How to get ids of records created in a visual flow?

Hii Ravi,

While creating a record from a flow, there is an option "Assign the record id to a variable in a reference flow" right at the bottom of the page. You can assign the name to that particular variable and when creating the other child record you can use that variable to the field of the child opportunity and select the variable in the value.

In this way you can easily get the id of the parent record. And make sure the flow of the process is such that the parent is marked as an initial step of the process.

Thanks.
