SAP Error Message - Details

• Message type: E = Error

• Message class: SADL_CTR_T_VIOLATION - Contract Test Violation Messages

• Message number: 005

• Message text: RAP Contract Violation: Response with duplicate keys for READ with &1

What causes this issue?

READ Contract:
Entries in MAPPED, FAILED and RESULT contain always a sub-set of the
input keys. Input keys which are not part of RESULT have to be part of
FAILED.

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

The contract of the following read operation has been violated for
entity &V2&:
The behavior implementation returned duplicate keys in the RESULT,
although the result must not contain duplicate keys.
Info:
Corresponding entries in reported can be returned, but this is not
mandatory. Additional entries can be reported, referring to keys outside
of the input keys.

System Response

How to fix this error?

Please check the response of your behavior implementation and adopt it
according to the contract.

• What is the cause and solution for SAP error message SADL_CTR_T_VIOLATION005 - RAP Contract Violation: Response with duplicate keys for READ with &1 ?

  The SAP error message SADL_CTR_T_VIOLATION005 indicates a violation related to the RAP (Rapid Application Programming) model, specifically concerning a contract that has been defined for a READ operation. The error message states that there is a response with duplicate keys for a READ operation, which means that the system has encountered multiple records that share the same key value when it was expected to return a unique record.
  Cause:
  
  Duplicate Data: The most common cause of this error is that the underlying data source (e.g., database table or view) contains duplicate entries for the key fields that are supposed to be unique.
  Incorrect Data Model: The data model defined in the RAP might not be correctly set up to ensure uniqueness for the keys being queried.
  Inconsistent Data: There may be inconsistencies in the data due to improper data entry, data migration issues, or lack of constraints in the database.
  
  Solution:
  
  
  Check for Duplicates: 
  
  Query the underlying database table or view to identify any duplicate entries for the key fields. You can use SQL queries to find duplicates.
  Example SQL query to find duplicates:
  SELECT key_field, COUNT(*)
  FROM your_table
  GROUP BY key_field
  HAVING COUNT(*) > 1;
  
  
  
  
  Data Cleanup: 
  
  If duplicates are found, you will need to clean up the data. This may involve deleting or merging duplicate records to ensure that each key is unique.
  Ensure that the data integrity is maintained after cleanup.
  
  
  
  Review RAP Model: 
  
  Review the RAP model definition to ensure that the keys are correctly defined and that the model is set up to handle unique records.
  Check the annotations and definitions in the behavior definition and service definition to ensure they align with the expected data structure.
  
  
  
  Implement Constraints: 
  
  If applicable, implement database constraints (like unique indexes) to prevent future duplicates from being created.
  
  
  
  Testing: 
  
  After making changes, test the READ operation again to ensure that the error is resolved and that the system returns the expected results.
  
  
  
  Related Information:
  
  RAP Model: The RAP model is a framework in SAP for building business applications using a service-oriented architecture. Understanding the principles of RAP can help in troubleshooting issues related to data access and manipulation.
  SAP Notes: Check for any relevant SAP Notes or documentation that may provide additional insights or updates related to this error message.
  Debugging: If the issue persists, consider using debugging tools in SAP to trace the execution of the READ operation and identify where the duplicates are being introduced.
  
  By following these steps, you should be able to resolve the SADL_CTR_T_VIOLATION005 error and ensure that your RAP application functions correctly.
