How To Fix SADL_CTR_T_VIOLATION006 - RAP Contract Violation: Check could not be executed due to duplicate keys

SAP Error Message - Details

• Message type: E = Error

• Message class: SADL_CTR_T_VIOLATION - Contract Test Violation Messages

• Message number: 006

• Message text: RAP Contract Violation: Check could not be executed due to duplicate keys

What causes this issue?

The contract does not allow duplicate records in the response. To
fulfill the contract, the results of the behavior implementation need to
be compared against the data on the database, which contains non-unique
keys. A Key must exclusively identify a record.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

Define a proper key or ensure the database contains unique keys.

• What is the cause and solution for SAP error message SADL_CTR_T_VIOLATION006 - RAP Contract Violation: Check could not be executed due to duplicate keys ?

  The SAP error message SADL_CTR_T_VIOLATION006 indicates a violation related to the RAP (Rapid Application Programming) model, specifically concerning contract checks that could not be executed due to duplicate keys. This error typically arises when there are multiple entries in the database that share the same key, which violates the uniqueness constraint expected by the system.
  Cause:
  
  Duplicate Entries: The primary cause of this error is the presence of duplicate entries in the underlying database table that the RAP model is trying to access. This can happen due to data inconsistencies, incorrect data migrations, or issues during data entry.
  Incorrect Key Definition: The key definition in the RAP model may not align with the actual data structure, leading to conflicts when the system attempts to enforce uniqueness.
  Concurrency Issues: If multiple transactions are trying to insert or update records simultaneously, it may lead to temporary duplicates.
  
  Solution:
  
  
  Identify Duplicates: 
  
  Use SQL queries to identify duplicate entries in the relevant database table. For example:
  SELECT key_field, COUNT(*)
  FROM your_table
  GROUP BY key_field
  HAVING COUNT(*) > 1;
  
  Replace key_field and your_table with the actual key field and table name.
  
  
  
  Data Cleanup: 
  
  Once duplicates are identified, you will need to decide how to handle them. This could involve deleting or merging duplicate records based on business rules.
  Ensure that the data is consistent and adheres to the expected uniqueness constraints.
  
  
  
  Review Key Definitions: 
  
  Check the key definitions in your RAP model to ensure they are correctly defined and match the underlying database structure.
  Adjust the model if necessary to align with the actual data.
  
  
  
  Implement Data Validation: 
  
  Implement validation checks in your application logic to prevent the insertion of duplicate records in the future.
  Consider using unique constraints at the database level to enforce data integrity.
  
  
  
  Testing: 
  
  After making changes, thoroughly test the application to ensure that the error no longer occurs and that the data integrity is maintained.
