  The SAP error message DMC_RT_GEN107 indicates that a specific table (denoted as &1) is excluded from the generation process due to its table class (denoted as &2). This typically occurs in the context of Data Migration Cockpit (DMC) or when working with data models in SAP systems.
  Cause:

  Configuration Settings: The configuration settings in the Data Migration Cockpit or the data model may specify that certain table classes should be excluded from processing.
  Data Model Design: The design of the data model may intentionally exclude certain tables based on business logic or data governance policies.

  Review Configuration: Check the configuration settings in the Data Migration Cockpit or the relevant data model to see if there are any exclusions set for specific table classes. Adjust the settings if necessary.

  Consult Documentation: Review SAP documentation or notes related to the Data Migration Cockpit and table classes to understand the implications of the exclusion and any recommended practices.
