Opportunity → Quotes Scenario: When a Quote is approved, automatically mark it as the Primary Quote and uncheck all other Quotes. Questions: • How do you update multiple child records? • How do you avoid recursive updates?

Hi @Rohit .

I would use a Record-Triggered Flow with a Scheduled Path on the Contract.

•  Set the Time Source = Contract End Date and Offset = 30 Days Before. 
•  At the scheduled time, check whether a Renewal Opportunity already exists. 
•  If not, use Create Records to create the Renewal Opportunity and notify the Account Owner. 
•  To prevent duplicates, use a Renewal Opportunity lookup or Renewal Created checkbox on the Contract. 

Flow: 

 Contract → Scheduled Path (30 Days Before End Date) → Duplicate Check → Create Renewal Opportunity → Notify Owner 

This is cleaner than calculating the 30-day window manually. Salesforce supports Scheduled Paths based on a date field with a positive or negative offset. 

Hope This Helps!!
