• What is the cause and solution for SAP error message HCNUSAC_MSG112 - An entry already exists with the same key ?

  The SAP error message HCNUSAC_MSG112, which states "An entry already exists with the same key," typically occurs when there is an attempt to create or update a record in the SAP system that conflicts with an existing record. This error is common in various SAP modules, particularly in Human Capital Management (HCM) or when dealing with master data.
  Cause:
  
  Duplicate Entries: The most common cause is that the system is trying to create a new entry (such as a new employee record, payroll entry, etc.) that has the same key (like employee ID, personnel number, etc.) as an existing entry.
  Data Migration Issues: If data is being migrated from another system or imported in bulk, it may lead to duplicates if the data is not properly cleaned or validated before import.
  Incorrect Configuration: Sometimes, the configuration settings in the system may allow for duplicate entries, leading to conflicts when new data is entered.
  
  Solution:
  
  Check for Existing Records: Before creating a new entry, check the database for existing records with the same key. You can do this by using transaction codes like PA20 (Display HR Master Data) or PA30 (Maintain HR Master Data).
  Modify Existing Entry: If the entry already exists and you need to update it, use the appropriate transaction to modify the existing record instead of creating a new one.
  Data Cleanup: If you are importing data, ensure that the data is cleaned and validated to remove duplicates before the import process.
  Review Configuration: Check the configuration settings in the relevant module to ensure that they are set up correctly to prevent duplicate entries.
  Consult Documentation: Refer to SAP documentation or support notes related to the specific module you are working with for additional guidance on handling this error.
  
  Related Information:
