceed with the replication process, leading to this error message.
  Solution:
  To resolve the IUUC_MAIN105 error, follow these steps:
  
  
  Access the Configuration: Go to the SLT configuration transaction (usually transaction code LTRC or LTRS).
  
  
  Select Table Classes:
  
  Navigate to the relevant configuration settings where you can define the table classes.
  Ensure that at least one table class is selected. You may need to check the options available and select the appropriate classes based on your replication needs.
  
  
  
  Save the Configuration: After selecting the required table classes, save your changes.
  
  
  Retry the Operation: Once the configuration is updated, retry the operation that previously resulted in the error.
  
  
  Related Information:
  
  Documentation: Refer to the official SAP documentation for SLT to understand the different table classes and their implications for data replication.
  Transaction Codes: Familiarize yourself with relevant transaction codes such as LTRC (SLT Configuration) and LTRS (SLT Replication Server) for managing your SLT settings.
  SAP Notes: Check for any SAP Notes related to IUUC_MAIN105 for additional troubleshooting steps or updates that may address this issue.
  User Roles and Authorizations: Ensure that the user executing the operation has the necessary authorizations to modify SLT configurations.
