Title: Using MPN Last modified: April 24, 2020 --- # Using MPN * Resolved [rcanny](https://wordpress.org/support/users/rcanny/) * (@rcanny) * [6 years, 1 month ago](https://wordpress.org/support/topic/using-mpn/) * We have a mixture of products with GTIN buy many that only have MPN (manufacturer part number). I set up the plugin to use MPN, but the structured data result is placing the data into the GTIN field, not MPN. See snip below: description Medium duty roller conveyor by Ultimation. 27″ wide x 24″ BF x 10′ Long. Contact us to quote different sizes.

Google issues a warning that entering an MPN data into a GTIN field is wrong.

Thanks for the reply! Yes, that’s what I did, and that’s what I expected to see. But when I do that for both a simple product and for a variable product, it’s getting added to the GTIN field, not the MPN field * Here’s the new one I just made: [https://pasteboard.co/J5t8cuM.png](https://pasteboard.co/J5t8cuM.png) * And here’s my settings where I have selected mpn: [https://pasteboard.co/J5t9XhT.png](https://pasteboard.co/J5t9XhT.png) * I am also using WPSSO Schema JSON-LD Markup plugin. Maybe this is causing the problem?

When I turn off the WPSSO plugin, then your plugin works correctly for mpn. * [https://pasteboard.co/J5tfhMz.png](https://pasteboard.co/J5tfhMz.png) * I’ve turned off WPSSO Schema JSON-LD Markup (Premium) for the moment and will refer the developer of it to this thread. * Thank you! * Plugin Author [Emanuela Castorina](https://wordpress.org/support/users/kreamweb/) * (@kreamweb) * [6 years, 1 month ago](https://wordpress.org/support/topic/using-mpn/#post-12730841) * ok! let me know! * [JS Morisset](https://wordpress.org/support/users/jsmoriss/) * (@jsmoriss) * [6 years, 1 month ago](https://wordpress.org/support/topic/using-mpn/#post-12730954) * FYI – The WPSSO Core Premium plugin was reading the ‘_wpm_gtin_code’ metadata value into the Schema ‘gtin’ property. * As of WPSSO Core Premium v7.1.0 (released this morning), the ‘wpm_pgw_structured_data_field’ setting value is now checked to assign the ‘_wpm_gtin_code’ metadata value to the correct Schema property. * You can click the “Check Again” button on the WordPress Dashboard > Updates page or the “Check for Updates” button from the SSO > Tools and Actions page to get the latest Premium update information and refresh the local update cache immediately. * js. * Thread Starter [rcanny](https://wordpress.org/support/users/rcanny/) * (@rcanny) * [6 years, 1 month ago](https://wordpress.org/support/topic/using-mpn/#post-12730976) * JS and Emanuela, Thanks very much. Confirming that with the update to v7.1.0 that everything is now working as it should. MPN is in the correct location and no errors. * [https://pasteboard.co/J5twZpL.png](https://pasteboard.co/J5twZpL.png) * Thanks all.

Once removed all is back to normal. * Plugin Author [Emanuela Castorina](https://wordpress.org/support/users/kreamweb/) * (@kreamweb) * [6 years ago](https://wordpress.org/support/topic/using-mpn/#post-12741811) * [@kitgrow](https://wordpress.org/support/users/kitgrow/) I’ve tried that plugin, it removes the WooCoommerce Structure Data to add its data , for this reason you don’t see the GTIN code.
