TYPO3 Core

Okay, there is a workaround anyway with existing markers.

I'll open an issue for the docs instead.

Actually, it is mentioned in a changelog for v11:
https://docs.typo3.org/c/typo3/cms-core/main/en-us/Changelog/11.4/Feature-94662-AddPlaceholderForSiteConfigurationInForeignTableWhere.html

So, if this is not implemented, it should be removed there.

Patch set 1 for branch main of project Packages/TYPO3.CMS has been pushed to the review server.
It is available at https://review.typo3.org/c/Packages/TYPO3.CMS/+/82333

Hi Chris, I fear there is a misunderstanding regarding the reported issue. The feature does not work for the AddRecord wizard but does work for the foreign_table_where option as advertised in the changelog. I just checked this and there are also tests in place, covering this scenario, see: https://github.com/TYPO3/typo3/blob/main/typo3/sysext/backend/Tests/Functional/Form/FormDataProvider/TcaSelectItemsTest.php#L1079
