We use a Salesforce application created by a third party, which we have now taken over the management of.
We have a Process Builder process that creates a set of records in a different object when an Opportunity is marked as "Closed-Won". We've also had some of these records created in this object on a few rare occasions before the "Closed-Won" stage was reached (we know this as we record the Stage history).
We've searched through all the Process Builder entries - nothing relevant appears to be triggered from our Opportunity that could have done this.
Is there any way to search through Salesforce Setup, e.g. "Find all [things] that reference/create object type X" ?
