• What is the cause and solution for SAP error message CNV_OR_PE001 - ABAP OO class or interface &1 not found in &2 (system ID=&3) ?

  The SAP error message CNV_OR_PE001 indicates that an ABAP Object-Oriented (OO) class or interface specified in the system is not found. This error typically occurs during data migration or conversion processes, particularly when using SAP's Conversion Tools or during the execution of programs that rely on specific classes or interfaces.
  Cause:
  
  
  Missing Class/Interface: The specified class or interface does not exist in the target system. This could be due to:
  
  The class/interface not being transported to the target system.
  The class/interface being deleted or not activated.
  The class/interface being part of a package that is not available in the target system.
  
  
  
  Incorrect Naming: There might be a typo or incorrect naming in the reference to the class/interface.
  
  
  Version Mismatch: The source and target systems may be on different versions of SAP, leading to discrepancies in available classes/interfaces.
  
  
  Transport Issues: If the class/interface was supposed to be transported from another system, there may have been issues with the transport request.
  
  
  Solution:
  
  
  Check Existence: Verify if the class or interface exists in the target system:
  
  Use transaction SE80 or SE24 to search for the class/interface by name.
  If it does not exist, check if it was supposed to be transported.
  
  
  
  Transport the Missing Object: If the class/interface is missing, transport it from the source system where it exists. Ensure that the transport request is correctly released and imported into the target system.
  
  
  Activate the Class/Interface: If the class/interface exists but is not activated, activate it using transaction SE80 or SE24.
  
  
  Check Naming: Double-check the spelling and naming conventions used in the code or configuration that references the class/interface.
  
  
  Review Version Compatibility: Ensure that the source and target systems are compatible in terms of SAP version and that the necessary components are installed.
  
  
  Consult Documentation: If the class/interface is part of a specific SAP application or module, consult the relevant documentation or SAP Notes for any prerequisites or dependencies.
  
  
  Related Information:
  
  Transaction Codes: SE80 (Object Navigator), SE24 (Class Builder), SE37 (Function Module), SE11 (Data Dictionary).
  SAP Notes: Search for relevant SAP Notes that might address known issues with specific classes/interfaces or migration tools.
  Debugging: If you have access to the ABAP code, you can debug the program to identify where the error is being triggered and gather more context about the missing class/interface.
  
  If the issue persists after following these steps, consider reaching out to SAP support or your internal SAP Basis team for further assistance.
