The Shopware 6 Importer/Exporter comes with pre-made default profiles. Unfortunately, these default profiles do not include all possible fields and columns. Because adding each mapping and column one by one in the backend is pretty slow, it’s easier to just run the following two queries. After that, you will have full profiles including all available fields.
After executing these two queries against your DB, you might need to manually name the new profiles and switch languages to make sure they are named in all backend languages and save it.
Also, you should review that the mapping is correct, before using the new profiles in CSV imports/exports.
