field don't appear as hyperlink after I mapped them

Hello!

I have two entities A and B.

A have a lot of records and each record have a unique text field named NUMBER.

Relationship between B and A is N:1.

I created a text field named NUMBER in entity B and I've mapped it to the NUMBER in entity A

After I imported a list of record from an excel file to entity B, NUMBER in each record appeared in black text.

How can I change this so that NUMBER in entity B would appear as hyperlink? ( so that it direct me to the corresponding record in entity A when I click on it)

Thanks in advance!
