P: Does not remember original file number when exporting an AI Denoise Image

Over 90 % of the images in my LrC Catalog are original RAW images from digital Cameras. I do not use DNG files in my normal workflow and I do not Automatically write Metadata to XMP.

 I just used the Copy as DNG at import as a reason why Adobe does not retain the original raw image name in the DNG file created during the Denoise process. LrC does not change the original imported files when editing.

I use the original CR2/CR3 (and some older ARW) files. I don't want to convert everything to DNG, only the files which I choose to retouch. I'm already using several terabytes of drive space.

@ExUSA , Ok , so there are lots of users who use the Copy as DNG at import to LrC ( its an option Adobe have recommended for many years) the file is a raw DNG and users can apply the Denoise feature to the DNG image they will also get another image that will have the (-Enhanced-NR.dng. This new image will sit in the same folder as the RAW  DNG it's required since the Computer OS will not allow filed with the same name and will require a change to the name.

After you do Denoise you will have two Image files the Original file and a new Denoised image file. 

I copy files off the memory card using the Finder, and then import them from my hard drive into my Lightroom catalog.

@ExUSA , you stated "I'm exporting in place, not directly off the memory card.".
Could you explain, I am not sure exactly what you mean?

I'm not changing filename and I'm exporting in place, not directly off the memory card. Maybe this is the issue? I have probably 350k RAW files so I hope that isn't it.

@ExUSA , I agree with @johnrellis, post see the screen capture from my Windows system. I am using LrC 14.2.

Note

Original file name (created when Denoise was done) P3054344-241-Enhanced-NR.dng.

Original Raw Filename (as imported into LrC  extension of 241 added) P3054344-241-ORF.

Preserved File Name (as created in the camera) P3054344.ORF.

Yes I assume that Enhance is not writing the correct info. This happens with every RAW file that I try (I've tested this with numerous files), its not specific to any one. I'll put one online tonight that you can look at.

The XMP you posted has the field dng:OriginalRawFileName but not the field XMP:PreservedFileName, which is normally added by Photo > Enhance. It's the latter that the Rename token Preserved File Name reads.

To make further progress on understanding what's going wrong, I'd need the original raw and the DNG.
