How do you record import of service; rais tax libility, claim tax credit for a product purchased from provider outside india

Hi!

I was looking to enter:
1. Import of service done by us (a software purchased from a service provider outside India)
2. Raise Tax liability
3. Claim Tax credit for it

However I donot find any ledgers created for purchase if we import a service.

Please advice how can we proceed on this to file our  GST3B.

Best regards
