• What is the cause and solution for SAP error message FDT_CORE257 - Reverting local appl. not possible; object already saved as non-local ?

  The SAP error message FDT_CORE257 indicates that there is an issue with reverting a local application object because it has already been saved as a non-local object. This typically occurs in the context of SAP Fiori or SAP UI5 applications when working with the Fiori Design Time (FDT) environment.
  Cause:
  The error arises when you attempt to revert changes made to a local object (like a UI5 application) that has already been saved as a non-local object. This means that the object has been committed to a different state or environment, and the system does not allow reverting to a local state because it is no longer in that state.
  Solution:
  To resolve this issue, you can consider the following steps:
  
  
  Check Object Status: Verify the status of the object you are working on. If it has been saved as a non-local object, you may need to work with that version instead of trying to revert to a local version.
  
  
  Use Version Control: If your development environment supports version control, check if you can revert to a previous version of the object that is saved in the repository.
  
  
  Manual Changes: If reverting is not possible, you may need to manually undo the changes you made to the object or create a new local version of the object if necessary.
  
  
  Consult Documentation: Refer to the SAP documentation or help resources for specific guidance on handling local and non-local objects in your version of SAP.
  
  
  Contact Support: If the issue persists and you cannot find a resolution, consider reaching out to SAP support for assistance. They may provide insights specific to your environment or version.
