How can I programmatically change parameters and body in SOAPUI?

I have the below REST API:

Endpoint: https://fa-ewwd-saasfaprod1.fa.ocs.oracle.com

Resource: /hcmRestApi/resources/11.13.18.05/userAccounts/{{USER_GUID}}

Parameter Name: {{USER_GUID}}Value: 18B2E68E6C162

JSON:

{"PersonNumber" : "232732"}

This is working fine but I do not know how to loop this in SOAPUI. My research tells me to use a Groovy script under test cases but I can not understand how.

How can I run a loop 100 times and update the Parameter in the URL and the PersonNumber each loop?

I am new to SOAPUI.
