• What is the cause and solution for SAP error message FUNC_ADT026 - The function module &1 is not locked, save not possible ?

  The SAP error message FUNC_ADT026 indicates that a function module is not locked, which prevents you from saving changes to it. This typically occurs in the ABAP Development Tools (ADT) environment when you attempt to modify a function module that is currently not locked for editing.
  Cause:
  
  Not Locked for Editing: The function module you are trying to edit is not locked, meaning that another user or session may be editing it, or it has not been locked properly in the system.
  Transport Request Issues: If the function module is part of a transport request that is not properly configured or is in a state that does not allow changes, you may encounter this error.
  Authorization Issues: You may not have the necessary authorizations to lock the function module for editing.
  
  Solution:
  
  
  Check Lock Status: 
  
  Use transaction code SE37 (Function Builder) to check the lock status of the function module. If it is locked by another user, you may need to wait until they release the lock.
  You can also use transaction SM12 to view and manage locks in the system. If you find that the function module is locked by a user who is no longer active, you may need to delete the lock (if you have the necessary authorizations).
  
  
  
  Lock the Function Module: 
  
  If you have the necessary authorizations, try to lock the function module manually before making changes. This can be done in the Function Builder (SE37) by selecting the function module and clicking on the lock icon.
  
  
  
  Check Transport Request: 
  
  Ensure that the function module is assigned to a transport request and that the request is in a state that allows changes. If necessary, create a new transport request.
  
  
  
  Authorization Check: 
  
  Verify that you have the appropriate authorizations to edit and lock function modules. You may need to consult with your SAP security team if you suspect authorization issues.
  
  
  
  Restart ADT: 
  
  Sometimes, simply restarting the ABAP Development Tools (ADT) or your SAP GUI session can resolve temporary issues related to locks.
