eBay LMS ReviseInventoryStatus bug

There appears to be a problem with revision of multi-variation listings through Large Merchant Services. If trying to revise the price on a number of SKUs on one listing the process reports the change has been successfully carried out, but in reality the price isn’t altered.

This shouldn’t affect most users – it’s likely to affect you if you’re using a multi-channel service provider who uses the Large Merchant Services API calls.

eBay have confirmed it is a bug at their end – which seems to be sporadic as it doean’t happen every time – sometimes the pricing updates works fine. They say that “It looks like this issue is happening because of a race condition as multiple variations of the same item were being revised at the same time , but that is still a problem at our end.

The call causing the issue is “ReviseInventoryStatus” and if it’s failing for you then the only current solution is to execute the call for a single SKU at a time – this could mean hundreds of revisions need to be submitted individually for a single multi-variation listing instead of just one.

eBay expect to have a fix in place some time around the 8th of May.

I have my doubts that this is a problem with LMS or that it is even relatively new. I reported exactly the same issue except not through LMS over 3 1/2 years ago and was just told to pause between every ReviseInventoryStatus call because multiple simultaneous updates to the same listing is not supported. Instead I have to spend possibly 100s of hours per year waiting for ReviseInventoryStatus to finish before making the next call whenever multiple variations are being revised within the same timeframe. I suspect LMS was rewritten recently to act more like my own apps which operate with a high degree of parallelism. This has likely just made the bug obvious to some rather large seller or developer. Here are the three times I've publicly mentioned this over the years: https://www.x.com/developers/ebay/forums/technical-questions-ebay-apis-require-user-token-trading-feedback-best-match/cant-update-multiple-mvl-children-listings-parallel https://www.x.com/developers/ebay/forums/developer-product-feedback/wishlist/allow-reviseinventorystatus-alter-multiple-variations-same-listing. https://tamebaynew.wpengine.com/2012/08/ebay-overcharge-120-on-multiple-varation-purchase.html Even Marshall Smith from Channel Advisor acknowledged it in response to my complaint above.
