How to Pass PR Number from SCM to CRM via Button

Summary:

I am working on Oracle Fusion SCM, specifically on the Purchase Requisition page.
I need to add a button or link that, when clicked, passes the PR number to Oracle Fusion CRM and opens a Custom Object page with the PR number auto-populated in a field.

Content (please ensure you mask any confidential information):

We have a business requirement to enable users to navigate from the Purchase Requisition page in Fusion SCM to a Custom Object in Fusion CRM.
When the user clicks a button on the PR page, the system should capture the PR number and pass it to CRM, where a new record should be opened with the PR number automatically populated in a custom field.
