Trying to create Z class to work on TIFF files

Hi All,

I have a requirement where the users makes a data entry operation by choosing a specific folder.

I am able to lock the files of the current user and other user who are viewing by using lock object. Everything works fine.

I am using the class CL_GUI_FRONTEND_SERVICES to open the file and also i am able to delete the file once the transaction is over.

The issue comes here:

on deleting the current file after data entry operation the next file is automatically getting populated regardless of the other user is viewing or not.  So duplication is happening.

Is there a way to close the file before deletion?. I am not restricted particular extension types it can PDF, TIFF, JPG etc..

If yes it solves my problem or else then i am looking into other options as well  like given by Thomas Jung in below blog.
