• What is the cause and solution for SAP error message CNV_CMIS_G018 - The sender system is a real subset of the receiver system, that means: ?

  The SAP error message CNV_CMIS_G018 indicates that there is a mismatch in the data structure between the sender and receiver systems during a data migration or conversion process. Specifically, it means that the sender system is a "real subset" of the receiver system. This typically occurs in scenarios where data is being transferred from one SAP system to another, such as during a system upgrade, data migration, or when consolidating systems.
  Cause:
  
  Data Structure Mismatch: The sender system has a subset of the data or configuration that exists in the receiver system. This can happen if the sender system has fewer modules, configurations, or data elements than the receiver system.
  Inconsistent Customizations: The sender and receiver systems may have different customizations or extensions, leading to discrepancies in the data model.
  Version Differences: If the sender and receiver systems are on different versions of SAP, there may be differences in the data structures that lead to this error.
  
  Solution:
  
  Data Mapping: Review the data structures in both systems and ensure that the data being sent from the sender system is compatible with the receiver system. You may need to adjust the data mapping to align with the receiver's structure.
  Subset Handling: If the sender system is indeed a subset, you may need to decide how to handle the missing data in the receiver system. This could involve:
  
  Adding the necessary data to the sender system.
  Modifying the migration process to accommodate the differences.
  
  
  Configuration Review: Check the configurations in both systems to ensure they are aligned. This may involve reviewing custom fields, tables, and other configurations.
  Consult Documentation: Refer to SAP documentation or notes related to the specific migration or conversion process you are undertaking. There may be specific guidelines or tools provided by SAP to handle such scenarios.
  Testing: Conduct thorough testing in a development or sandbox environment to ensure that the migration process works as expected before executing it in the production environment.
