• What is the cause and solution for SAP error message CNVHCM_PRESEL156 - Circular reference through ID &1; specify different ID in step &2 ?

  The SAP error message CNVHCM_PRESEL156 indicates that there is a circular reference in the configuration of the ID specified in the error message. This typically occurs in the context of data migration or transformation processes, particularly when dealing with the SAP HCM (Human Capital Management) module.
  Cause:
  The circular reference error arises when the system detects that the ID specified in the configuration is referencing itself or is part of a loop in the hierarchy. This can happen in various scenarios, such as:
  
  When defining relationships between organizational units, positions, or other entities where one entity is incorrectly set to reference another that eventually leads back to itself.
  In the context of data migration, if the mapping of IDs is not set up correctly, it can lead to circular dependencies.
  
  Solution:
  To resolve the CNVHCM_PRESEL156 error, you can follow these steps:
  
  
  Review the Configuration: Check the configuration settings for the IDs involved. Look for any relationships that may be causing the circular reference. Ensure that the IDs are set up correctly and do not point back to themselves.
  
  
  Modify the ID: In the step indicated in the error message (step &2), specify a different ID that does not create a circular reference. This may involve changing the hierarchy or the relationships between the entities.
  
  
  Check Dependencies: If the IDs are part of a larger structure, review the entire hierarchy to ensure that there are no other circular references that may not be immediately obvious.
  
  
  Testing: After making the necessary changes, test the configuration to ensure that the error no longer occurs and that the data migration or transformation process can proceed without issues.
  
  
  Consult Documentation: If you are unsure about the relationships or how to configure them correctly, refer to the SAP documentation or help resources related to HCM data migration.
  
  
  Seek Support: If the issue persists, consider reaching out to SAP support or consulting with an SAP expert who can provide guidance based on your specific configuration and requirements.
