• What is the cause and solution for SAP error message CNV_PE_CHECK081 - No interface mapping exists for transformation rule &2 of rule &1 ?

  The SAP error message CNV_PE_CHECK081 indicates that there is no interface mapping available for a specific transformation rule in the context of a data migration or conversion process. This error typically arises during the execution of a data migration project, particularly when using the SAP Landscape Transformation (SLT) or SAP Data Services.
  Cause:
  The error can occur due to several reasons:
  
  Missing Interface Mapping: The transformation rule specified in the error message does not have a corresponding interface mapping defined in the system.
  Incorrect Configuration: The configuration for the data migration might be incomplete or incorrect, leading to the absence of necessary mappings.
  Changes in Transformation Rules: If transformation rules have been modified or deleted after the initial setup, it may lead to inconsistencies.
  Transport Issues: If the relevant transport requests containing the mappings were not imported correctly into the target system, this error may occur.
  
  Solution:
  To resolve the error, you can take the following steps:
  
  
  Check Interface Mappings:
  
  Go to the relevant transaction (e.g., LTMC, LTMOM, or LTMOM for migration objects) and verify if the interface mapping for the specified transformation rule exists.
  If it does not exist, you may need to create it or restore it from a backup.
  
  
  
  Review Transformation Rules:
  
  Check the transformation rules in the system to ensure they are correctly defined and that all necessary mappings are in place.
  If you have made changes to the transformation rules, ensure that the corresponding interface mappings are updated accordingly.
  
  
  
  Reconfigure Data Migration:
  
  If the configuration appears to be incorrect, consider reconfiguring the data migration process, ensuring that all necessary mappings and rules are defined.
  
  
  
  Transport Request Verification:
  
  If the mappings were supposed to be transported from another system, verify that the transport requests were successfully imported and that there were no errors during the transport process.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or notes related to the specific migration scenario you are working on. There may be specific guidelines or known issues that can help you resolve the error.
