  The SAP error message /UIF/LREP_CORE_MSG019 indicates that you are trying to make changes to a draft mode file outside of the designated DRAFT layer. This typically occurs in the context of SAP Fiori or UI5 applications where draft handling is implemented.
  Cause:
  The error arises when:
  
  You attempt to edit or maintain a draft version of an object (like a UI5 application or a Fiori app) in a layer that is not designated for drafts (e.g., the "Main" or "Custom" layer).
  The system enforces that draft changes can only be made in the DRAFT layer to ensure that the integrity of the main application is maintained.
  
  Solution:
  To resolve this error, you should:
  
  
  Switch to the DRAFT Layer: Ensure that you are working in the DRAFT layer when making changes to draft files. You can do this by:
  
  Navigating to the relevant transaction or application where you are making changes.
  Selecting the DRAFT layer from the layer selection options (if available).
  
  
  
  Save Changes in the Correct Layer: After switching to the DRAFT layer, make your changes and save them. This should allow you to maintain the draft without encountering the error.
  
  
  Check User Permissions: Ensure that you have the necessary permissions to access and modify objects in the DRAFT layer.
  
  
  Consult Documentation: If you are unsure about how to switch layers or manage drafts, refer to the SAP documentation or help resources specific to the application you are working with.
  
  
  Related Information:
  
  Draft Handling in SAP: Understanding how draft handling works in SAP applications can help you avoid similar issues in the future. Drafts are typically used to allow users to make changes without affecting the live version of the application until they are ready to publish.
  SAP Notes and Support: If the issue persists, consider checking SAP Notes or reaching out to SAP support for further assistance. There may be specific patches or updates that address related issues.
  Training and Resources: Familiarize yourself with the SAP Fiori or UI5 development environment, as well as best practices for managing drafts and layers.
