Create a report for Tracking Lead movement or management in Creatio Reports

Hi Everyone,

I am trying to build a weekly summary report in Creatio to track key lead milestones, and I am facing an issue with tracking stage movement accurately.

Requirement:

• Report should show leads moving from ABC to DEF
• Leads marked as Qualified or Disqualified
• Opportunities moved to Closed Won or Closed Lost
• Weekly summary only (not individual notifications)

The issue I am facing is specifically with tracking:
“Leads moved from  ABC to DEF

In the report setup, I can filter current fields like:

• Source
• SBU
• Lead Stage
• Status

I am trying to understand:

1. What is the best way to track field transitions in Creatio reports?
2. Is it better to create a custom object via business process to store stage movement history?
3. Has anyone implemented similar milestone tracking reports?

Any guidance or recommended architecture would be greatly appreciated.

Thank you!
