This thread is resolved. Here is a description of the problem and solution.
Problem:
How can I populate a Post Title with the value of a Custom field when saving a post?
Solution:
You need Custom Code.
If you use CRED; you can make usage of the CRED API cred_save_data:
https://toolset.com/documentation/user-guides/cred-api/#csd
You would use WordPress API to
get_post_meta()
the Field's Values and update the
post_title
with it.
An example:

Keep in mind that Repeating Fields are arrays and therfore you need a complex
foreach()
on them, to get out the single values.
If you do not use CRED, you can use full WordPress API, it will just be the same as if you would use native WordPress fields.
Then you need to hook into the
wp_update_post()
https://developer.wordpress.org/reference/functions/wp_update_post/
The only to keep in mind here too is that a Types repeating Field is an array, and therefore you need to
foreach()
over it's stored values.
