• What is the cause and solution for SAP error message RAP_CMP_CHECKS158 - ObjectModel.action: action &1 of entity &2, property &3 changed ?

  The SAP error message RAP_CMP_CHECKS158 typically occurs in the context of the SAP RAP (Rapid Application Programming) model when there is an issue with the consistency of the data being processed in an action of an entity. This error indicates that a property of an entity has been changed in a way that is not allowed or expected during the execution of an action.
  Cause:
  The error message RAP_CMP_CHECKS158 is triggered when:
  
  An action is trying to modify a property of an entity that has already been changed or is in an inconsistent state.
  The action is not properly defined in terms of the expected input or output parameters.
  There may be a violation of business logic or constraints defined in the RAP model.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Action Definition: Review the action definition in your RAP model to ensure that it is correctly defined and that the expected parameters are being passed correctly.
  
  
  Review Entity State: Ensure that the entity state is consistent before the action is executed. If the entity has been modified elsewhere in the code or by another action, it may lead to this error.
  
  
  Debugging: Use debugging tools to trace the execution flow and identify where the property change is occurring. This can help you pinpoint the exact cause of the inconsistency.
  
  
  Business Logic Validation: Validate the business logic associated with the action to ensure that it allows for the changes being made. If there are constraints that are being violated, you may need to adjust the logic accordingly.
  
  
  Check for Concurrent Modifications: If multiple processes or users are trying to modify the same entity simultaneously, it may lead to conflicts. Implement proper locking mechanisms or handle concurrency appropriately.
  
  
  Consult Documentation: Refer to the SAP documentation for RAP and the specific action you are working with to ensure compliance with the expected behavior.
