  The SAP error message KMAT_MIGR122 indicates that there are duplicate instances of a variant in the configuration of an IBase (Installation Base) object. This typically occurs during the migration or configuration of configurable materials (KMAT) in SAP, particularly when dealing with variant configuration.
  Cause:
  The error arises when the system detects that a specific variant (identified by &1) has multiple entries or instances (identified by &2) in the configuration. This can happen due to:
  
  Data Migration Issues: During data migration, if the same variant is incorrectly duplicated in the source data, it can lead to this error.
  Configuration Errors: Manual errors in the configuration of the product or variant can lead to duplicates being created.
  Inconsistent Data: If the data in the system is not consistent or has been manually altered without proper checks, it can lead to duplicates.
  
  Solution:
  To resolve the KMAT_MIGR122 error, you can follow these steps:

  Data Cleanup:
  
  Once duplicates are identified, you need to decide which entries to keep and which to delete. This may involve consulting with business stakeholders to ensure that no critical data is lost.
  Use appropriate SAP transactions (like SE14 for database table adjustments) to remove or correct the duplicate entries.
  
  
  
  Reconfigure:
  
  If the duplicates are due to configuration errors, reconfigure the variant in the system to ensure that it is set up correctly without duplicates.
