Hi Pawan,
Just to check:
- you have created custom fields in environment 1;
- you have created personalization in environment 1;
And you want to have this available in environment 2. To do this, you imported the personalization in environment 2?
In order to have the custom fields in the second environment, those needs to be setup in that environment also.
In order to have those custom fields to be available in the second environments data entities, you need to apply the changes.

Hopefully this helps.
with regards,
Erik de Boer
