  The SAP error message CNV_PE_UI080 indicates that there is an existing code implementation that will be irretrievably deleted during a certain operation, typically related to a data migration or conversion process. This message is often encountered in the context of SAP's Conversion and Migration tools, particularly when using the SAP S/4HANA Migration Cockpit or similar tools.
  Cause:
  The error usually arises when:
  
  Code Overwrite: The system is attempting to overwrite or delete existing custom code or enhancements that are not compatible with the new system or version.
  Data Migration: During a data migration process, the system identifies that certain custom implementations will be lost if the migration is executed.
  Incompatibility: The existing code may not be compatible with the new data model or structure in the target system.
  
  Solution:
  To resolve this error, consider the following steps:
  
  
  Backup Existing Code: Before proceeding with any migration or conversion, ensure that you have a complete backup of the existing code implementations. This can be done by exporting the code or documenting it thoroughly.
  
  
  Review Custom Code: Analyze the existing code to determine its relevance and necessity. Identify if the code can be adapted to work with the new system or if it can be replaced with standard functionality.
  
  
  Consult Documentation: Refer to SAP's documentation regarding the migration or conversion process. There may be specific guidelines on how to handle custom code during the transition.
  
  
  Use SAP Tools: Utilize SAP tools such as the ABAP Test Cockpit (ATC) or the SAP Code Inspector to analyze the custom code for compatibility issues.
  
  
  Engage SAP Support: If you are unsure about the implications of the deletion or how to proceed, consider reaching out to SAP Support for guidance.
  
  
  Test in a Sandbox Environment: Before executing the migration in the production environment, test the process in a sandbox or development environment to see how the existing code is affected.
  
  
  Plan for Code Adaptation: If the existing code is essential, plan for its adaptation or re-implementation in the new system. This may involve rewriting parts of the code to align with the new data structures.
  
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional context.
  Migration Cockpit: Familiarize yourself with the SAP S/4HANA Migration Cockpit and its functionalities, as it may provide options for handling custom code during migration.
  Custom Code Management: Consider implementing a custom code management strategy to handle future migrations or upgrades more smoothly.
