Unable to select Files for Delete Program on SARA-WORKITEM at

Hello Experts!

I would like to ask for a help, I'm trying to delete a file at transaction code SARA and object WORKITEM, but it says that besides the job didnt fail, when writing the file, i can't select it for deleting.

It has only one message that says "Not stored" and has this "yellow ray" locking the selection.Those screens appers when i click on the "Archive Selection" button.

Anyone have any ideas?

Thanks!
