In the following article you will find a list of the most common MALL XML feed error messages and their meaning. Based on this information, fixing errors in the MALL XML feed will be easier.
For instructions on where to find the list of error messages, see our article Inserting MALL XML feeds into the portal, working with intervals and error messages.
To fix error messages, please follow the rules described in instructions for building MALL XML feeds.
The list of errors below is also valid for partners with the API connection type. These messages may return in response to your call. Consequently, you need to modify the call structure to remove the message.
Important:
Duplication of IDs in your feed is not possible. If you enter the same product ID multiple times in your feed, the system will only upload one of these products, all others will be ignored. There is no error message about this in the log, so make sure your IDs are unique. If you have multiple variants of one product, use the option to create variant products according to our Documentation.
Warning:
The error log does not identify which specific product is generating the error, so please always check the settings in the entire feed.
You will find a maximum of 1000 errors in the log. If the log shows this number, it is possible that your feed shows more. In this case, you need to fix the errors one at a time.
