• What is the cause and solution for SAP error message AXT_MODEL115 - Logical key of an active enhancement cannot be changed ?

  The SAP error message AXT_MODEL115, which states "Logical key of an active enhancement cannot be changed," typically occurs in the context of SAP enhancements or modifications where a logical key (or primary key) of an active enhancement is being altered. This can happen when you are trying to change the structure of an enhancement that is already active in the system.
  Cause:
  
  Active Enhancement: The enhancement you are trying to modify is currently active. In SAP, once an enhancement is activated, its logical key cannot be changed because it may affect the integrity of the data and the functionality of the application.
  Key Change Attempt: You may be attempting to change the logical key of a table or structure that is part of an enhancement, which is not allowed once the enhancement is active.
  
  Solution:
  
  
  Deactivate the Enhancement: If you need to change the logical key, you will first need to deactivate the enhancement. This can typically be done in the enhancement management tools in SAP (like transaction SE80 or SE11).
  
  Navigate to the enhancement in question.
  Deactivate it.
  Make the necessary changes to the logical key.
  Reactivate the enhancement after making the changes.
  
  
  
  Create a New Enhancement: If deactivating the enhancement is not feasible (for example, if it is in use in a production environment), consider creating a new enhancement with the desired logical key instead of modifying the existing one.
  
  
  Consult Documentation: Review the SAP documentation or notes related to the specific enhancement you are working with. There may be specific guidelines or restrictions regarding changes to logical keys.
  
  
  Testing: After making changes, ensure thorough testing is conducted to verify that the changes do not adversely affect the application or data integrity.
