A discrepancy report finds "dangling listings": items that are still listed on Discogs but are no longer in your Common Ground inventory, or are no longer valid there. If you leave them online, you risk selling a record twice and ending up in an order dispute.
How to use it
Generate a report here, or turn on daily auto-reports in Preferences › External services.
Wait for it to finish. This can take up to 15 minutes.
Unlist the dangling listings straight from the report.
If needed, re-list the affected items from your inventory.
Good to know
You can generate as many reports as you like, but you can only unlist items from the most recent one.
For large inventories, Discogs may email you about a ZIP export. You don't need to do anything.
Discogs connection issues sometimes leave a listing online after an Eshop or POS sale. Running reports regularly keeps your sync clean.
