• What is the cause and solution for SAP error message MSG_CL_ER135 - Entry with key-value combination already exists: &1 - &2 ?

  The SAP error message MSG_CL_ER135 with the description "Entry with key-value combination already exists: &1 - &2" typically indicates that there is an attempt to create or update an entry in a table or a data structure where a unique key constraint is violated. This means that the combination of the specified key values already exists in the database, and the system does not allow duplicate entries for that key.
  Cause
  The error can occur due to several reasons:
  
  Duplicate Data Entry: You are trying to insert a record that has the same key-value combination as an existing record.
  Data Migration Issues: During data migration or upload processes, duplicate records may be inadvertently introduced.
  Incorrect Logic in Custom Code: If there is custom ABAP code or enhancements that manipulate data, they may not be handling existing records correctly.
  Configuration Issues: In some cases, configuration settings may lead to attempts to create duplicate entries.
  
  Solution
  To resolve this error, you can take the following steps:
  
  
  Check Existing Records: 
  
  Use transaction codes like SE16 or SE11 to check the relevant table for existing entries with the same key-value combination. This will help you identify if the record already exists.
  
  
  
  Modify Your Input: 
  
  If you are trying to create a new entry, ensure that the key-value combination you are using is unique. Modify your input data accordingly.
  
  
  
  Update Instead of Insert: 
  
  If the intention is to update an existing record, ensure that you are using the correct update logic instead of trying to insert a new record.
  
  
  
  Review Custom Code: 
  
  If the error arises from custom ABAP code, review the logic to ensure it checks for existing records before attempting to insert new ones.
  
  
  
  Data Cleansing: 
  
  If this error occurs during data migration, consider cleansing the data to remove duplicates before the migration process.
  
  
  
  Consult Documentation: 
  
  Check SAP documentation or notes related to the specific module or functionality you are working with for any known issues or additional guidance.
