Smart SAP Assistant

• What is the cause and solution for SAP error message CND_MAINT_LTD_API027 - Condition record could not be added due to DUPLICATE KEY of "KNUMH". ?

  The SAP error message CND_MAINT_LTD_API027 indicates that there is an attempt to add a condition record, but it fails due to a duplicate key issue related to the field KNUMH. This typically means that the system is trying to create a condition record with a key that already exists in the database.
  Cause:
  
  
  Duplicate Condition Record: The most common cause is that a condition record with the same key (KNUMH) already exists in the system. This can happen if:
  
  The same condition record is being created multiple times.
  There is a data entry error where the same key is being reused.
  A program or batch job is trying to insert records without checking for existing ones.
  
  
  
  Data Migration Issues: If data is being migrated from another system or if there are bulk uploads, it’s possible that duplicates were introduced during this process.
  
  
  Incorrect Logic in Custom Code: If there is custom code (like user exits or BAdIs) that handles condition records, it might not be checking for existing records properly before attempting to create new ones.
  
  
  Solution:
  
  
  Check Existing Records: Before attempting to add a new condition record, check the existing records in the relevant condition table (e.g., KONV for pricing conditions) to see if a record with the same KNUMH already exists.
  
  
  Modify the Input Data: If duplicates are found, modify the input data to ensure that you are not trying to create a record that already exists.
  
  
  Error Handling in Custom Code: If you have custom logic, ensure that it includes checks for existing records before attempting to create new ones. Implement error handling to manage such situations gracefully.
  
  
  Data Cleanup: If duplicates exist due to data migration or other issues, consider cleaning up the data to remove or consolidate duplicate records.
  
  
  Consult SAP Notes: Check for any relevant SAP Notes that might address this specific error or provide guidance on handling condition records.
  
  
  Related Information:
  
  KNUMH: This is the key field for condition records in SAP, and it uniquely identifies a condition record.
  Transaction Codes: You can use transaction codes like VK11 (Create Condition) or VK12 (Change Condition) to manually check and manage condition records.
  Debugging: If the error occurs during a program execution, consider debugging the program to identify where the duplicate key issue arises.
  
  By following these steps, you should be able to resolve the error and prevent it from occurring in the future.
