Hi @DKO-dS and thanks for your message. We are aware of the problem, in fact we added a validation of this in v2, see https://github.com/FACT-Finder-Web-Components/magento2-module/blob/release/2.x/src/Model/Export/Catalog/AttributeValuesExtractor.php#L47

On the other hand, why would a user want to export specifically these attributes? In case you need this data, it would be more appropriate to write a custom product field and handle the export there. These are special cases in Magento, and are not exported in general.

We were thinking about excluding some of the attributes from the selector, but again there is no real universal logic that we can use for it, so we did not proceed. Do you have any ideas on how to solve this in a pragmatic way?

Hi @fmarangi,

categories and tier prices are necessary.
Categories are used for searching and the filter navigation.
Tier prices are used for customer group prices.

Currently in the oxid version both will be transferred to Factfinder.

Categories are already exported, see https://github.com/FACT-Finder-Web-Components/magento2-module/blob/master/src/Model/Export/Catalog/ProductField/CategoryPath.php

As for tier prices, you are right, but so far we had no real use case for it. Tier prices are in general not so trivial in Magento. In case you need this feature, we can develop it together and add this to the repo, but it will need a custom field anyway, since the format of this generic extractor would not work correctly in FF.
