JTL Connector: How to prevent overwriting during sync!

If you are using Shopware and JTL and have created a free text field in Shopware that you want to configure independently of JTL, it is possible that this attribute will be overwritten by the JTL Connector every time the article is synced and will have the value zero.

On the one hand, this setting makes sense so that data can only be changed and edited in JTL and to have a consistent database. On the other hand, however, it leads to problems if certain fields are to be set directly in Shopware that are not known to JTL. We have a solution for this - do you need more help with Shopware? The EXWE team will be happy to help you - just contact us by e-mail or phone.

The solution

To fix the whole thing or change the behavior, you have to look in the config.json of the JTL Connector plugin. You can find it under

engine/Shopware/Plugins/Community/Frontend/jtlconnector/
config/config.json.

There is a setting "null_undefined_attributes". You must set this to false under product, push to prevent your attributes from being overwritten.

The entry could then look like this, for example:

"product": { "push": { "null_undefined_attributes": false, "article_detail_preselection": false } },
