In a standard lead conversion process (no apex, Require Validation for Converted Leads activated):
What influences the suggestions Attach to existing: {accountName}
during lead conversion? And: How can we influence the accounts that are shown?
I assumed adjusting matching and duplicate rules would also affect the suggestions made here, but apparently it does not work that way. Imagine 30 different "ABC Company" accounts. Currently they are all shown as suggestions but they have a distinct field "CustomerNumber" that is part of the matching and duplicate rule. The goal would be to only display suggestions that are actually found as a potential duplicate, eg. have a similar/the same name and a similar "CustomerNumber".
