Hello,

Toolset repeatable field group is based on one-to-many relationship, so each item of repeatable field group is also a post, the post type slug is same as repeatable field group slug.

And Toolset Views/Blocks plugin is using WordPress class WP_Query to query posts, you can order the result by custom fields of current post type, you can not order the result by another post type's fields:
https://developer.wordpress.org/reference/classes/wp_query/#order-orderby-parameters
‘meta_value‘ – Note that a ‘meta_key=keyname‘ must also be present in the query

So it is not possible with Toolset plugins, you might consider to move the custom date field from repeatable field group into the post

hi, thx for the answer. But is it possible to copy a field from rpf to an field in parent when i save it? Then i can sort it.. - Or a workaround for this?

Unfortunately, there isn't such kind of built-in feature within Toolset plugins, one post can have multiple instance items in repeatable field group, so it won't be easy to move an RFG field into parent post, you might need to move it manually.

hey - yes i recognize that toolset dont have a build-in-feature for that. But iam searching for a method to do this. If i find a snippet like something to update the Parent post on save - perhaps this way is good: https://developer.wordpress.org/reference/hooks/save_post/

You dont know a snippet for something?

best regards - alex

Yes, it is possible with custom codes, for example, when you save a RFG item, use action hook save_post to trigger a PHP function:
https://developer.wordpress.org/reference/hooks/save_post/
In this PHP function, get the RFG item custom date field value:
https://developer.wordpress.org/reference/functions/get_post_meta/
Get the related(parent) post's ID:
https://toolset.com/documentation/customizing-sites-using-php/post-relationships-api/#toolset_get_related_post
Update the related(parent) post's field value to what you want:
