• What is the cause and solution for SAP error message LOBM_ODATA_MSG035 - Duplicate key ?

  The SAP error message LOBM_ODATA_MSG035 indicates a "Duplicate key" issue when working with OData services in SAP. This error typically arises when there is an attempt to create or update an entity in the OData service, but the key (or unique identifier) for that entity already exists in the database.
  Cause:
  
  Duplicate Entry: The most common cause is that the data being sent to the OData service contains a key that already exists in the database. This can happen during create or update operations.
  Incorrect Data Handling: If the application logic does not properly handle the uniqueness of keys, it may inadvertently attempt to insert a duplicate.
  Concurrency Issues: If multiple processes are trying to create or update the same entity simultaneously, one may succeed while the other fails due to the duplicate key.
  Data Migration Issues: During data migration or import processes, if the same key is used for multiple records, this error can occur.
  
  Solution:
  
  Check Existing Data: Before creating or updating an entity, check the database to ensure that the key does not already exist. This can be done by querying the relevant table.
  Modify Key Values: If you are trying to create a new entity, ensure that the key value is unique. You may need to generate a new key or modify the existing one.
  Handle Concurrency: Implement proper locking mechanisms or transaction handling to avoid concurrent modifications that could lead to duplicate keys.
  Error Handling in Application: Enhance the error handling in your application to catch this specific error and provide meaningful feedback to the user or log it for further analysis.
  Data Cleanup: If the error is due to data inconsistencies, consider cleaning up the data in the database to remove duplicates or resolve conflicts.
  
  Related Information:
  
  OData Services: Understanding how OData services work in SAP can help in troubleshooting issues related to data operations.
