• What is the cause and solution for SAP error message RAP_RUNTIME010 - Unmanaged query API violation: Response setter method called twice ?

  The SAP error message RAP_RUNTIME010 indicates that there is a violation related to the unmanaged query API in the context of the SAP RAP (Rapid Application Programming) model. Specifically, this error occurs when a response setter method is called more than once for a single response object, which is not allowed.
  Cause:
  The error typically arises from one of the following scenarios:
  
  
  Multiple Calls to Setter Methods: The code logic may inadvertently call a setter method for a response object multiple times. This can happen if there are loops or conditions that lead to the setter being invoked more than once.
  
  
  Incorrect Data Handling: If the data being processed is not managed correctly, it may lead to situations where the same response object is being modified multiple times.
  
  
  Concurrency Issues: In some cases, if multiple threads or processes are trying to modify the same response object, it can lead to this error.
  
  
  Solution:
  To resolve the RAP_RUNTIME010 error, consider the following steps:
  
  
  Review the Code: Check the implementation of the unmanaged query API and ensure that each response setter method is called only once per response object. Look for loops or conditional statements that might lead to multiple invocations.
  
  
  Debugging: Use debugging tools to trace the execution flow and identify where the setter method is being called multiple times. This can help pinpoint the exact location in the code that needs to be corrected.
  
  
  Refactor Logic: If the logic is complex, consider refactoring it to ensure that each response object is only set once. You may need to aggregate data before setting it to the response object.
  
  
  Concurrency Control: If the issue is related to concurrency, implement proper locking mechanisms or use thread-safe practices to ensure that the response object is not modified by multiple threads simultaneously.
  
  
  Testing: After making changes, thoroughly test the application to ensure that the error is resolved and that the response object is being populated correctly.
  
  
  Related Information:
