SBWP - Documents from shared folder are automatically moving to trash folder

Hi Experts,

We have recently encountered an issue in transaction SBWP of our ECC Production system, where many files are automatically getting deleted from the original folders and moved to Shared Trash folder. As of now, there are approximately ~25K such files.

As per our initial troubleshooting, it was observed that the files are automatically picking up some expiration date, but we could not figure out where from the date is being picked up. After removing the expiration date, the files are moving back to their respective folders, but after sometime, again the same issue is happening.

We need to retrieve all documents/files in original folders. Can you please help here? Thanks
