Thanks Oliver,
Yes you got it correct.
I forgot to mentioned that some of the fields are extended from SDK(only 4 fields), and rest of the fields created by KUT.
If we request for new test tenant where solution from production will be copied into it, then Can we access SDK fields?
If so, can I create patch in new test tenant and after the chages can I deploy the solution without any problem?
Thanks
