Error:

- Error Code:21917122 

ShortMessage:All compatibilities invalid.

LongMessage:All compatibilities are invalid, Item not listed.



Resolution:

This error could be triggered when the EPID values, that were added for the particular item are no longer being used, invalid or have been replaced with newer and updated values and first, you can download eBay's latest MVL list and double check if the EPIDs are correct. If they aren't, then you can use the values for the particular compatibility combinations from the updated MVL file, but if they are correct and the above error is still being triggered and returned from the channel, please log a support ticket and provide us with the particular sku or guid and this would enable us to look into this and investigate further.
